# mobile senseBox
This is some Arduino code for GPS tracked senseBoxes.
They have an SDS011 particulate matter sensor & HDC1008 Temp & Humidity sensor
attached and transmit their measurements to opensensemap.org.
There are multiple variants to make use of various hardware I had available, and
to evaluate different use cases and workflows of data transmission.
Each sketch folder has its own readme with (more or less) detailed documentation.
The `libraries` folder contains all code that any sketch may depend on.
The the most simple solution to use these sketches is to make a backup of your
existing `~/Arduino` folder, and clone this repository there instead:
```sh
mv ~/Arduino ~/Arduino.bak
git clone https://github.com/noerw/mobile-sensebox ~/Arduino
```
## Hardware
The microcontroller & communication protocol differs for the sketches, but all
variants require a GPS device, a microcontroller with I2C, 2 UARTs (or some sort
of software UART), as well as an Novafit SDS011 & a Bosch HDC1008.
My builds of all these setups are powered by a 5.6Ah LiPo through an Adafruit
LiPo charger via USB, and enclosed in a 15x8x8 case.
The humidity sensor is included for reference, as the SDS011 only provides valid
data at low humidity. The sensor is enclosed within the case (which heats up
quite a bit), which makes the measurements quite inaccurate, they should only be
treated as approximations.
This setup is quite suboptimal for regular deployment (eg. daily commute by
bike), see `Future Work`.
### `./lora-gps`
Arduino Mega + Dragino LoRa & GPS Shield + senseBox Shield (SD card)
- transmitting data via LoRa to opensensemap.org through thethingsnetwork.org (details in SETUP.md)
- additionally saving to SD card if no LoRa coverage is available
- Arduino Uno should work as well, you need to play around with SoftSerial i guess..
### `./esp8266-gps`
Wemos D1 (ESP8266) + senseBox Shield
- stores measurements locally on 3MB SPIFFS, and uploads via WiFi when available
- requires installation of ESP8266 Arduino SDK, see `esp8266-gps/README.md`
- senseBox shield only used for ease of use with JST-connectors, not needed
### `./sdcard-gps`
Arduino Mega + senseBox Shield
- logging to SD card, manual upload to opensensemap.org
## Future Work
- Evaluation of SDS011 in a mobile environment: Influence of wind, sunlight,
vibrations, differing orientations
- Averaging of measurement values
- tradeoff: less outliers <-> smaller spatial acurracy
- Improved case
- power switch on the outside
- simple, quick mounting on a bike
- status LEDs about connectivity, GPS
- more neutral placement of humidity sensor
- all-weather proof

Arduino-LMIC library
====================
This repository contains the IBM LMIC (LoraMAC-in-C) library, slightly
modified to run in the Arduino environment, allowing using the SX1272,
SX1276 tranceivers and compatible modules (such as some HopeRF RFM9x
modules).
This library mostly exposes the functions defined by LMIC, it makes no
attempt to wrap them in a higher level API that is more in the Arduino
style. To find out how to use the library itself, see the examples, or
see the PDF file in the doc subdirectory.
This library requires Arduino IDE version 1.6.6 or above, since it
requires C99 mode to be enabled by default.
Installing
----------
To install this library:
- install it using the Arduino Library manager ("Sketch" -> "Include
Library" -> "Manage Libraries..."), or
- download a zipfile from github using the "Download ZIP" button and
install it using the IDE ("Sketch" -> "Include Library" -> "Add .ZIP
Library..."
- clone this git repository into your sketchbook/libraries folder.
For more info, see https://www.arduino.cc/en/Guide/Libraries
Features
--------
The LMIC library provides a fairly complete LoRaWAN Class A and Class B
implementation, supporting the EU-868 and US-915 bands. Only a limited
number of features was tested using this port on Arduino hardware, so be
careful when using any of the untested features.
What certainly works:
- Sending packets uplink, taking into account duty cycling.
- Encryption and message integrity checking.
- Receiving downlink packets in the RX2 window.
- Custom frequencies and datarate settings.
- Over-the-air activation (OTAA / joining).
What has not been tested:
- Receiving downlink packets in the RX1 window.
- Receiving and processing MAC commands.
- Class B operation.
If you try one of these untested features and it works, be sure to let
us know (creating a github issue is probably the best way for that).
Configuration
-------------
A number of features can be configured or disabled by editing the
`config.h` file in the library folder. Unfortunately the Arduino
environment does not offer any way to do this (compile-time)
configuration from the sketch, so be careful to recheck your
configuration when you switch between sketches or update the library.
At the very least, you should set the right type of transceiver (SX1272
vs SX1276) in config.h, most other values should be fine at their
defaults.
Supported hardware
------------------
This library is intended to be used with plain LoRa transceivers,
connecting to them using SPI. In particular, the SX1272 and SX1276
families are supported (which should include SX1273, SX1277, SX1278 and
SX1279 which only differ in the available frequencies, bandwidths and
spreading factors). It has been tested with both SX1272 and SX1276
chips, using the Semtech SX1272 evaluation board and the HopeRF RFM92
and RFM95 boards (which supposedly contain an SX1272 and SX1276 chip
respectively).
This library contains a full LoRaWAN stack and is intended to drive
these Transceivers directly. It is *not* intended to be used with
full-stack devices like the Microchip RN2483 and the Embit LR1272E.
These contain a transceiver and microcontroller that implements the
LoRaWAN stack and exposes a high-level serial interface instead of the
low-level SPI transceiver interface.
This library is intended to be used inside the Arduino environment. It
should be architecture-independent, so it should run on "normal" AVR
arduinos, but also on the ARM-based ones, and some success has been seen
running on the ESP8266 board as well. It was tested on the Arduino Uno,
Pinoccio Scout, Teensy LC and 3.x, ESP8266, Arduino 101.
This library an be quite heavy, especially if the fairly small ATmega
328p (such as in the Arduino Uno) is used. In the default configuration,
the available 32K flash space is nearly filled up (this includes some
debug output overhead, though). By disabling some features in `config.h`
(like beacon tracking and ping slots, which are not typically needed),
some space can be freed up. Some work is underway to replace the AES
encryption implementation, which should free up another 8K or so of
flash in the future, making this library feasible to run on a 328p
microcontroller.
Connections
-----------
To make this library work, your Arduino (or whatever Arduino-compatible
board you are using) should be connected to the transceiver. The exact
connections are a bit dependent on the transceiver board and Arduino
used, so this section tries to explain what each connection is for and
in what cases it is (not) required.
Note that the SX1272 module runs at 3.3V and likely does not like 5V on
its pins (though the datasheet is not say anything about this, and my
transceiver did not obviously break after accidentally using 5V I/O for
a few hours). To be safe, make sure to use a level shifter, or an
Arduino running at 3.3V. The Semtech evaluation board has 100 ohm resistors in
series with all data lines that might prevent damage, but I would not
count on that.
### Power
The SX127x transceivers need a supply voltage between 1.8V and 3.9V.
Using a 3.3V supply is typical. Some modules have a single power pin
(like the HopeRF modules, labeled 3.3V) but others expose multiple power
pins for different parts (like the Semtech evaluation board that has
`VDD_RF`, `VDD_ANA` and `VDD_FEM`), which can all be connected together.
Any *GND* pins need to be connected to the Arduino *GND* pin(s).
### SPI
The primary way of communicating with the transceiver is through SPI
(Serial Peripheral Interface). This uses four pins: MOSI, MISO, SCK and
SS. The former three need to be directly connected: so MOSI to MOSI,
MISO to MISO, SCK to SCK. Where these pins are located on your Arduino
varies, see for example the "Connections" section of the [Arduino SPI
documentation](SPI).
The SS (slave select) connection is a bit more flexible. On the SPI
slave side (the transceiver), this must be connect to the pin
(typically) labeled *NSS*. On the SPI master (Arduino) side, this pin
can connect to any I/O pin. Most Arduinos also have a pin labeled "SS",
but this is only relevant when the Arduino works as an SPI slave, which
is not the case here. Whatever pin you pick, you need to tell the
library what pin you used through the pin mapping (see below).
[SPI]: https://www.arduino.cc/en/Reference/SPI
### DIO pins
The DIO (digitial I/O) pins on the transceiver board can be configured
for various functions. The LMIC library uses them to get instant status
information from the transceiver. For example, when a LoRa transmission
starts, the DIO0 pin is configured as a TxDone output. When the
transmission is complete, the DIO0 pin is made high by the transceiver,
which can be detected by the LMIC library.
The LMIC library needs only access to DIO0, DIO1 and DIO2, the other
DIOx pins can be left disconnected. On the Arduino side, they can
connect to any I/O pin, since the current implementation does not use
interrupts or other special hardware features (though this might be
added in the feature, see also the "Timing" section).
In LoRa mode the DIO pins are used as follows:
* DIO0: TxDone and RxDone
* DIO1: RxTimeout
In FSK mode they are used as follows::
* DIO0: PayloadReady and PacketSent
* DIO2: TimeOut
Both modes need only 2 pins, but the tranceiver does not allow mapping
them in such a way that all needed interrupts map to the same 2 pins.
So, if both LoRa and FSK modes are used, all three pins must be
connected.
The pins used on the Arduino side should be configured in the pin
mapping in your sketch (see below).
### Reset
The transceiver has a reset pin that can be used to explicitely reset
it. The LMIC library uses this to ensure the chip is in a consistent
state at startup. In practice, this pin can be left disconnected, since
the transceiver will already be in a sane state on power-on, but
connecting it might prevent problems in some cases.
On the Arduino side, any I/O pin can be used. The pin number used must
be configured in the pin mapping (see below).
### RXTX
The transceiver contains two separate antenna connections: One for RX
and one for TX. A typical transceiver board contains an antenna switch
chip, that allows switching a single antenna between these RX and TX
connections. Such a antenna switcher can typically be told what
position it should be through an input pin, often labeled *RXTX*.
The easiest way to control the antenna switch is to use the *RXTX* pin
on the SX127x transceiver. This pin is automatically set high during TX
and low during RX. For example, the HopeRF boards seem to have this
connection in place, so they do not expose any *RXTX* pins and the pin
can be marked as unused in the pin mapping.
Some boards do expose the antenna switcher pin, and sometimes also the
SX127x *RXTX* pin. For example, the SX1272 evaluation board calls the
former *FEM_CTX* and the latter *RXTX*. Again, simply connecting these
together with a jumper wire is the easiest solution.
Alternatively, or if the SX127x *RXTX* pin is not available, LMIC can be
configured to control the antenna switch. Connect the antenna switch
control pin (e.g. *FEM_CTX* on the Semtech evaluation board) to any I/O
pin on the Arduino side, and configure the pin used in the pin map (see
below). It is not entirely clear why would *not* want the transceiver to
control the antenna directly, though.
### Pin mapping
As described above, most connections can use arbitrary I/O pins on the
Arduino side. To tell the LMIC library about these, a pin mapping struct
is used in the sketch file.
For example, this could look like this:
lmic_pinmap lmic_pins = {
.nss = 6,
.rxtx = LMIC_UNUSED_PIN,
.rst = 5,
.dio = {2, 3, 4},
};
The names refer to the pins on the transceiver side, the numbers refer
to the Arduino pin numbers (to use the analog pins, use constants like
`A0`). For the DIO pins, the three numbers refer to DIO0, DIO1 and DIO2
respectively. Any pins that are not needed should be specified as
`LMIC_UNUSED_PIN`. The nss and dio0 pin is required, the others can
potentially left out (depending on the environments and requirements,
see the notes above for when a pin can or cannot be left out).
The name of this struct must always be `lmic_pins`, which is a special name
recognized by the library.
#### LoRa Nexus by Ideetron
This board uses the following pin mapping:
const lmic_pinmap lmic_pins = {
.nss = 10,
.rxtx = LMIC_UNUSED_PIN,
.rst = LMIC_UNUSED_PIN, // hardwired to AtMega RESET
.dio = {4, 5, 7},
};
Examples
--------
This library currently provides three examples:
- `ttn-abp.ino` shows a basic transmission of a "Hello, world!" message
using the LoRaWAN protocol. It contains some frequency settings and
encryption keys intended for use with The Things Network, but these
also correspond to the default settings of most gateways, so it
should work with other networks and gateways as well. This example
uses activation-by-personalization (ABP, preconfiguring a device
address and encryption keys), and does not employ over-the-air
activation.
Reception of packets (in response to transmission, using the RX1 and
RX2 receive windows is also supported).
- `ttn-otaa.ino` also sends a "Hello, world!" message, but uses over
the air activation (OTAA) to first join a network to establish a
session and security keys. This was tested with The Things Network,
but should also work (perhaps with some changes) for other networks.
- `raw.ino` shows how to access the radio on a somewhat low level,
and allows to send raw (non-LoRaWAN) packets between nodes directly.
This is useful to verify basic connectivity, and when no gateway is
available, but this example also bypasses duty cycle checks, so be
careful when changing the settings.
Timing
------
Unfortunately, the SX127x tranceivers do not support accurate
timekeeping themselves (there is a sequencer that is *almost* sufficient
for timing the RX1 and RX2 downlink windows, but that is only available
in FSK mode, not in LoRa mode). This means that the microcontroller is
responsible for keeping track of time. In particular, it should note
when a packet finished transmitting, so it can open up the RX1 and RX2
receive windows at a fixed time after the end of transmission.
This timing uses the Arduino `micros()` timer, which has a granularity
of 4μs and is based on the primary microcontroller clock. For timing
events, the tranceiver uses its DIOx pins as interrupt outputs. In the
current implementation, these pins are not handled by an actual
interrupt handler, but they are just polled once every LMIC loop,
resulting in a bit inaccuracy in the timestamping. Also, running
scheduled jobs (such as opening up the receive windows) is done using a
polling approach, which might also result in further delays.
Fortunately, LoRa is a fairly slow protocol and the timing of the
receive windows is not super critical. To synchronize transmitter and
receiver, a preamble is first transmitted. Using LoRaWAN, this preamble
consists of 8 symbols, of which the receiver needs to see 4 symbols to
lock on. The current implementation tries to enable the receiver for 5
symbol times at 1.5 symbol after the start of the receive window,
meaning that a inacurracy of plus or minus 2.5 symbol times should be
acceptable.
At the fastest LoRa setting supported by the tranceiver (SF5BW500) a
single preamble symbol takes 64μs, so the receive window timing should
be accurate within 160μs (for LoRaWAN this is SF7BW250, needing accuracy
within 1280μs). This is certainly within a crystal's accuracy, but using
the internal oscillator is probably not feasible (which is 1% - 10%
accurate, depending on calibration). This accuracy should also be
feasible with the polling approach used, provided that the LMIC loop is
run often enough.
It would be good to properly review this code at some point, since it
seems that in some places some offsets and corrections are applied that
might not be appropriate for the Arduino environment. So if reception is
not working, the timing is something to have a closer look at.
The LMIC library was intended to connect the DIO pins to interrupt
lines and run code inside the interrupt handler. However, doing this
opens up an entire can of worms with regard to doing SPI transfers
inside interrupt routines (some of which is solved by the Arduino
`beginTransaction()` API, but possibly not everything). One simpler
alternative could be to use an interrupt handler to just store a
timestamp, and then do the actual handling in the main loop (this
requires modifications of the library to pass a timestamp to the LMIC
`radio_irq_handler()` function).
An even more accurate solution could be to use a dedicated timer with an
input capture unit, that can store the timestamp of a change on the DIO0
pin (the only one that is timing-critical) entirely in hardware.
Unfortunately, timer0, as used by Arduino's `millis()` and `micros()`
functions does not seem to have an input capture unit, meaning a
separate timer is needed for this.
If the main microcontroller does not have a crystal, but uses the
internal oscillator, the clock output of the transceiver (on DIO5) could
be usable to drive this timer instead of the main microcontroller clock,
to ensure the receive window timing is sufficiently accurate. Ideally,
this would use timer2, which supports asynchronous mode (e.g. running
while the microcontroller is sleeping), but that timer does not have an
input capture unit. Timer1 has one, but it seems it will stop running
once the microcontroller sleeps. Running the microcontroller in idle
mode with a slower clock might be feasible, though. Instead of using the
main crystal oscillator of the transceiver, it could be possible to use
the transceiver's internal RC oscillator (which is calibrated against
the transceiver crystal), or to calibrate the microcontroller internal
RC oscillator using the transceiver's clkout. However, that datasheet is
a bit vague on the RC oscillator's accuracy and how to use it exactly
(some registers seem to be FSK-mode only), so this needs some
experiments.
Downlink datarate
-----------------
Note that the datarate used for downlink packets in the RX2 window
defaults to SF12BW125 according to the specification, but some networks
use different values (iot.semtech.com and The Things Network both use
SF9BW). When using personalized activate (ABP), it is your
responsibility to set the right settings, e.g. by adding this to your
sketch (after calling `LMIC_setSession`). `ttn-abp.ino` already does
this.
LMIC.dn2Dr = DR_SF9;
When using OTAA, the network communicates the RX2 settings in the
join accept message, but the LMIC library does not currently process
these settings. Until that is solved (see issue #20), you should
manually set the RX2 rate, *after* joining (see the handling of
`EV_JOINED` in the `ttn-otaa.ino` for an example.

# LoRaWAN serialization/deserialization library for The Things Network
[![Build Status](https://travis-ci.org/thesolarnomad/lora-serialization.svg?branch=master)](https://travis-ci.org/thesolarnomad/lora-serialization)
[![Coverage Status](https://coveralls.io/repos/github/thesolarnomad/lora-serialization/badge.svg?branch=master)](https://coveralls.io/github/thesolarnomad/lora-serialization?branch=master)
[![semantic-release](https://img.shields.io/badge/%20%20%F0%9F%93%A6%F0%9F%9A%80-semantic--release-e10079.svg)](https://github.com/semantic-release/semantic-release)
This fully unit-tested library allows you to encode your data on the Arduino side and decode it on the [TTN](https://console.thethingsnetwork.org/) side. It provides both a C-based encoder and a JavaScript-based decoder.
Since version 2.2.0 there is also an encoder for the TTN side.
## In short
### Encoding on Arduino, decoding in TTN
Arduino side:
```cpp
#include "LoraMessage.h"
LoraMessage message;
message
.addUnixtime(1467632413)
.addLatLng(-33.905052, 151.26641);
lora_send_bytes(message.getBytes(), message.getLength());
delete message;
```
TTN side:
```javascript
// include src/decoder.js
var json = decode(bytes, [unixtime, latLng], ['time', 'coords']);
// json == {time: unixtime, coords: [latitude, longitude]}
```
### Encoding in TTN
TTN side:
```javascript
// include src/encoder.js
var bytes = encode([timestamp, [latitude, longitude]], [unixtime, latLng]);
// bytes is of type Buffer
```
#### With the convenience class
```javascript
// include src/encoder.js
// include src/LoraMessage.js
var bytes = new LoraMessage(encoder)
.addUnixtime(1467632413)
.addLatLng(-33.905052, 151.26641)
.addBitmap(true, true, false, true)
.getBytes();
// bytes = <Buffer 1d 4b 7a 57 64 a6 fa fd 6a 24 04 09 d0>
```
and then decoding as usual:
```js
var result = decoder.decode(
bytes,
[decoder.unixtime, decoder.latLng, decoder.bitmap],
['time', 'coords', 'heaters']
);
// result =
// { time: 1467632413,
// coords: [ -33.905052, 151.26641 ],
// heaters:
// { a: true,
// b: true,
// c: false,
// d: true,
// e: false,
// f: false,
// g: false,
// h: false } }
```
## General Usage
### Unix time (4 bytes)
Serializes/deserializes a unix time (seconds)
```cpp
#include "LoraEncoder.h"
byte buffer[4];
LoraEncoder encoder(buffer);
encoder.writeUnixtime(1467632413);
// buffer == {0x1d, 0x4b, 0x7a, 0x57}
```
and then in the TTN frontend, use the following method:
```javascript
unixtime(bytes.slice(x, x + 4)) // 1467632413
```
### GPS coordinates (8 bytes)
Serializes/deserializes coordinates (latitude/longitude) with a precision of 6 decimals.
```cpp
#include "LoraEncoder.h"
byte buffer[8];
LoraEncoder encoder(buffer);
encoder.writeLatLng(-33.905052, 151.26641);
// buffer == {0x64, 0xa6, 0xfa, 0xfd, 0x6a, 0x24, 0x04, 0x09}
```
and then in the TTN frontend, use the following method:
```javascript
latLng(bytes.slice(x, x + 8)) // [-33.905052, 151.26641]
```
### Unsigned 8bit Integer (1 byte)
Serializes/deserializes an unsigned 8bit integer.
```cpp
#include "LoraEncoder.h"
byte buffer[1];
LoraEncoder encoder(buffer);
uint8_t i = 10;
encoder.writeUint8(i);
// buffer == {0x0A}
```
and then in the TTN frontend, use the following method:
```javascript
uint8(bytes.slice(x, x + 1)) // 10
```
### Unsigned 16bit Integer (2 bytes)
Serializes/deserializes an unsigned 16bit integer.
```cpp
#include "LoraEncoder.h"
byte buffer[2];
LoraEncoder encoder(buffer);
uint16_t i = 23453;
encoder.writeUint16(i);
// buffer == {0x9d, 0x5b}
```
and then in the TTN frontend, use the following method:
```javascript
uint16(bytes.slice(x, x + 2)) // 23453
```
### Temperature (2 bytes)
Serializes/deserializes a temperature reading between -327.68 and +327.67 (inclusive) with a precision of 2 decimals.
```cpp
#include "LoraEncoder.h"
byte buffer[2];
LoraEncoder encoder(buffer);
encoder.writeTemperature(-123.45);
// buffer == {0xcf, 0xc7}
```
and then in the TTN frontend, use the following method:
```javascript
temperature(bytes.slice(x, x + 2)) // -123.45
```
### Humidity (2 bytes)
Serializes/deserializes a humidity reading between 0 and 100 (inclusive) with a precision of 2 decimals.
```cpp
#include "LoraEncoder.h"
byte buffer[2];
LoraEncoder encoder(buffer);
encoder.writeHumidity(99.99);
// buffer == {0x0f, 0x27}
```
and then in the TTN frontend, use the following method:
```javascript
humidity(bytes.slice(x, x + 2)) // 99.99
```
### Bitmap (1 byte)
Serializes/deserializes a bitmap containing between 0 and 8 different flags.
```cpp
#include "LoraEncoder.h"
byte buffer[1];
LoraEncoder encoder(buffer);
encoder.writeBitmap(true, false, false, false, false, false, false, false);
// buffer == {0x80}
```
and then in the TTN frontend, use the following method:
```javascript
bitmap(bytes.slice(x, x + 1)) // { a: true, b: false, c: false, d: false, e: false, f: false, g: false, h: false }
```
## Composition
### On the Arduino side
The decoder allows you to write more than one value to a byte array:
```cpp
#include "LoraEncoder.h"
byte buffer[19];
LoraEncoder encoder(buffer);
encoder.writeUnixtime(1467632413);
encoder.writeLatLng(-33.905052, 151.26641);
encoder.writeUint8(10);
encoder.writeUint16(23453);
encoder.writeTemperature(80.12);
encoder.writeHumidity(99.99);
encoder.writeBitmap(true, false, false, false, false, false, false, false);
/* buffer == {
0x1d, 0x4b, 0x7a, 0x57, // Unixtime
0x64, 0xa6, 0xfa, 0xfd, 0x6a, 0x24, 0x04, 0x09, // latitude,longitude
0x0A, // Uint8
0x9d, 0x5b, // Uint16
0x1f, 0x4c, // temperature
0x0f, 0x27, // humidity
0x80 // bitmap
}
*/
```
#### Convenience class `LoraMessage`
There is a convenience class that represents a LoraMessage that you can add readings to:
```cpp
#include "LoraMessage.h"
LoraMessage message;
message
.addUnixtime(1467632413)
.addLatLng(-33.905052, 151.26641)
.addUint8(10)
.addUint16(23453)
.addTemperature(80.12)
.addHumidity(99.99)
.addBitmap(false, false, false, false, false, false, true, false);
send(message.getBytes(), message.getLength());
/*
getBytes() == {
0x1d, 0x4b, 0x7a, 0x57, // Unixtime
0x64, 0xa6, 0xfa, 0xfd, 0x6a, 0x24, 0x04, 0x09, // latitude,longitude
0x0A, // Uint8
0x9d, 0x5b, // Uint16
0x1f, 0x4c, // temperature
0x0f, 0x27, // humidity
0xfd // Bitmap
}
and
getLength() == 20
*/
```
### Composition in the TTN decoder frontend with the `decode` method
The `decode` method allows you to specify a mask for the incoming byte buffer (that was generated by this library) and apply decoding functions accordingly.
```javascript
decode(byte Array, mask Array [,mapping Array])
```
#### Example
Paste everything from `src/decoder.js` into the decoder method and use like this:
```javascript
function (bytes) {
// code from src/decoder.js here
return decode(bytes, [latLng, unixtime], ['coords', 'time']);
}
```
This maps the incoming byte buffer of 12 bytes to a sequence of one `latLng` (8 bytes) and one `unixtime` (4 bytes) sequence and maps the first one to a key `coords` and the second to a key `time`.
You can use: `64 A6 FA FD 6A 24 04 09 1D 4B 7A 57` for testing, and it will result in:
```json
{
"coords": [
-33.905052,
151.26641
],
"time": 1467632413
}
```
##### Example decoder in the TTN console
Set up your decoder in the console:
![TTN console decoder example](https://cloud.githubusercontent.com/assets/188038/23703580/c136cc90-0454-11e7-9570-ae137136d7b5.png)
##### Example converter in the TTN console
The decode method already does most of the necessary transformations, so in most cases you can just pass the data through:
![TTN console converter example](https://cloud.githubusercontent.com/assets/188038/23703587/c99021c0-0454-11e7-8670-9f77472a111d.png)
## Development
* Install the dependencies via `yarn`
* Run the unit tests (C) via `yarn run test:c`
* Run the unit tests (JavaScript) via `yarn test`
* Check the coverage (JavaScript) via `yarn coverage` (see `coverage/lcov-report`)
The CI will kick off once you create a pull request automatically.

# SDS011 library selectable serialport
Arduino library for dust Sensor SDS011 (Nova Fitness Co.,Ltd) which allows to choose the serial port used to communicate with the sensor.
Based on the work of [ricky-z](https://github.com/ricki-z/SDS011)
## Usage
* Define SDS object:
```
SDS011(Stream& serial);
```
i.e. SDS011 mySDS(Serial1);
* Start serial communication:
```
Serial1.begin(9600);
```
* Read values:
```
int read(float *p25, float *p10);
```
i.e. error = mySDS(pm25,pm10);
Reads the PM2.5 and PM10 values, return code is 0, if new values were read, and 1 if there were no new values.

The Arduino SdFat library provides read/write access to FAT16/FAT32
file systems on SD/SDHC flash cards.
SdFat requires Arduino 1.6x or greater.
Key changes:
The SPI divisor has been replaced by SPISettings in the begin() call.
```
bool begin(uint8_t csPin = SS, SPISettings spiSettings = SPI_FULL_SPEED);
```
Several macros have been defined for backward compatibility.
```
#define SD_SCK_MHZ(maxMhz) SPISettings(1000000UL*maxMhz, MSBFIRST, SPI_MODE0)
// SPI divisor constants
/** Set SCK to max possible rate. */
#define SPI_FULL_SPEED SD_SCK_MHZ(50)
/** Set SCK rate to F_CPU/3 for Due */
#define SPI_DIV3_SPEED SD_SCK_HZ(F_CPU/3)
/** Set SCK rate to F_CPU/4. */
#define SPI_HALF_SPEED SD_SCK_HZ(F_CPU/4)
// ...
```
There are two new classes, SdFatEX and SdFatSoftSpiEX.
Teensy 3.5/3.6 SDIO support has been added. Try the TeensySdioDemo example.
Many other example will work with Teensy SDIO if you use the SdFatSdio classes
and call begin with no parameters.
```
SdFatSdio sd;
....
if (!sd.begin()) {
// Handle failure.
}
```
Please read changes.txt and the html documentation in the extras folder for more information.
Please report problems as issues.
A number of configuration options can be set by editing SdFatConfig.h
define macros. See the html documentation for details
Please read the html documentation for this library. Start with
html/index.html and read the Main Page. Next go to the Classes tab and
read the documentation for the classes SdFat, SdFatEX, SdBaseFile,
SdFile, File, StdioStream, ifstream, ofstream, and others.
Please continue by reading the html documentation.

/**
* This program logs data from the Arduino ADC to a binary file.
*
* Samples are logged at regular intervals. Each Sample consists of the ADC
* values for the analog pins defined in the PIN_LIST array. The pins numbers
* may be in any order.
*
* Edit the configuration constants below to set the sample pins, sample rate,
* and other configuration values.
*
* If your SD card has a long write latency, it may be necessary to use
* slower sample rates. Using a Mega Arduino helps overcome latency
* problems since 13 512 byte buffers will be used.
*
* Each 512 byte data block in the file has a four byte header followed by up
* to 508 bytes of data. (508 values in 8-bit mode or 254 values in 10-bit mode)
* Each block contains an integral number of samples with unused space at the
* end of the block.
*
* Data is written to the file using a SD multiple block write command.

/**
* This program logs data to a binary file. Functions are included
* to convert the binary file to a csv text file.
*
* Samples are logged at regular intervals. The maximum logging rate
* depends on the quality of your SD card and the time required to
* read sensor data. This example has been tested at 500 Hz with
* good SD card on an Uno. 4000 HZ is possible on a Due.
*
* If your SD card has a long write latency, it may be necessary to use
* slower sample rates. Using a Mega Arduino helps overcome latency
* problems since 12 512 byte buffers will be used.
*
* Data is written to the file using a SD multiple block write command.

/**
* This program logs data to a binary file. Functions are included
* to convert the binary file to a csv text file.
*
* Samples are logged at regular intervals. The maximum logging rate
* depends on the quality of your SD card and the time required to
* read sensor data. This example has been tested at 500 Hz with
* good SD card on an Uno. 4000 HZ is possible on a Due.
*
* If your SD card has a long write latency, it may be necessary to use
* slower sample rates. Using a Mega Arduino helps overcome latency
* problems since 12 512 byte buffers will be used.
*
* Data is written to the file using a SD multiple block write command.

/**
* This program logs data to a binary file. Functions are included
* to convert the binary file to a csv text file.
*
* Samples are logged at regular intervals. The maximum logging rate
* depends on the quality of your SD card and the time required to
* read sensor data. This example has been tested at 500 Hz with
* good SD card on an Uno. 4000 HZ is possible on a Due.
*
* If your SD card has a long write latency, it may be necessary to use
* slower sample rates. Using a Mega Arduino helps overcome latency
* problems since 12 512 byte buffers will be used.
*
* Data is written to the file using a SD multiple block write command.
