LoRaWAN
=======

Description
-----------

This application shows a simple use case of LoRaWAN with RIOT.

By using the real time clock and low-power capabilities of a board, this
application shows how to program a LoRaWAN Class A device using RIOT.

This application is using the Over-The-Air Activation procedure.

Usage
-----

Simply build and flash the application for a ST B-L072Z-LRWAN1 board:

    make flash term

Use the `BOARD`, `DRIVER` and `LORA_REGION` make variables to adapt the application
to your hardware setup and region of use:

- `BOARD` can be one of the nucleo-64 boards
- `DRIVER` can be either `sx1276` or `sx1272`
- `LORA_REGION` can be `EU868`, `US915`, etc (see LoRaWAN regional parameters for
  details).

ST Nucleo-64 can be used with mbed LoRa shields: there's one based on
[the sx1276 radio](https://os.mbed.com/components/SX1276MB1xAS/) and one based
on the [the sx1272 radio](https://os.mbed.com/components/SX1272MB2xAS/).

Finally, to join a LoRaWAN network using OTAA activation, use `make menuconfig`
inside the application and edit the configuration or edit the application
`Makefile` :

    DEVEUI ?= 0000000000000000
    APPEUI ?= 0000000000000000
    APPKEY ?= 00000000000000000000000000000000

## Automatic test

The automatic test replicates 11-lorawan release specs test:

- [11-lorawan](https://github.com/RIOT-OS/Release-Specs/blob/ba236c4a1d1258ab63d21b0a860d0f5a5935bbd4/11-lorawan/11-lorawan.md)
  - [Task #01 - LoRaWAN example](https://github.com/RIOT-OS/Release-Specs/blob/ba236c4a1d1258ab63d21b0a860d0f5a5935bbd4/11-lorawan/11-lorawan.md#task-01---lorawan-example)

It is recommended to test using iotlab-nodes. The default configuration is already
set on the application Makefile.

### Requirements

- The tests assumes that there is a gateway in all DR distance to the device and the
device was flashed with the correct keys.

- To use iotlab it is required to have a valid account for the FIT IoT-LAB
(registration there is open for everyone) and the [iot-lab/cli-tools](https://github.com/iot-lab/cli-tools) need to be installed.

- iotlab uses TTN lorawan gateways, to run the test you will need to create an
[account](https://account.thethingsnetwork.org/) add an [application](https://www.thethingsnetwork.org/docs/applications/add.html) and [register](https://www.thethingsnetwork.org/docs/devices/registration.html) a device. For this
test you need to take note of the Device EUI, Application EUI & Application Key
for that device.

### Usage

1. flash device with appropriate keys and test

    $ DEVEUI=<device eui> APPEUI=<application eui> APPKEY=<application key> make -C examples/lorawan/ flash test

#### With iotlab

1. setup the iotlab experiment:

    $ make -C examples/lorawan/ iotlab-exp

2. flash device, set appropriate keys and test

    $ DEVEUI=<device eui> APPEUI=<application eui> APPKEY=<application key> IOTLAB_NODE=auto make -C examples/lorawan/ flash test

3. stop the iotlab experiment:

    $ make -C examples/lorawan/ iotlab-stop

_note_: if you have multiple running experiments you will need to set `IOTLAB_EXP_ID`
        to the appropriate experiment, when using the `iotlab-exp` you will see a:
        `Waiting that experiment 175694 gets in state Running`. That number matches
        the experiment id you started.
