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 and one based on the the sx1272 radio.

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
  • 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 need to be installed.

• iotlab uses TTN lorawan gateways, to run the test you will need to create an account add an application and register 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= APPEUI= APPKEY= 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= APPEUI= APPKEY= IOTLAB_NODE=auto-ssh 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.
