|
|
|
|
Receive packets in both synchronous and asynchronous mode using the LoRa
|
|
radio.
|
|
|
|
Overview
|
|
********
|
|
|
|
This sample demonstrates how to use the LoRa radio driver to receive packets
|
|
both synchronously and asynchronously.
|
|
|
|
In order to successfully receive messages, build and flash the accompanying
|
|
LoRa send sample :zephyr:code-sample:`lora-send` on another board within range.
|
|
|
|
As this sample receives a finite number of packets and then sleeps infinitely,
|
|
the user must be ready to inspect the console output immediately after
|
|
resetting the device.
|
|
|
|
Building and Running
|
|
********************
|
|
|
|
Build and flash the sample as follows, changing ``b_l072z_lrwan1`` for
|
|
your board, where your board has a ``lora0`` alias in the devicetree.
