LoRa receive

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 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.

west build -b b_l072z_lrwan1 zephyr/samples/drivers/lora/receive
west flash
