2   :name: LoRa receive
3   :relevant-api: lora_api
4
5   Receive packets in both synchronous and asynchronous mode using the LoRa
6   radio.
7
8Overview
9********
10
11This sample demonstrates how to use the LoRa radio driver to receive packets
12both synchronously and asynchronously.
13
14In order to successfully receive messages, build and flash the accompanying
15LoRa send sample :zephyr:code-sample:`lora-send` on another board within range.
16
17As this sample receives a finite number of packets and then sleeps infinitely,
18the user must be ready to inspect the console output immediately after
19resetting the device.
20
21Building and Running
22********************
23
24Build and flash the sample as follows, changing ``b_l072z_lrwan1`` for
25your board, where your board has a ``lora0`` alias in the devicetree.
