History

Keith Packard 0b90fd5adf samples, tests, boards: Switch main return type from void to int As both C and C++ standards require applications running under an OS to return 'int', adapt that for Zephyr to align with those standard. This also eliminates errors when building with clang when not using -ffreestanding, and reduces the need for compiler flags to silence warnings for both clang and gcc. Most of these changes were automated using coccinelle with the following script: @@ @@ - void + int main(...) { ... - return; + return 0; ... } Approximately 40 files had to be edited by hand as coccinelle was unable to fix them.

LoRaWAN Class A Sample
######################

Overview
********

A simple application to demonstrate the LoRaWAN subsystem of Zephyr.

Building and Running
********************

This sample can be found under
:zephyr_file:`samples/subsys/lorawan/class_a` in the Zephyr tree.

Before building the sample, make sure to select the correct region in the
``prj.conf`` file.

The following commands build and flash the sample.

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/lorawan/class_a
   :board: nucleo_wl55jc
   :goals: build flash

Extended Configuration
**********************

This sample can be configured to run the application-layer clock
synchronization service in the background.

The following commands build and flash the sample with clock synchronization
enabled.

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/lorawan/class_a
   :board: nucleo_wl55jc
   :goals: build flash
