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.

Bluetooth: Observer
###################

Overview
********

A simple application demonstrating Bluetooth Low Energy Observer role
functionality. The application will periodically scan for devices nearby.
If any found, prints the address of the device, the RSSI value, the Advertising
type, and the Advertising data length to the console.

If the used Bluetooth Low Energy Controller supports Extended Scanning, you may
enable `CONFIG_BT_EXT_ADV` in the project configuration file. Refer to the
project configuration file for further details.

Requirements
************

* A board with Bluetooth Low Energy support

Building and Running
