Bluetooth: High Duty Cycle Directed Advertising

Overview

A simple Bluetooth LE application that demonstrates high duty cycle directed advertising to a randomly generated target address. The application generates a random target address at startup and then starts directed advertising using high duty cycle intervals as defined by the Bluetooth specification for directed advertising.

This sample is useful for testing WURX (Wake-up receive) functionality with EVK to EVK communication. See the openair/samples/bluetooth/sensor_beacon application.

Building and Running

This sample is built from openair/samples/bluetooth/high_duty_adv.

Build command:

west build -p always -b <BOARD> openair/samples/bluetooth/high_duty_adv --sysbuild -T samples.bluetooth.high_duty_adv.atm

Flash command:

west flash --no-rebuild --device <DEVICE_ID> --jlink --fast_load [--erase_flash]
