Overview

The sample initializes the radio notification library and registers a handler that triggers both when the radio is enabled and when it is disabled. The handler then toggles LED 2 based on the current state of the radio.

User interface

LED 0:

Lit when the device is initialized.

LED 1:

Lit when a device is connected.

LED 2:

ON when a “radio on” notification is received, OFF when a “radio off” notification is received.

Building and running

This sample can be found under samples/bluetooth/ble_radio_notification/ in the Bare Metal folder structure.

For details on how to create, configure, and program a sample, see Getting Started with the samples.

Testing

You can test this sample using nRF Connect for Desktop with the Serial Terminal app. Make sure that these are installed before starting the testing procedure.

1. Compile and program the application.

2. In the Serial Terminal, observe that the BLE Radio Notification sample initialized message is printed.

3. Observe that the LED 2 blinks while the device is advertising and the radio is active.

4. Observe that the LED 2 stops blinking when advertising stops.
