Scan & Advertise
Overview
A simple application demonstrating combined Bluetooth LE Broadcaster & Observer role functionality. The application will periodically send out advertising packets with a manufacturer data element. The content of the data is a single byte indicating how many advertising packets the device has received (the number will roll back to 0 after 255).
Requirements
BlueZ running on the host, or
A board with Bluetooth LE support
Building and Running
Build and flash the sample as follows, replacing <board> with your target board:
west build -b <board> samples/bluetooth/scan_adv
west flash
The sample interleaves advertising and scanning for nearby Bluetooth LE devices. The manufacturer data byte in the outgoing advertising packets reflects the number of advertising packets received. Use a Bluetooth scanner app (e.g. nRF Connect) to observe the advertising packets and watch the manufacturer data byte increment as the device receives packets from nearby devices.
