Direct Advertising
Overview
Application demonstrating the Bluetooth LE Direct Advertising capability. If no device is bonded to the peripheral, casual advertising will be performed. Once bonded, on every subsequent boot direct advertising to the bonded central will be performed. Additionally this sample provides two Bluetooth LE characteristics. To perform write, devices need to be bonded, while read can be done just after connection (no bonding required).
Please note that direct advertising towards iOS based devices is not allowed. For more information about designing Bluetooth LE devices for Apple products refer to “Accessory Design Guidelines for Apple Devices”.
Requirements
A board with Bluetooth LE support
Second Bluetooth LE device acting as a central with enabled privacy. For example another Zephyr board or any modern smartphone
Building and Running
Build and flash the sample as follows, replacing <board> with your target board:
west build -b <board> samples/bluetooth/direct_adv
west flash
After flashing, the device will start advertising. If no bond exists, it performs undirected advertising. After pairing completes, the device reboots after 5 seconds. On subsequent boots it uses directed advertising towards the bonded peer.
