Bluetooth: Direct Advertising


Application demonstrating the BLE 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 BLE 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 BLE devices for Apple products refer to “Accessory Design Guidelines for Apple Devices”.


  • A board with BLE support

  • Second BLE device acting as a central with enabled privacy. For example another Zephyr board or any modern smartphone
