Hi Balaji This is another question about bonding manager. In C:\Keil\ARM\Device\Nordic\nrf51822\Board\pca10001\s110\experimental\ble_app_uart project, it's a 128-bit UUID proprietary service. Apps will read this specific UUID to judge to connect. However, if there are over two uart module with same 128-bit UUID, it will be an issue for Mr. right iPHONE to connect to Mr. right UART device. In this case, could we add bonding manager in the souce code, then iPHONE will process pairing at 1st time connection. Can it work? Thanks

You may remove it from HRM but not from Proximity application because the Proximity profile specification mandates Security Level 2 or 3 (Encryption required). Bond Manager handles the security procedures for the application. Also note that by removing Bond Manager your application will need to handle the storage of known masters (if needed) and the System Attributes which is all done by the bond manager. Also you will need to handle the event BLE_GATTS_EVT_SYS_ATTR_MISSING whenever this event is generated by the SoftDevice.

Hi Balaji So, bonding manager is necessary for HRM and Proximity? Can we remove it? Thanks.

Hi Jeffery,

The HID examples (Keyboard and Mouse) demonstrate the use of the Directed Advertisement feature . They serve as example implementations to which you can refer to if you intend to use this feature in your own app.

The Heart Rate and Proximity applications very much use the Bond Manager for other purposes (like storing bonding information, whitelist advertisement (in case of proxmity), storing CCCDs etc).

Cheers, Balaji
