https://devzone.nordicsemi.com/f/nordic-q-a/45709/selective-pop-up-pairing-functionHello! I am using SDK 15.3.0 to develop the NRF52832 firmware. At present, I want to implement a function, when the device is connected to the IOS host, start pairing, and when connected to the ANDROID host, no pairing window will pop up.

You can comment out this line &quot;pm_handler_secure_on_connection(p_ble_evt);&quot; in ble_evt_handler() to stop the peer manager from sending a pairing request on the connection event, and instead request pairing manually if the following conditions are met (use pm_conn_secure() to request pairing):</p> <p>- Peer is not previously&nbsp;bonded</p> <p>- ANCS service is discovered</p><div style="clear:both;"></div>
