It&#39;s round? If you have the MAC you can just do an if with that and p_adv_report-&gt;peer_addr and if it is true you can call sd_ble_gap_connect() with that address.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/68257?ContentTypeID=1Tue, 15 Nov 2016 23:27:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:928f6db6-1bb1-4c2f-bf94-7b90f9c0da02Jimmy<p>So the BLE device is a NRF52 dongle board which is the central. However the peripheral is a circular device that is intended to be used for automobile devices. I have the MAC address of the peripheral so would I use that to connect to the central dongle board. I am not sure. Will I need to use peer addressing? All I want is the peripheral device that is a circular device to pair with the central board.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/68256?ContentTypeID=1Tue, 15 Nov 2016 13:04:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:062df295-6240-43d9-a378-ba7566cd52c1Petter Myhre<p>What kind of BLE device do you want to connect to? ble_app_uart_c will look for advertisments that contain the NUS UUID, and try to connect.</p><div style="clear:both;"></div>
