Hi Pspavi,

Please let us know which devices you are planing to connect to ? Are they phones or they are other nRF52 chip ?

To get the nRF52 MAC address, you can call sd_ble_gap_addr_get() to get the address. Please have a look in the documentation for more information on how to use it.

Please study fundamental of Bluetooth Low Energy. And try our example, for example in the SDK, for example ble_app_hids_mouse, ble_app_proximity.

Hi,

When you get connected (BLE_GAP_EVT_CONNECTED event) you can find the address of the peer device in p_ble_evt->gap_evt.connected.peer_addr

But this is only valid for those use static random/public address. Those address that wouldn't change over time. Most phones today use random resolvable address which change every 15 minutes.

To be able to recognize those device, you would need to bond to them to get the IRK key to reconnect.

I would suggest you to get familiar with the bonding concept in Bluetooth Low Energy.
