https://devzone.nordicsemi.com/f/nordic-q-a/60403/experiment-with-nfcHi, I&#39;m experimenting with NFC using HRM example. Enabled my Android Phone NFC, programmed the example ( bonds clear ) . First pair works - touch , get the &quot;pair &quot; , click Yes , I can see the device on the Bonded list.

The example enters System OFF mode (deep sleep) after disconnect (see&nbsp;BLE_GAP_EVT_DISCONNECTED event) and the system is reset when it wakes up from System OFF.</p> <p>2. You may modify the example to&nbsp;always start advertising after wakeup.</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
