https://devzone.nordicsemi.com/f/nordic-q-a/181/bonding-only-when-client-is-close-to-serverWhat&#39;s the proper way to implement bonding that depends on proximity (rather than a whitelist)? So when the client (phone) is close (say, five to ten centimeters) to the server (BTLE peripheral) then there is a bond created and the devices can now communicateen-USTelligent Community 13Thu, 01 Aug 2013 11:49:39 GMThttps://devzone.nordicsemi.com/thread/1002?ContentTypeID=1Thu, 01 Aug 2013 11:49:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a3da1ca4-c9af-4579-af47-16861f9858c8Ole Morten<p>To clean things up, I&#39;d be happy if you could evaluate the answer you have received and accept it if you feel it&#39;s sufficient.

RSSI monitoring can be enabled when in a connection with sd_ble_gap_rssi() start.</p><div style="clear:both;"></div>
