https://devzone.nordicsemi.com/f/nordic-q-a/15699/unpairing-from-central-from-nrf52I have an nRF52 paired to a central device. In order to delete the pairing on the nRF52 I clear the persistent data (dm_init_param_t). I notice, however, that even though the pairing data is gone, the central device is still connecting with the nRF52en-USTelligent Community 13Fri, 12 Aug 2016 06:29:19 GMThttps://devzone.nordicsemi.com/thread/59946?ContentTypeID=1Fri, 12 Aug 2016 06:29:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:23cdc05b-9ee8-465d-a948-937fd6d1fb51J&#248;rgen Kvalvaag<p>In this scenario the central must already know that the bond is missing. Most likely, it will create a new bond to replace the old one.</p> <p>When the central initiates the security procedure, it first asks the peripheral to encrypt the link using stored keys. If no known bond exists in the peripheral, it will reply that the keys are missing.</p> <p>The central is then free to start a new bonding procedure, which Device Manager by default will accept.</p> <p>The SoftDevice documentation contains some nice message sequence charts that describe these procedures in detail. <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s130.api.v2.0.0/group___b_l_e___g_a_p___m_s_c.html">Link s130 docs</a></p><div style="clear:both;"></div>
