However we recommend storing dynamic data as soon as you are done bonding as you never really know the state of your battery. Or if the end user will turn of power before you have time to store the dynamic data.</p> <p>If the nRF8001 is power cycled or reset and you didn&#39;t store the dynamic data, you will also have to delete the bond information on the peer and redo the bond process to be able to connect to the peer again.</p><div style="clear:both;"></div>
