As part of the pairing procedure, there is an option of also doing &quot;bonding&quot;. If you do bonding, the devices will store information about the peer device in persistent memory, so that they can reestablish the encrypted connection at a later point in time, but without having to do the full pairing procedure all over again. It can then &quot;continue the existing connection&quot; the next time the same two devices connects to each other, as long as both devices have stored their part of the bonding data.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
