I build android ble peripheral app and starting advertaising. When i did it, MAC address alwalse random generate. (name peripheral = BIBKA, MAC address = 62:1E:6E:6C:48:E9) 2.

Could also be that it connects to any device that advertises the correct services, but in this case I guess you click what device to connect to? As for bonding that is using EDIV and RAND to fetch the keys from the data base and once connected the address doesn&#39;t really have any function.</p><div style="clear:both;"></div>
