android - Can I connect bluetooth device automatically with the device which already paired without showing choose dialog -


i developing solution connection between obd2(vehicle ecu scanner) mobile app. want when ever obd device found , paired application automatically connect device , create socket transmission of data . without showing dialog box choose paired device.

you can connect paired bluetooth device, so, have know device's address , uuid. embedded devices may have defined uuid (for example, hc05 adapter), can uuid documentation. tricky part here have monitor failure , loss of connection can retry again. i'm implementing feature in home project, fell free see code: https://github.com/alexshutov/ledlights
