I'm testing a bluetooth application running on an Android device. I registered a dummy service on the device and opened the RFCOMM channels to it from the PC running Ubuntu 12.04:
bluez-test-serial 7C:E9:D3:DE:03:0A 43502780-ef1e-11e2-b778-0800200c9a66
/dev/rfcomm0 alright, but immediately after I'm catching channel input on the device side. It reads
AT+GC. Surprisingly, it seems to happen only the first time after I login.
I grepped through the BlueZ sources to no avail.
Does anybody know what could be the source of this unsolicited AT command being fed into the channel?
