Hi,

I cannot get this example code working running under linux with Qt 5.3.
http://qt-project.org/doc/qt-5/qtbluetooth-btchat-example.html

Captured debug output when running on the Desktop:
starting 
/home/andi/ims/sensor-fusion/bt/build-btchat-Desktop-Debug/btchat...
qt.bluetooth.bluez: Device does not support Bluetooth or 
"00:00:00:00:00:00" is not a valid local adapter
Cannot bind chat server to "00:00:00:00:00:00"


If I cross-compile it for android, start it on the android device and 
run "rfcomm connect hci0 XX:XX:XX:XX:XX:XX 5" on a terminal on the linux 
desktop, I can communicate with the app running on android by 
reading/writing to the file descriptor /dev/rfcomm0.

Can someone given me some hint what could be the problem?

With best regards,
Andreas
