Ok thanks. I will check that.

[arthur ] sudo ./bluetoothd -nE -d src/gatt-database.
[sudo] password for arthur:

I replace the main.conf from source in /etc and retry the test :

[arthur ] sudo ./bluetoothd -nE -d src/gatt-database.
bluetoothd[11131]: Bluetooth daemon 5.39
bluetoothd[11131]: Starting SDP server

bluetoothd[11131]: hci0 Load Connection Parameters failed: Unknown Command (0x01)

This test is running on ubuntu 14.04. We stop bluetooth service before starting bluetoothd.
We also run the test on arm target but without trouble this time.

Arthur.
