Linux Raspbian Jessie Lite, Bluez 5.40. I have a GATT server and my own agent for incoming "standard" bluetooth connections (i.e. A2DP).
I can successfully "connect" to the GATT server, but if the user doesn't accept the pairing confirmation (from the BT) I receive this error:
qt.bluetooth.bluez: Failed to create pairing "org.freedesktop.DBus.Error.NoReply"
as expected, but after a couple of seconds also the BLE connection will drop. I wonder if it's the correct behavior. I thought the BLE and BT connections are indipendent each other.
