There's no QBluetoothServiceInfo in there. The only reference in the source
serial_port->socket = new
I don't remember the Bluetooth code implementation anymore (even though I
mentored the student who wrote it). Is the code in qtserialbluetooth.cpp
running in an auxiliary thread, started by libdc?
I've attached a blind attempt at fixing this. I have no idea if it helps in any
way. It may make things even worse.
Can you run with QT_FATAL_WARNINGS=1 and then give me the backtrace of that
QObject::connect warning? (this requires that Qt print no other warnings
before this one) My guess is that this is the emission of the
