[Interest] QBluetooth connection/pairing issue

[Scott Bloom]

I am working on a tool that connects to a BT serial port device on windows 11

I have the scan working, and can select the device, giving me a QBluetoothServiceInfo

I can get the address via QBluetoothServiceInfo::device().address();

I can save this value to the registry, and reconnect on the startup of the tool.

However, I can't figure out for the life of me how to "pair" the device.

I turned on  all the Bluetooth logging, hoping to see something, via
QLoggingCategory::setFilterRules( QStringLiteral( "qt.bluetooth* = true" ) );

But that didn't help.

I construct the socket via
socket = new QBluetoothSocket( QBluetoothServiceInfo::RfcommProtocol);

I connect to all the socket signals, and never see a request or failure due to not being paired.

I then use

Socket->connectToService( address, QBluetoothUuid::ServiceClassUuid::SerialPort )

It works fine, if I have paired it outside of the app.  How do I pair it inside the app?
TIA,

Scott
