Thanks for the response.
Is this just a difference of Android vs. Windows that our external BT device
doesn't show up as a serial device under Android like it does under Windows?
I don't think it will be a huge deal to rewrite, but 4 years ago when I started
writing the affected class we were "only ever going to run this application on
Windows using a USB to Serial adapter". So back then I created a class that
inherits from QSerialPort and started coding. I think based on what you're saying
about needing QBluetoothSocket under Android, and to make it more flexible in
general, I should probably just change that class to inherit from QObject and take a
QIODevice* so that I can swap out QSerialPort, QBluetoothSocket, or even
QTcpSocket if needed?
