I was hoping I could use the QBluetoothSocket connection.

However it sounds like a background service that does the Bluetooth communications must be pure java? No Qt, no C++.

My Qt widget app has Bluetooth connection that broadcasts GPS NMEA data to a
connected device.

How can I maintain this connection streaming GPS data when app is not in
foreground or device is in sleep?

Is it even possible to run Qt C++ code on Android in the background?

Does Qt have any example for this?

Is a Background Service what I need?

Creating a Background Service

Thanks in advance for any tips or direction,

Yes, Qt application for android is a normal android application, so
you really need service. I was trying to do something like that last
year, the most convenient way I've found was to open the builded
project in Android Studio, fix the gradle errors, then change all you
need to make it a service. But by that time you need your Qt part
already working. I was stuck on the front-end side though, so dropped
the idea to use Qt for normal applications.
