I wanted to create Bluetooth connection between my laptop and the mobile phone.
the laptop has QT application and mobile has React-Native application. (laptop needs to act like a smart TV)
I need to host a Bluetooth server on the laptop and pair it using my mobile. How can I handle this? anybody who can help me, please?

Thank you so much for the reference. I tried it and failed to host the discoverable BT server. any simple guidelines, please?

No. That's as basic as the documentation offers (for a bluetooth server).

I'm going a hunch here, because you don't give us much information.You're on windows and using mingw ?
That doesn't work, that Bluetooth backend is a dummy oneqt.bluetooth: Dummy backend running. Qt Bluetooth module is non-functional.
you will have to use MSVC

ok, I don't have much experience with raspberry pi, so someone else will have to jump in.
But you're still not giving us much to go on here.
Some more questions, that will be of important either way.
- How did you install Qt on your pi? Compiled it yourself, cross compile, download precompiled...
- What Qt version exactly
- What pi model exactly
- Is your bluetooth on the pi correctly set up?
-
- Can you communicate with any Bluetooth device outside of Qt already ?
