How to detect Bluetooth Connection Type?

[ahsan737]

Greetings,

I am writing a Qt app that has to deal with Bluetooth SPP and BLE connection. I can communicate with a particular connection type in the individual app.
But, I want to write a single app that should detect the connection type and connect accordingly and communicate.

Can you please guide how to achieve this?

Best Regards,
Ahsan

@ahsan737 https://doc.qt.io/qt-5/qbluetoothdevicediscoveryagent.html allows you to set the Discovery Method https://doc.qt.io/qt-5/qbluetoothdevicediscoveryagent.html#DiscoveryMethod-enum
it's the easiest way to detect classic devices vs LE Devices
or if you discover all devices you can detect from QBluetoothDeviceInfo enum QBluetoothDeviceInfo::CoreConfiguration - check the flags to see if the device is a standard (classic) one, a BLE device or supports both
