Connect ot bluetooth device

[Mihaill]

Hi!
I have

QBluetoothSocket *m_bluetoothSocket = new QBluetoothSocket(QBluetoothServiceInfo::RfcommProtocol);

I wont connected to bluetooth device. I do this:

m_bluetoothSocket->connectToService(device.m_address, device.m_uuid);

But I get error: QBluetoothSocket::SocketError::ServiceNotFoundError
How I can connected ot bluetooth device? How connected to device with password?

I check uuid, I get nulls. Why?

Hi,

Which version of Qt are you using ?
On which platform ?
To what kind of device are you trying to connect ?
Does it support that service ?
Etc.

I use Qt 5.15.2, Android 10. All bluetooth devices from QBluetoothDeviceInfo had null uuid. I dont know where target device. Same devices had name equal "".
