Android device (Android12 Go Edition) cannot reconnect to BLE peripheral device

Step to reproduce

1. Several tries to connect / disconnect from Android device to peripheral BLE device.
2. If the disconnection occurs during the establishing of a connection with the discovered service, reconnection will be unavailable thereafter.

• • I have attached the log file when problem occurs. ( ble.log )

Cause of problem

• I think QLowEnergyController is in an abnormal state and cannot be reconnected, because reconnection becomes possible after calling QLowEnergyController::createCentral() and initializing QLowEnergyController.

Request

• If the QLowEnergyController is in an abnormal state and cannot be reconnected, then I would like QLowEnergyController::error() to be called to return some error status.

• • When a reconnection problem occurs, a call to QLowEnergyController::error() returns a status of QLowEnergyController::NoError.
  • I want to call QLowEnergyController::error() to check QLowEnergyController's error status and initialize it with QLowEnergyController::createCentral() if necessary. (as follow)

if (m_pController != nullptr) {
    if (m_pController->error() != QLowEnergyController::Error::NoError) {
       m_pController->disconnectFromDevice();
       delete m_pController;
        m_pController = nullptr;
          m_pController = QLowEnergyController::createCentral(m_currentDevice.getDevice());
    }
} 

Appendix

• When a reconnection problem occurs, a call to QLowEnergyController::error() returns a status of QLowEnergyController::ConnectionError on Android 11 Go Edition ( Lenovo Tab M7 3rd Gen ). However, on Android12 Go Edition, QLowEnergyController::Error::NoError is returned.
