[Interest] QtBluetooth Low Energy: How to find my peripheral?

[Prashant Vaibhav]

Hi all,

I’m using QtBluetooth low energy API on Qt 5.7 / Android 5/6. Targeting API level 19 (android 4.4+).

My problem is that I cannot find a way to decide which of the BLE devices returned during scan is mine:

- The advertising data is inaccessible (no API).
- The QBluetoothDeviceInfo.serviceUuids() function returns nothing (apparently it’s for classic bluetooth)
- The QBluetoothDeviceInfo.name() function is null (empty string)

So the only information I have is the rssi (QBluetoothDeviceInfo.rssi()), which is not enough to figure out the scanned device is ours. Furthermore, I cannot show a list to the user to pick the device manually, since all it will have is the signal level (and perhaps MAC address).

Any ideas?

Kind Regards,
Prashant Vaibhav
