This is an issue related to the Android 12 update. The currently published BluetoothLE extension is not aware of Google's latest changes to Bluetooth, and so it fails for that reason. You should be able to use the AskForPermission block to request the BLUETOOTH_SCAN and BLUETOOTH_CONNECT permissions to connect to BLE devices on Android 12+.
Edit: I should mention that I am in the process of updating the BLE extension to address the changes in Android 12. Please keep an eye on the IOT category of this community for the update announcement.
