Android Question problem with BLE, beacons, and reading the advertisement package

    I am trying to connect to an iBeacon via the app and I am using the trial version of b4a.
    my problems are as follows:
    1. The BeaconParser function is unavailable and the readRemoteRssi function is causing an error message = Cannot assign void value.
    2. My BleManager2_object.Scan2(Null,True) is not working as it causes the error

    3. Also, I am unable to find a function that reads the UID of the beacon and stores it in a string variable. GetCharacteristicData and ReadData and ReadData2 are not working.

    Can anyone please help with these three doubts?
