    I'm having problems decoding a string encoded in a byte array that I am reading from a BT-LE device.
    The input string is something like this ":12345678abcd"
    The raw data I get from reading the characteristic looks like this: [B@14db8bf7

    I have tried using the ByteConverter library, but it doesn't give the expected output, e.g.

    Sub ble_CharacteristicChanged (Characteristic As BleCharacteristic)
    Log("Get string value: " & Characteristic.GetStringValue(0))
    Dim bc As ByteConverter
    Log("String from byte: " & bc.StringFromBytes(Characteristic.GetValue, "ASCII"))
    This gives the output
    Get string value: ���
    String from byte: ���

    I found a Java example, that seems exactly what I need, based on creating a new string e.g.
    String s = new String(bytes);
    - but I'm not sure how to do this in B4A?

    SOLVED: I was reading from the wrong characteristic.
