title: Bluetooth RSSI values are always in dBm in all Android devices?
body: <p>I'm new to Android and my app uses Bluetooth to receive data from a small load cell amplifier. While in some devices (Samsung ones) the BT signal strength (RSSI) vary as expected (from around -20, at short distance, to around -80, at 10m), in some others (one LG model, at least) the RSSI are quite weird, as around 200 (positive value!) at short distance. I'm supposing that LG phone is not giving RSSI values in dBm. In all cases Samsung tablets and LG phones were always connected to the same remote device (the amplifier sample that my customer is developing). Actually my question is if it is normal, in this case, that different Android devices (or different Android versions) answer differently to the same API call.</p>
