Hi Emanuele,
Sometimes, the Bluetooth module vendor provides absolute signal strength (like Wi-Fi) rather than the relative RSSI value indicated in Bluetooth Spec. I had one dongle which did just that. You may need to send your inquiry to them as well if it's really the case.

Thanks

I'm referring to this function (from bluez dbus-api) where the rssi parameter is int16

----
void RemoteDeviceFound(string address, uint32 class, int16 rssi)

            This signal will be send every time an inquiry result 
            has been found by the service daemon. In general they
            only appear during a device discovery.

you posted in another thread you can use that value to check how close is the remote device to the dongle who does inquiry. Maybe I'm wrong and that's not the correct value to check for this purpose? 
Anyway the third parameter I read with the snipped code I posted is negative.
