I'm wodering what the RSSI Value, delivered from the Android BluetoothDevice object, exactly means. Is it a value in dBm unit or only a measured signal stregth?

Thank you in advance.

The RSSI Value refers to the signal strength, and the dBm is the unit. dBm (sometimes dBmW) is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW).
