At the HCI level, there is a command to read a Bluetooth link RSSI from the Bluetooth chipset (Read_RSSI_Command). However its implementation can vary from Bluetooth chipset to Bluetooth chipset. And the value returned is not always useful, for example if there are no packets transmitted in the last few minutes, the Bluetooth chipset has no way to know the current RSSI.
So we don't expose this in any Android Java API at this time.
