Solution 1:

You can only get the RSSI value during a device discovery scan. (Bluetooth Discovery vs Connection)

"Is it easier if the device is connected?" Accordingly with android docs: "if you already hold a connection with a device, then performing discovery can significantly reduce the bandwidth available for the connection, so you should not perform discovery while connected."

Do you really need to perform an inquiry every 1 second? Will consume a lot of battery...

Since you need to perform the measure periodically, why not use AlarmManager or CountDownTimer?

In your specific case, I believe you should be using AlarmManager, since it can repeat indefinitely. If you want something to execute every second for 10 seconds, for example, use CountDownTimer.
