I have followed the directions from the site below for bluetooth comm between an Arduino board using the HC-05 and an smartphone. It works fine.
The problem is that I need to measure the RSSI from my phone and using the command
AT+INQ the response from the HC-05 is "OK" and nothing else.
I paired both devices using my phone as master and the HC-05 as slave, and when I am sending commands to the HC-05 through the Arduino, the pin KEY from the HC-05 is set to high (3.3V).
Do you have any suggestion to solve the problem I am facing?
