Abnormality in calculating signal strength using HC05

I use the following 2 commands to calculate the rssi value:

  1. AT+INQM=1,9,48
  2. AT+INQ

Whenever I ask my phone's bluetooth to get all the all the available devices and write these codes (in the serial monitor), HC-05 returns me the rssi value
else it either gives error[0] or just returns an OK.
How to resolve this, I want it to return me the RSSI everytime
thanks in advanced
