What is the relation between SLEEP_RQ pin and sleep mode AT code, do I need both to enter sleep mode?

            Yes, you need to first enable sleep mode on the endpoint using the command:
             
            ATSM1
             
            and then pull the SLEEP_RQ pin high to enter sleep. Pull the pin low to exit sleep mode.
