In sleep mode, the module enters a low power consumption state. In this state, the radio frequency (RF) is

functioning properly but the peripheral interface of the module is disabled. The module will exit the sleep mode when

there is an incoming call or SMS message, and will re-enter the sleep mode at the end of the incoming call or

conversation.
