This chapter describes the AT commands for controlling the status of the module.

3.1 AT+CMER - Command for Setting Event Reporting

The AT+CMER command controls the +CIEV unsolicited reporting that is related to AT^SIND and AT+CIND commands. For an event that is registered through AT^SIND and AT+CIND commands, if the indicator value related to the event changes, unsolicited reporting is performed.
