14 Commands for Hardware Control

This chapter describes the AT commands that operate the hardware.

14.1 AT+CALA

The AT+CALA command sets the alarm time on the ME. When the set alarm time is reached, the alarm sends a URC, and the alarm time is reset to "00/01/01,00:00:00".

The alarm provides two functions:

zTimed notification SM: When the module is not powered off, a timed SM can be unsolicitedly reported through +CALA.

zClock mode: When the module is powered off, the clock function can be used to wake up the module. When the module is powered off, and the set alarm time is reached, the module is waken up, and the +CALA is unsolicitedly reported.
