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