Include some sort of provision for setting/enabling/disabling alarms via AT+ commands.
Probably something like
AT+ALARM0EN // Enable alarm0
AT+ALARM0SET124500 // Set alarm0 to 12:45:00
AT+ALARM0DIS // Disable alarm0
AT+ALARM0 // Print alarm0 time and status
AT+ALARM // Print all time and status for all alarms
Include some sort of provision for setting/enabling/disabling alarms via AT+ commands.
Probably something like
3 alarms (alarm0/1/2) should be enough.
Will change current
AT+ALARM
code toAT+BUZZER
Will also need to increase command buffer sizes.
