4.10.2.3 S24, Set Number of Seconds Delay Before g20 Enters Sleep Mode
This command activates/disables the Sleep mode. The terminal sends ATS24=5, and if there are no radio and UART activities,
the g20 enters sleep mode in 5 seconds.
If terminal has some indication of the CTS pin activity, it can see:
• If +MSCTS=0 (default), the line changes its state periodically. (For more information refer to “+MSCTS, Enable/Disable
CTS During Wakeup Period” on page 195.)
• If +MSCTS=1, the line is switched off at the moment of entering Sleep mode and stays off even if g20 is awakened.
Set Command
The Set command sets the amount of time, in seconds, the g20 should wait before entering Sleep mode.
