GNSS activity during sleep

Global Navigation Satellite System (GNSS) can interrupt and resume an ongoing sleep.

The following command example subscribes sleep notifications with a 5000 ms prewarning and a 60000 ms threshold:

AT%XMODEMSLEEP=1,5000,60000
OK

The following command example activates the modem:

AT+CFUN=1
OK

The following notification example indicates that the modem sleeps for 120 seconds due to Extended Discontinuous Reception (eDRX):

%XMODEMSLEEP: 2,120000

The following notification example indicates that GNSS activity interrupts sleep:

%XMODEMSLEEP: 5,0

The following notification example indicates that sleep is resumed after GNSS activity and that the remaining sleep period is 70 seconds:

%XMODEMSLEEP: 6,70000

The following notification example indicates that GNSS activity interrupts sleep:

%XMODEMSLEEP: 5,0

The following notification example is a prewarning of the end of the sleep 5000 ms before the sleep ends:

%XMODEMSLEEP: 2,5000

The following notification example indicates that sleep is resumed and that the remaining sleep period is 2 seconds:

%XMODEMSLEEP: 6,2000

The following notification example indicates that the modem sleep has ended:

%XMODEMSLEEP: 2,0
