21.1 AT+CGPS Start/stop GPS session
Description
The command is used to start or stop GPS session.
NOTE 1. Output of NMEA sentences is automatic; no control via AT commands is provided. You
can configure NMEA or UART port for output by using AT+CGPSSWITCH. At present
only support standalone mode. If executing AT+CGPS=1, the GPS session will choose cold
or hot start automatically.
2. UE-based and UE-assisted mode depends on URL (AT+CGPSURL) and certificate
(AT+CGPSSSL). When UE-based mode failing, it will switch standalone mode.
3. UE-assisted mode is single fix. Standalone and UE-based mode is consecutive fix.
4. After close GPS, need to wait about 2s~30s for next start. Reason:If the signal
conditions are right (strong enough signals to allow ephemeris demodulation) or
ephemeris demodulation is on going, sometimes MGP will stay on longer in order to
demodulate more ephemeris. This will help the engine provide faster TTFF and
possibly better yield later (up to 2 hours), because it has the benefit of more ephemeris
