1. The mark  means that the Part supports this mode.
2. In all-in-one solution, all PMTK commands used for the GNSS part should be sent through the GSM
UART after the GNSS part is powered on. Make sure the GSM UART Port is accessible.
3. In all-in-one solution, when the GSM part is in sleep mode, the GNSS part can work in either standby
or full on mode. However, if NMEA GPS data is needed, the GSM part should be woken up first and
then send the corresponding AT command to get. For detailed AT command information, please refer
to document [1].
4. In stand-alone solution, all PMTK commands used for the GNSS part or NMEA output can be sent or
received through GNSS UART port when the GSM part is powered on.
