22.15.1Description
Enables/disables the storing of the last value of NMEA $GSA messages, and gets the current messaging
state. If <state> parameter is enabled, the last value of NMEA $GSA messages can be retrieved with the read
command even when the GNSS is switched off.
The NMEA $GSA messages are volatile.

22.16.1Description
Requests cellular module to provide the location data; the location can be determined using:
• GNSS receiver
• CellLocate
®
(location based on network cells data)
• Combination of both technologies (hybrid)
The final result code indicates if sending the command request to the localization information process was
successful or not. The URC is issued to provide the requested information via +ULOC set command.
The GNSS interface and CellLocate
®
can be used at the same time: if the GNSS sensor is reserved to another
interface an error result code is provided ("+CME ERROR: GPS busy" if +CMEE=2).
It is possible to configure the Hybrid Positioning through +ULOCGNSS and +ULOCCELL AT commands even if
it is running: the parameters are stored in NVM and will be applied at the next +ULOC command.
