All-in-one
solution, make sure the GNSS part is powered on before sending these PMTK commands.
3.21. LOCUS
MC60 supports the embedded logger function called LOCUS. When enabled by PMTK command
―$PMTK185, 0*22‖, the function allows the module to log GNSS data to internal flash memory
automatically without the need to wake up host, and thus, the module can enter into Sleep mode to save
power consumption, and does not need to receive NMEA information all the time. MC60 provides a log
capacity of more than 16 hours.
The detail procedures of this function are illustrated below:
The module has fixed the position (only effective in 3D_fixed scenario).
Sending PMTK command ―$PMTK184,1*22‖ to erase internal flash.
Sending PMTK command ―$PMTK185,0*22‖ to start logging.
The module logs the basic information (UTC time, latitude, longitude and height) every 15 seconds to
internal flash memory.
Stop logging the information by sending PMTK command
―$PMTK185,1*23‖.
MCU can get the data by sending PMTK command
―$PMTK622,1*29‖ to the module.
PMTK C
ommand ―$PMTK183*38‖ can be used to query the state of LOCUS.
The raw data which MCU gets has to be parsed via LOCUS parser code provided by Quectel. For more
details, please contact Quectel technical supports.
