Dear Sir

After obtaining the effective satellite time information, the module’s NMEA sentence is output in whole seconds by default.
The output sentence can be configured through the $PSTMCFGMSGL instruction.

Best Regards

Any possible command( not GETRTCTIME ) to milliseconds timestamp given…

and add other command not in two list
example get RTC Time in NMEA command output but not in a list?

Dear Sir

The update rate can support up to 10Hz. For details, please refer to the $PSTMCFGTDATA command.

Any possible command( not GETRTCTIME ) to milliseconds timestamp given…
——No.

If you set a 10Hz update rate, the NMEA time will be output at 10Hz.

Best Regards

Okay Sir, and I changed NMEA Output response message list ,
$PSTMCFGMSGL,0,1,40,0
That means, i need only RMC packet . but unfortunately whenever this command given it given one time only, this command does not save into nv backup memory…
I need only this response command remaining not all required…
L89 module how to save configurations in backup memory ?

Above command $PSTMCFGTDATA not listed in L89 module GNSS protocol document…

Dear Sir

The configuration can be saved through the $PSTMSAVEPAR command.
Please refer to the attached protocol document.
