Hello, i have 2 doubts regarding in L89 module.

By default NMEA protocol version was :Format for NMEA 0183 Rev 3.01
but how will changes to latest : Format for NMEA 0183 Rev 4.10

And PSTMPPS command behavior does not understand properly, understand duration command only.
can anyone give exact information/ purpose of this above command…

Dear Sir
Sorry for the late reply.
Please refer to the following commands:
$PSTMSETPAR,1122,0x04 //Set the NMEA version to 4.1
$PSTMSETPAR,1122,0x0c //Set the NMEA version to 3.01 (default)

For PSTMPPS, please refer to the example of the protocol document, as shown in the figure below.

And i using
$PSTMSETCONSTMASK,1
$PSTMCFGCONST,2,0,0,0,0,0
$PSTMSAVEPAR
After valid GPRMC packets, Constellation mask changes to IRNSS, GPS not settled constantly.
But both GPS + IRNSS
$PSTMSETCONSTMASK,1025
$PSTMCFGCONST,2,0,0,0,0,2
$PSTMSAVEPAR
this above configuration was success , still same on after reset also…

How to set fixed constellation mask… even module reset also not backs to default one…

Dear Sir

After the configuration is saved through the PSTMSAVEPAR commands, the module restart will not restore the default.
Please provide log for check.

Dear Sir

I used the command you sent above to test, but there is no phenomenon of restoring the default.
So, please help provide the firmware version you tested (it will be output when power on) and test log.

Best Regards
