Changing MC25 GNSS Settings like Elevation Angle, SBAS, Static NAV Threshold etc

hi

I am using Quectel’s MC25-MB Module for my GNSS Trackers in India.
Can you share with me the latest Firmware Available for MC25MB Module

also while testing, i see that the device drifts in cities with high rise buildings or bridges?

also check that can be fixed by changing angle of elevation or the elevation mask

But are AT HEX Commands supported in MC25MB

16:32:16.765 → AT+QGNSSCMD=?
16:32:16.812 → +QGNSSCMD: (0,1),“cmdString”
16:32:16.812 →
16:32:16.812 → OK

But all the commands that i try return 7101
4:43
16:32:42.064 → AT+QGNSSCMD=0,“$CCDFT,0*66”
16:32:42.096 → +CME ERROR: 7101

Tried multiple HEX commands,

AT+QGNSSCMD=0,“BACE000001000401”
AT+QGNSSCMD=1,“BACE000001010702”

In both the above cases got following logs,
AT CMD0 line: AT+QGNSSCMD=1,“BACE000001010702”
AT CMD parse start cmd len=9: +QGNSSCMD
AT CMD parse set cmd type=0
AT CMD parse push param type=4 len=1: 1
AT CMD parse push param type=2 len=18: “BACE000001010702”
AT CMD0 run +QGNSSCMD type=0 param=1,“BACE000001010702”
[AT]>>“QGNSSCMD Param->iType 0”
[AT]>>“QGNSSCMD HEX CMD Error2!”
AT CMD0 CME error code=7101

I have already checked following,

  1. GNSS Engine is ON
  2. Device in All-in-one mode
  3. Document confirms Protocols are working.

Could this be related to little-endian format?
what could be the issue?
