Firmware for LC29(BA)

IoT Modules GNSS Module
1

I have Quectel LC29H(BA) GPS module firmware ver. LC29HBANR11A04S_CSA4,2024/02/28,18:04:54

I need to use this module in RTK rover mode but it gives only 3D fix and responds with error 3 when trying to enable rover mode through $PQTMCFGRCVRMODE,W,1 and even get info $PQTMCFGRCVRMODE,R gives error 3. Looks like something is disabled in firmware.

I kindly ask you to provide me appropriate firmware to use RTK capabilities of this module. Email aldis.pinkens@gmail.com

Dear support, can you help me to solve my problems?

It might be obvious but is the command complete?
Error 3 = Unsupported command…
try
$PAIR003*39 disable gnss
$PQTMVERNO*58
$PAIR514*3A Clear the current configuration and restore the default settings.
$PQTMRESTOREPAR*13 restore default
$PAIR513*3D save file system
$PQTMSAVEPAR*5A save parameters
$PAIR511*3F Save current navigation data from RTC RAM to flash
$PAIR023*3B → reboot
ask for a copy of fw and reflash.
here a tread:

on Version: 1.4
immagine
but on 1.3 This command is only supported on LC29H (DA, EA).
so ask for a new fw.

Hi Aldis,

The latest FW is sent to your email.

Thanks for your help! Yes, I enter full commands, including correct checksums. Just my module doesn’t accept several PQ commands, not only for writing but also for reading current status. The same time I can correctly read FW version PQTMVERNO so this confirms I’m doing everything right.
I will try new FW what support just sent me.

@June_Zhu I’m having roughly the same issue.. Can I get the Fw please as well?

thanks

Hi carlitos18,

Are you looking for 2-wheel or 4-wheel FW?

Thank you,
June

Hello,
Actually 4 Wheels

Hi carlitos18,

Hi carlitos18, have you upgraded your module with new FW? Do you have RTK fix?
I have no luck with it…

Hi Aldis,

Have you successfully set up the device as a rover? Were you able to obtain a position fix? Did you manage to get an RTK float?

Hi June!
I have successfully upgraded FW (now it is LC29HBANR11A05S_CSA4, 2024/12/11, 14:34:43) and also it is possible to change $PQTMCFGRCVRMODE,W,1 now.
I have succesfully connected to NTRIP caster, receiving some bytes from it as response to sent request. Satellite count is stable 25-30.
But still no signs of RTK, RTK float/RTK fix is 0.
I’m using QGNSS v.2.1.

14

which correction RTCM are you using?

15

You mean- what is format mount point use? It is RTCM3

16

RTCM ok, but which version MSM4 MSM7? For which constellation is the correction available and for which bands?

Hi @June_Zhu,
I’m experiencing the same issue with the GPS module running firmware version LC29HBANR11A04S_CSA4, 2024/02/28.

Could you please provide me with the firmware file as well?
I’m working on an autonomous marine vessel project and currently managing RTK functionality.

Also, I wanted to ask if it’s possible to perform the firmware upgrade remotely via a terminal interface (e.g., serial or SSH), since I don’t have access to any GUI tools for this operation.

Thank you in advance for your support.

Best regards,
Luigi

My caster http://91.216.2.20:5001/ gives me this mountpoint: SITE;RTCM 3;Nearest;2;GPS+GLO;LatPos;LV;0.00;0.00;1;0;Leica GNSS Spider;none;B;N;9600;

Hi Aldis,

I think there is something wrong with your caster. Is it for L1+L5? It supports the RTCM protocol which is in accordance with RTCM Standard 10403.3 Differential GNSS (Global Navigation Satellite Systems) Services - Version 3.
