I have tried setting up the LC29H EA module as a base station, following these steps: ’ LC29H (EA) RTCM3 out? '. Below is a list of the responses for each step.

[Uart Tx:0015 B] $PQTMVERNO58
[Uart Rx:0055 B] $PQTMVERNO,LC29HEANR11A04S_RSA,2025/04/02,15:51:162D

[Uart Tx:0020 B] $PQTMRESTOREPAR13 RESTEAR PARAMETROS
[Uart Rx:0023 B] $PQTMRESTOREPAR,OK3B

[Uart Tx:0025 B] $PQTMCFGRCVRMODE,W,229 MODO BASE
[Uart Rx:0024 B] $PQTMCFGRCVRMODE,OK64

[Uart Tx:0017 B] $PQTMSAVEPAR5A GUARDAR PÀRAMETROS
[Uart Rx:0020 B] $PQTMSAVEPAR,OK72

[Uart Tx:0015 B] $PAIR432,122 RTCM MSM7
[Uart Rx:0019 B] $PAIR001,432,23C COMMAND SENDING FAILED

[Uart Tx:0015 B] $PAIR432,023 RTCM MSM4
[Uart Rx:0019 B] $PAIR001,432,23C COMMAND SENDING FAILED

[Uart Tx:0015 B] $PAIR434,1*24 NO RESPONSE

[Uart Tx:0018 B] $PAIR062,0,010F ENABLE NMEA GGA reSPONSE
[Uart Rx:0019 B] $PAIR001,062,03F

After this, it doesn’t send RAW data to function as a base; when I connect to it, it only displays the firmware version, and then both the USB and UART ports go silent.

[Uart Tx:0015 B] $PQTMVERNO*58
[Uart Rx:0073 B] ¡!I!!cŒBÀB‚Œ!䵧ä$PQTMVERNO,LC29HEANR11A04S_RSA,2025/04/02,15,

i do not know where is the problem, i have the correct version of firmware? , i need otyher, is corrupt my firmware?

Hola,Mario

after sent savepar U must reboot (or power off) the module…

The complete list:

$PAIR382,1*2E → Test command for lock system sleep enabled
$PAIR003*39 → power off GNSS system
$PAIR514*3A  Clear the current configuration and restore the default settings set via $PAIR
$PAIR512*3C  clear all data
$PQTMRESTOREPAR*13 # restore $PQTM params to default
$PQTMSAVEPAR*5A
$PAIR023*3B   reboot  module
$PQTMGNSSSTOP*09  same of power off GNSS system
$PQTMCFGRCVRMODE,W,2*29   # set receiver to base mode
$PQTMSAVEPAR*5A
$PAIR023*3B   reboot  module
```now the module spits rtcm msm4 and 1005
for check if in base mode ask `$PQTMCFGRCVRMODE,R*32`  reply `$PQTMCFGRCVRMODE,OK,2*7A`

$PAIR023*3B   reboot  module
Set the Survey-In observation  **only one** of these:
PQTMCFGSVIN,W,1,300,15,0,0,0*15
$PQTMCFGSVIN,W,1,3600,15,0,0,0*23
$PQTMCFGSVIN,W,1,3600,1,0,0,0*16
$PQTMCFGSVIN,W,1,1200,15,0,0,0*25
$PQTMCFGSVIN,W,1,1200,1,0,0,0*10
$PQTMCFGSVIN,W,1,60,2,0,0,0*16
$PQTMSAVEPAR*5A

$PQTMSAVEPAR*5A

now look at $PQTMCFGSVIN,OK*70

Get confirm of command sent $PQTMCFGSVIN,R*26
Look at $PQTMCFGSVIN,OK,1,3600,15.0
Enable the Survey-In observation results
$PQTMCFGMSGRATE,W,PQTMSVINSTATUS,1,1*58
Look at survey-in mean position accuracy in metres/meters
$PQTMSVINSTATUS,1,383462000.0,2,55,1,0,X.8019,Y.8467,Z.4197,||this one 0.1108||*0D

Disable the Survey-In observation results
$PQTMCFGMSGRATE,W,PQTMSVINSTATUS,0,1*59*

If U want to fix the base manually:
#Set *the base in ecef $PQTMCFGSVIN,W,2,0,0,X,Y,Z*checksum

example: PQTMCFGSVIN,W,2,0,0,X704517.8019,Y298190.8467,Z093137.4197*64

or in decimal degrees:
$PAIR604,<Enable>,<Mode>,<Para1>,<Para2>,<Para3>*CS fix pos.

$PAIR604,1,1,40.xx617558,15.xx648938,300.540*38

$PQTMGNSSSTOP*09
$PQTMCFGSVIN,R*26 check if ecef base is done corrected

$PAIR434,1*24 ==> set RTCM3.x output with message type 1005
$PAIR436,1*26 ==> set RTCM3.x output with satellite ephemeris
$PAIR432,1*22 ==> set RTCM3.x output with type MSM7
$PQTMSAVEPAR*5A
$PAIR023*3B

Hi @Griyao based on the log, seems you did not reboot the module after change the Rover mode to Base Station Mode.

Summary of Correct Steps

  1. Restore Parameter: $PQTMRESTOREPAR*13.
  2. Save: $PQTMSAVEPAR*5A .
  3. Switch Mode: $PQTMCFGRCVRMODE,W,2*29 .
  4. Save: $PQTMSAVEPAR*5A .
  5. Restart: $PQTMSRR*4B (Essential for mode change).
  6. Configure Survey-In: $PQTMCFGSVIN,W,1,3600,1.2,0,0,0*0A (1 hour/1.2m accuracy).
  7. Save & Restart Again: For Survey-in to begin.
  8. Verify: Use the QGNSS tool to monitor the binary output. Ensure the antenna is in a clear, open-sky environment to achieve the required 3D fix for the survey to start.

Best Regards.

i have reset the module, warm, cold, and power off wait for seconds, minutes, and th last reset is power of an 12 hours power on for work, and surprise now is working fine, thanks for help, many many thanks. now the caster is working.

best regards
