LC29H (BS) setup

[Vasi]

It is normal for the BS module to look like this?

It dose not get the location information.

I set up to get the base station location in 3 seconds just for debugging using this comand

$PQTMCFGSVIN,1,300,15,0,0,068
$PQTMSAVEPAR5A

Does anyone have any ideea how to set up this base station when you don’t know the fixt position. I need to feed the correction information to an Ardusimple [WiFi NTRIP Master] ESP32 XBee and then to rtk2go. Thanks

Hi @Vasi

1. The phenomenon shown in the figure is normal.
2. Send the command “$PQTMCFGSVIN,W,1,300,15,0,0,0*15” to configure the Survey-in mode. After positioning, when the 3D threshold is less than 15 and the cumulative count is 300 times, the Survey-in is completed.
   Send the command “$PQTMSAVEPAR*5A” to save the Survey-in configuration command.
3. Send the command “$PQTMCFGMSGRATE,W,PQTMSVINSTATUS,1,1*58” //Open PQTMSVINSTATUS and check the convergence status of Survey-in.
   The command format is shown in the figure.
   When the <Obs> value is equal to <CfgDur>, it means that Survey-in is completed.
   
   
4. When Survey-in is completed, you can send the command “$PQTMCFGMSGRATE,W,PQTMSVINSTATUS,0,1*59” to close PQTMSVINSTATUS message.

Why isnt ntrip caster available in the app?
When do i know that the suvey is complete to close it and save it.
Thanks George for your help

I\ve closed the survey with the “$PQTMCFGMSGRATE,W,PQTMSVINSTATUS,0,1*59” command and the data dok isn’t populate with latitude and longitude and the Ntrip server isnt availabe

Hi Vasi, read here: https://www.waveshare.com/wiki/LC29H(XX)_GPS/RTK_HAT#RTK_Base
You have done the Survey-In observation but for a good position need at least 24h = 86400s …however did
$PQTMCFGSVIN,W,1,3600,15,0,0,0*15
then
$PQTMCFGMSGRATE,W,PQTMSVINSTATUS,1,1*58 but before apply
$PQTMCFGMSGRATE,W,PQTMSVINSTATUS,0,1*59 note the ecef value and then appy for close…
see also $PQTMCFGSVIN,R*26 before close, that indicate the last value if all done 86400…
now close ($PQTMCFGMSGRATE,W,PQTMSVINSTATUS,0,1*59) then apply
$PQTMSAVEPAR*5A
reboot PAIR023*3B
set fixed base in ecef e.g.
$PQTMCFGSVIN,W,2,0,0,4013185.2205, 1748875.1673,4623656.6043*24
continue with rtklib “strsvr” …
