Hi Destr,
Currently this is the latest firmware for LC29HBS. You already have it.
Best regards.
Hello. Please send me the firmware for the lc29hba module. Thank you.
Hi Antyk,
I will send you the latest LC29HBA firmware via message. Please kindly refer to it.
Best regards.
My LC29HBA board is not Floating either. My version is LC29HBANR11A01S_CSA4,2023/01/16,18:20:07*07 Please send me the complete version via email.
Hi,
I have two modules, one lC29HDA, and one LC29HBS module. I would like to implement an RTK system for a rover, using locally (through LORA communication) not using external servers, the corrections for the rover’s guidance.
How can I configure the LC29HDA for use with RTK from the lc29HBS?
Thank you.
Hi Sittipat Butcha,
From the GSA message, it seems that your test condition is not very good. You can turn on signal view and see the signal level. Please test RTK feature in open sky area.
Best regards.
Hi Julio Maragano,
Please make sure the distance between the rover station and the base station should not exceed 15 km, otherwise the accuracy of RTK cannot be guaranteed.
If you are building a private RTK network, with one or two base station, you can send base station data to rover through LORA module.
So the data stream should be: LC29HBS → base LoRa → rover LoRa → LC29HDA.
You need to set PQTMCFGSVIN on base station LC29HBS. Please mount base station in a clear open sky environment. So that base can get a accurate position.
If you don’t know the real coordinate of BS, please set it in Survey-in mode. After the survey-in duration, the coordinate of BS get fixed and never change (unless BS is moved, then you need to re-survey).
The longer duration time you set, the more accurate BS position you have. Recommended value: 43200 (seconds, equals to 12hours).
If you know the real coordinate of BS, you can convert it into ECEF format, and input it in the command.
Example:
Unknown coordinate: $PQTMCFGSVIN,W,1,43200,15.0,0,0,0*0D
known coordinate: $PQTMCFGSVIN,W,2,0,0,X,Y,Z*(checksum)
$PQTMSAVEPAR*5A → Saving configuration in flash.
I’m using an LC29H (BS) module and I can’t generate the 1005 packet in the GNSS with these settings from the image.
I followed all the commands in the image correctly, but it didn’t work.
I waited for more than 30 minutes for the 1005 packet, but it didn’t appear.
Without the 1005 packet, I won’t be able to make corrections on the LC29H (DA).
This is the firmware version:
$PQTMVERNO,LC29HBSNR11A01S,2023/02/13,10:14:06*27

From
has the $PQTMCFGSVIN,R*26 returned a valid xyz (ecef) position?
if so U must manually compile a valid fix position string e.g:
$PQTMCFGSVIN,W,2,0,0,X,Y,Z*checksumand before save can add also
$PAIR436,1*26If
$PQTMCFGSVIN,R*26 has all 0 then U can set a valid fix position also indegrees value e.g.
$PAIR604,1,1,24.7728165,121.0226365,175.01*32
save and ask if done by $PAIR605*39
