Hi guys, I have the RTK Postcard and Portability Shield combo. The NMEA output is logged to the SD card out of the box, but I want Rinex files instead. I want to use it for PPK in RTKLIB. The RTK Everywhere docs tells me to use u-blox software to change it , but I’m assuming that doesn’t work for Q…

Instead of logging NMEA, you can configure the module to output RAWX and SFRBX messages.

That’s incorrect for the LG290P used in the PostCard. The PostCard can save RTCM which you can later convert to RINEX format for PPP post-processing analysis.

Sorry, I think my first post might have been badly worded. I want to use my Postcard as a rover, logging RINEX (or smiliar) files to the SD card, then combining my rover RINEX file with observation files from a comercial 3rd party base station in RTKPOST. Using the serial terminal, I enabled the fo…

[image] mag: I also have troubles with the Postcard crashing and bootlooping, requiring me to power cycle it to make it work again. IMHO, You are asking the PostCard to do too much in “real-time” As a reference, below are the NMEA Settings that I use for the PostCard as a RTK Rover: 1) Mess…

Thanks @rftop ! I’ll try to fully disable NMEA messages later today to see if that helps. Did the selection of RTCM messages in the screenshot seem reasonable? Would changing the frequency make any difference to the results? I see the documentation says that the frequency is 1Hz in base mode becau…

I’m still getting NMEA messages in the SD card txt file, even though all NMEA messages are disabled. Any idea what I’m doing wrong? It’s less than before, but there still are NMEA messages mixed with the other binary data. convbin is still unable to read the file. [nmea off] NMEA messages at the…

This might be a quick check: Put the PostCard in Base Mode, and perform a quick survey. Check if your software workflow will convert the Base files to RINEX.

In base cast I am seeing same thing it records to a txt file and I’m on latest release client

Take a look at the 7th post here Postcard firmware update and assembly - #7 by sparky which has some notes (namely use base mode and RTK2go)
