Hi,
I'm attaching a M8T module to teensy 3.1 (arduino like board) via UART 1. It is configured to provide
raw data measurements with GPS + GLONASS and save it to a file .ubx.
Everything is alright with the process of configuring the module with Arduino IDE.
The problem comes when a run the .ubx file through rtkconv. I only get the .nav.
But I'm only interest in the .obs.
Does anyone is having the same problem?
I get the E=275 error. Couldn't find a reference anywhere.

Thanks on reply Marina!
In the meanwhile, I downloaded Demo5 version of RTKLib and everything passed well.
Anyway I am not skilled enough to enter inside code nor to compile it by myself.
God bless You Marina

Hi!!
I solved this by setting a loop in my code to collect GNSS data for one second.
String dataStringGNSS = ""; //aux string to print on datalogger
char inByte; //aux char
int start = millis(); // variable to count milli seconds
while (millis() - start < 1000) // 1 second loop
{
if(gpsSerial.available() > 0){
inByte = gpsSerial.read(); //UART reads byte by byte
dataStringGNSS = String(inByte); //typecast byte into string
dataFileGNSS.print(dataStringGNSS); // saves on datalogger
}
}
Same problem like Marina had 3 years ago...
RTKConv.exe doesn't bulit OBS file, while ConvBin.exe does it but regardless to entered start time it produces RINEX with wrong date: 2019/04/16 (tomorrow) instead 2019/04/09 (last tuesday when actual observations were taken)
Btw. I'm working with DJI Phanton 4 RTK and during last few months everything has been passing well...
Tnx. & if somebody is interested there are two files attached below: single flight file and VRS rinex in ZIP for PPK
100_0536_PPKRAW.bin

Hi,
You can try to use TEQC like this : teqc loggps1_3.ubx > loggps1_3.obs

Hi!
Thanks for the tip. But apparently there's something else.
I'm starting to wonder if Arduino IDE is not modifying the data somehow while it prints to the file. Or if the microprocessor is modifying the data as well. Putting in a format that neither Teqc or RTKLIB can understand. 'Cause if I collect the data using U-Center, my configuration works just fine and I can get the .obs from RTKLIB.

Hi,
Which kind of ublox GNSS module are you using ?
When you do "teqc loggps1_3.ubx > log.obs" what do you get into the file "log.obs" ? Nothing ?

M8T module.
I get blank file...
