How can I convert files on the .ubx format to .obs RINEX?

I'm using rtklib and teqc to try and get the files on RINEX format, but all I get are blank .obs and .nav files.

Please advise what version of u-blox receiver you are using.

You may want to disable all other messages produced by the receiver and ensure that RXM-RAWX messages are enabled - you should be getting continuous stream of messages with B5 62 02 15 header.

u-blox does not provide conversion software.

The following software was given a good review by u-blox customers:
TEQC: http://facility.unavco.org/software/teqc/teqc.html
Novatel - Waypoint: http://www.novatel.com/products/waypoint_pps.htm

You may want to check with RTKLIB and TEQC to make sure they can support multi GNSS messages from u-blox M8 receivers.

as I understand, currently TEQC doesn't support RXM-RAWX messages, but only RXM-RAW

rtklib includes 'convbin' and 'rtkconv' tools for converting .UBX logs to RINEX.

This link https://wiki.openstreetmap.org/wiki/RTKLIB provides more information.

I also want to use RTKLIBS tool RTKCONV for postprocessing. I had some success converting a .ubx File to a .obs and .nav and .sbas file using RTKCONV. Therefore I did the following (I have ublox Neo-M8T receiver)

I enabled RXM-RAWX, RXM-SFRBX, AND RXM-MEASX only if I also enabled RXM-MEASX I was RTKCONV was able to convert the .ubx file before I did not manage it.

However I also tried with RXM-RAWX, RXM-SFRBX, AND RXM-MEASX enabled to log the data and then retrieve this .ubx file and convert it to a .obs and .nav file using RTKCONV but it did not work any suggestions why?

I also did not figure out why RTKCONV is not able to convert my .ubx file if I have just RXM-RAWX message enabled.
