What Arduino library to use for simpleRTK2+heading to retrieve heading/direction in Moving Baseline mode?
A starting point is a UBX parser, the rest of the work you will have to write it: https://github.com/ardusimple
I need to get heading//steering information for my Arduino/ESP32 project.
How san I use Matlab files for that
You can record a logfile with Windows tool u-center. From there you can export to tables de values or process directly from Matlab if you implement a UBX parser.
