If you go to the full parameter tree (at the bottom) in QGC there’s an option under tools to refresh all params. The parameter value is also saved in the log. Click on parameters on this page - http://logs.uaventure.com/view/Y6Ykxoto7uDJZPqUrQJse7
I would also recommend to do a full parameter reset after each update. I had many issues with parameters before and resetting them and recalibrating the sensors almost always fixed my problems.
Where are the parameters saved on the platform? Is there a text file or something? I’m building multiple units and want to easily save the parameters of each unit for reference and QA. Prefer not to do it through QGC but through ssh or something similar.
