How to load parameters

[Paul Carff]

I want to fly the sentinel indoors in my warehouse. I figure I need to change some params in QGC, not sure how to do that using the GitLab data:
https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-px4-params/-/tree/master

Is there a procedure for house to use these param files? Will this over write only the params in the file?

@Paul-Carff Yes, you would use the load from file option. Only the parameters in the file will be touched. All other parameters will remain the same. PX4 has defaults for all of the parameters built into the actual software image. When you start modifying parameters (changing them from their default values) PX4 will store those new values in the file /data/px4/param/parameters. So, for example, if you calibrate the magnetometer, the calibration parameters will be put into that file. You can always start from scratch by deleting that file and restarting PX4.

Thanks for the confirmation.

Where is the best place to learn about all of the parameters and their meaning/use?

@Paul-Carff I have upgraded to voxl2_sdk1.0.0 onto my Sentinel.

I believe this SDK uses px4 version is 1.14 Should I be using the v1.14 params now?

[Eric Katzfey]

@Paul-Carff Yep, use 1.14 parameters for SDK 1.0.0.
