Perhaps I’m being a little stupid here but how do you save a changed parameter?
After changing a parameter I have this screen:
If I exit this screen the parameter is not saved and there’s no save or write button so is there some magic involved or secret trick to write a changed parameter?
While editing there’s a ‘Next’ button, not sure why, I don’t want to go to the next parameter, I just want to save/write the current one?
Press menu button
Must be going blind… 
now if only it worked?
I get “0 parameters written to drone”
you need to do some changes , did you change anything before sending?
Yes, I changed the value of RATE_YAW_P from 0.25 to 0.20. The numbers do not go green as in the screenshot unless the value has changed.
It writes fine with MP but won’t write with Droidplanner2.
ok, this sounds kind of familiar, but at the same time I know I’ve done it before. unless it’s a new bug…
just for good measure, try to select another parameter after editing - and consider reporting it as an issue in droidplanner’s git.
