Compass Error

Shaff 67 · Jan 23, 2018

Need help, I was getting magnetic interference, tried everything, read on here and elsewhere until my eyes fell out.. So I gambled and replaced #4 leg, fired it up, no problem, flew 2-3 times after install.. Fire it up today and now it's compass error, for the life of me, I can't get it to accept a compass calibration. *Note* This unit was stored before and after on a 3/4" plywood table with a steel frame inside of a framed room in a metal building... FYI, this is our first drone, please be kind and keep the "what a dope" comments to a minimum, because, well, I know.......

Also< I have Tower if anyone can help me nav through it to maybe narrow down which compass might be defective..

Thanks for ANY help

Try a parameter reset. My favorite is the MREV. Method.

Shaff 67 · Jan 23, 2018

I'm in parameters, I cant find reset in the parameters

Or mrev for that matters

SYSID_SW_MREV set it to 0 it will be at 120 make sure you write parameters and reset the drone,
you will have to do a level and compass calibration afterwards and reset all the sliders in the solo app

Haven't done it in a while, but here are the steps:

1 Launch Tower
2 Open the menu and go to Parameters
3 Search for the SYSID_SW_MREV parameter
4 Change the value to "0"
5 Go to the upper-right part of the screen and select the three dot icon
6 Select Upload Parameters
7 Turn off your Solo and then turn it back on
8 Complete both level and compass calibrations
9 Reset all vehicle settings as they will have been restored to the default (speed and RTL settings)

Thanks, I'll try it again.. Do you need a door weight??? lol

Same, would a factory reset be recommended?

Shaff 67 · Jan 23, 2018

Just Bruce recommended a parameter reset (mrev) where is this?

MREV is the parameter reset - just follow the steps in my post above. Be sure to reboot the Solo after each calibration - level and compass calibration.

Thanks, I'll try that this afternoon

If you still have the problem "SPANK THE SOLO" yes give it a good 3 slaps on the Equp. bay. If still no help, change out the Pixhawk. (if you don't have a spare I'll send you one to try) you can also use MP to isolate each compass

Thanks Dave, I was afraid DHR was going to be called on me because of the a$$ whippings it had already gotten!! It appears to be be fine now after going thru all of the cals.. I appreciate the offer!!
