Magnetic interference

[xman4242]

I am having a somewhat unique problem. I am getting magnetic interference mornings on a brand new solo and it will not let me fly. I cannot figure out what could possibly be interfering. We do have an in ground dog fence. Could that he it? I also tried calibrating the compass manually and the little green bar on the top of the screen will not go more than halfway across no matter what I do. Any advice? Thanks in advance!

Is it just a morning thing? Any other time of the day?

First thought, condensation...dew...humidity

Lol Im pretty sure he meant "warnings"

 

[xman4242]

I did mean warnings

 

[xman4242]

Turned off the fence no luck. We do have underground power lines as well. Is that a problem?

 

[RichWest]

I was thinking, wh-what....

You could just have a bad compass connection, check your plug under the battery tray. Otherwise maybe bad compass, $10 from BH...

 

[xman4242]

So pull out the battery, and unscrew the screws directly beneath it?

 

[RichWest]

That's were the compass plug is located, I believe off the #4 arm...

 

[xman4242]

The plug was ok. I still have the warning. Would a factory reset help? In the app, it shows solo is facing the opposite direction that it really is.

Put up with that for 10 days. If I waited long enough it would clear. Swapping in a new compass in the leg fixed it immediately and hasn't come back.
$13 for me with shipping. Adding an extended controller battery (highly recommend) for $20 gives me free shipping.

Thanks for the help so far. It will say searching for GPS, stabilize, then fly, then magnetic interference right one after the other. Any ideas?

 

[xman4242]

I might just order another leg... Sounds like a good plan right now

 

[RichWest]

Possibly the compass is installed backwards, the flat side out is correct, pull the leg extension to reveal fully.

 

[xman4242]

Compass is installed correctly.

Good news and bad news. Good news is, I appear to have fixed it.
Bad news, I am not really sure how it happened. I played with the battery while it was out of the solo. I put it back in and yay! No more warning! (Although I am indoors)

 

[xman4242]

The problem is back.

 

[XevetS]

open up mission planner connect the solo and turn off the leg compass and restart solo, see if the problem persists if not its the leg compass,

 

[xman4242]

How exactly do I do that? What parameter?

 

[DaveB]

Go for the new compass we are getting "OLDER" every day. Go fly,have fun.

Are you familiar with Mission Planner or the Tower app? Last thing I an suggest to try before replacing the compass is doing a parameter reset on the Pixhawk.
