Hi Guys,

Need help, This magnetometer inbuilt in NEO 7M GPS module is acting crazy.

Have a look at video and please help me fix this issue. I am out of ideas.





Thanks!

Hi
Can you describe a little more, like what Flight controller you using?

The GPS comes with a case, check if the solder on the gps is lose or shorting some where.

omnibus f4 pro

gps comes with case, tried with or without case. only way to get it to work is by holding wire only.

all solders are rechecked but i can resolder again if needed.

You can do a continuity check to see if there is any shorts between the terminals

no lose solder point. It needed pull up register on sda and scl. That's it.

Thank you

Yes, one pull-up resistor each to vcc on sda and scl solved the problem.
