I got a Problem with my APM.
Since a couple of days the barAlt-Value raises and falls without an end.
When I put the APM on the desk and connect battery or usb, the altitude decreases or increases.
There is no difference if the GPS is connected or not.
In CLI baro test, the temperature value is very low an it's raising in little steps.
I reset the parameters, erased the eprom an re-installed the firmware(3.1.4 - 3.2.0rc3) with no effect.
The barometer is also covered with foam.
I am running out of Ideas. Is the sensor bad? Can anybody help?
