Hi all.
I have downloaded the 3.2.1 version of ardupilot code and compiled in the modified Arduino IDE for Ardupilot.
However, when I try to execute a code from sensors library, AP_Compass_test, for exemple, I get strange data on the Serial Monitor.
If that is the data stream from the com port then you are looking at MavLink data stream which is not readable as text.
This is why the terminal function was removed from recent GCS’s.
Try running a GCS and see if it is interpreted correctly.
