Read data of Depth/Pressure Sensor

Sorry for the insistence but,
I install MAVProxy and I do:

$ mavproxy.py
Connect 0.0.0.0:14550 source_system=255
Failed to load module: No module named adsb. Use ‘set moddebug 3’ in the MAVProxy console to enable traceback

and it not show me anything.

With:

MANUAL> module load console
MANUAL> Loaded module console

Show the console, but the altitude not change:

I found this:
http://ardupilot.github.io/MAVProxy/html/development/mavcustmod.html

And I know that Global position is in:
https://pixhawk.ethz.ch/mavlink/#GLOBAL_POSITION_INT

I see that exists modules here of mavproxy:

But I still I continue without make the mental connections, I still cannot see how mix all.
I don’t find examples or manuals that show how make this from zero thinking that I need get the telemetry. I know to program in Python, but not find the API documentation about How make things.
Greetings!

Antonio,

Do you have an external pressure sensor connected to the Pixhawk? The altitude changes according to the pressure sensor reading.

MAVProxy is an open-source development tool, and the documentation is sparse. The best way to learn how it works is to read the source code and experiment.

Jacob,

How is good value for internal pressure Alarm?
