MavLink for 3rd party apps

[edasque]

Is it possible for an app to listen (and maybe transmit) to MavLink via APM Planner? I'd love to write a small app that does independent logging and processing of the data. I guess I would need APM Planner to act as a one way (read) or two way funnel/proxy.

Does that exist in APM Planner?

You can write Python scripts in Mission Planner, which read/write MAVLink. Does that suffice?

So they act as a plug in of sorts? I'll try it out (looking at http://copter.ardupilot.com/wiki/common-using-python-scripts-in-mission-planner/)

Use MAVProxy?

APM Planner can resend data received to second client. This was to support an antenna tracking device. I'll take a look to see what needs to happen to make it operational again.

@proficnc, wouldn't MAV proxy introduce potential delay and a failure plan since it needs to sit between the device and APM Planner?

@billbonney this would be helpful, thank you.

I am hoping to write this app in node.js using the mavlink module. If that's not possible, I would learn enough python to write it as an plugin running within APM.

@proficnc , @billbonney any help?

[proficnc]

The delay on a local machine isn't too long, I suppose it would depend on what you are doing with it

[edasque]

So both apps would talk to mavproxy including apm planner and mavproxy would talk to the radio?

[proficnc]

That's one method :) and Bill mentioned that APM Planner could also act as a proxy, so you have two options.
