Is there a way to get message from pixhawk when it reaches at the waypoin assigned by mission planner?

I want to get message from pixhawk when it reaches at a waypoint assigned by mission planner.
Is it possible?

There’s probably some boolean value in the source code of the autopilot. Then you can write code that utilizes a twilio server that says if landed = True, send message or something like that.

If you’re using mission planner, you are probably using ArduPilot and you might want to ask your question in discuss.ardupilot.org. This forum is for PX4.
