Beginner Help with PyMAVlink and Mission Planner Commands for Serial Communication

[Jamie S]

Hello!

I am new to pymavlink and am trying to develop a python3 serial communication script to send messages to Mission Planner.

I have tried reading these documents which I generally have found unhelpful and non-descriptive.

https://www.samba.org/tridge/UAV/pymavlink/apidocs/mavlink.html

https://mavlink.io/en/messages/common.html

I am wondering if someone could help point me to python3 resources or help me get started with basic messaging?

This is my basic code so far:

from pymavlink import mavutil

connection = mavutil.mavlink_connection(IP_address)

connection.wait_heartbeat()

print("Heartbeat from system (system %u component %u)" % (connection .target_system, connection.target_component))

connection.mav.send('this is a test')

connection.close()

Hi Jamie

The absolute best place IMO to get Pymavlink support is the gitter channel: https://gitter.im/ArduPilot/pymavlink

A basic introduction can be found here: https://mavlink.io/en/mavgen_python/

However the best place for Pymavlink docs is IMO https://www.ardusub.com/developers/pymavlink.html

Hope that helps.

Regards
