What is DroneKit Python?
DroneKit-Python (formerly DroneAPI-Python) contains the python language implementation of DroneKit. The API allows developers to create Python apps that communicate with vehicles over MAVLink. It can also be used for ground station apps, communicating with vehicles over a higher latency RF-link.
What is Mavsdk?
MAVSDK is a collection of libraries for various programming languages to interface with MAVLink systems such as drones, cameras or ground systems. The libraries can be used onboard a drone on a companion computer or on the ground for a ground station or mobile device.

How does the heartbeat message work in MAVLink?
Once a connection is opened each device (aka “System”) sends the HEARTBEAT message at 1hz The ground station or companion computer requests the data it wants (and the rate) by sending messages of the following types Ground station or companion computer send commands to the vehicle.
How to add a new message to MavProxy?
Mavproxy can be updated by running this command in a Terminal window: Step #2: Decide what type of message you want to add and how it will fit in with the existing MAVLink messages. For example, you might want to send a new navigation command to the vehicle so that it can perform a trick (like a flip) in the middle of a mission (i.e. in AUTO mode).
Is there a backwards compatible version of MAVLink?
MAVLink2 is backwards compatible with MAVLink1 meaning that if a device understands MAVlink2 messages it certainly understands MAVLink1 messages If a device only capable of understanding MAVLink1 receives a message that includes additional fields (added under MAVLink2) the device will only see the original fields.
