MAVLink Microservices (Protocols)

MAVLink "microservices" are a protocols that use multiple messages exchanged between components to communicate more complicated information. For example, the Command Protocol provides an efficient mechanism for packaging a command in a (particular) message and receiving acknowledgement of the command in another message.

MAVLink microservices are documented the MAVLink Guide (this is not exhaustive: not all messages are grouped into protocols and not all protocols are documented).

This section lists the services known to be supported/not supported by PX4 in this version.
