MAVLink Minimal Set (minimal.xml)

The MAVLink minimal set contains the minimal set of definitions for a viable MAVLink system.

The message set is defined in minimal.xml and is managed by the MAVLink project.

TIP

The minimal set is included (imported into) other xml definition files, including the MAVLink Common Message Set (common.xml).

Messages

HEARTBEAT (0)

The heartbeat message shows that a system or component is present and responding. The type and autopilot fields (along with the message component id), allow the receiving system to treat further messages from this system appropriately (e.g. by laying out the user interface based on the autopilot). This microservice is documented at https://mavlink.io/en/services/heartbeat.html

Field Name	Type	Values	Description
type	uint8_t	MAV_TYPE	Vehicle or component type. For a flight controller component the vehicle type (quadrotor, helicopter, etc.). For other components the component type (e.g. camera, gimbal, etc.). This should be used in preference to component id for identifying the component type.
autopilot	uint8_t	MAV_AUTOPILOT	Autopilot type / class. Use MAV_AUTOPILOT_INVALID for components that are not flight controllers.
base_mode	uint8_t	MAV_MODE_FLAG	System mode bitmap.
custom_mode	uint32_t		A bitfield for use for autopilot-specific flags
system_status	uint8_t	MAV_STATE	System status flag.
mavlink_version	uint8_t_mavlink_version		MAVLink version, not writable by user, gets added by protocol because of magic data type: uint8_t_mavlink_version

PROTOCOL_VERSION (300) — [WIP]

WORK IN PROGRESS: Do not use in stable production environments (it may change).

Version and capability of protocol version. This message can be requested with MAV_CMD_REQUEST_MESSAGE and is used as part of the handshaking to establish which MAVLink version should be used on the network. Every node should respond to a request for PROTOCOL_VERSION to enable the handshaking. Library implementers should consider adding this into the default decoding state machine to allow the protocol core to respond directly.

Field Name	Type	Description
version	uint16_t	Currently active MAVLink version number * 100: v1.0 is 100, v2.0 is 200, etc.
min_version	uint16_t	Minimum MAVLink version supported
max_version	uint16_t	Maximum MAVLink version supported (set to the same value as version by default)
spec_version_hash	uint8_t[8]	The first 8 bytes (not characters printed in hex!) of the git hash.
library_version_hash	uint8_t[8]	The first 8 bytes (not characters printed in hex!) of the git hash.

MAV_COMPONENT

Component ids (values) for the different types and instances of onboard hardware/software that might make up a MAVLink system (autopilot, cameras, servos, GPS systems, avoidance systems etc.).

Components must use the appropriate ID in their source address when sending messages. Components can also use IDs to determine if they are the intended recipient of an incoming message. The MAV_COMP_ID_ALL value is used to indicate messages that must be processed by all components. When creating new entries, components that can have multiple instances (e.g. cameras, servos etc.) should be allocated sequential values. An appropriate number of values should be left free after these components to allow the number of instances to be expanded.

Value	Name	Description

236	MAV_COMP_ID_ODID_TXRX_1	Open Drone ID transmitter/receiver (Bluetooth/WiFi/Internet).
237	MAV_COMP_ID_ODID_TXRX_2	Open Drone ID transmitter/receiver (Bluetooth/WiFi/Internet).
238	MAV_COMP_ID_ODID_TXRX_3	Open Drone ID transmitter/receiver (Bluetooth/WiFi/Internet).
240	MAV_COMP_ID_UDP_BRIDGE	Component to bridge MAVLink to UDP (i.e. from a UART).
241	MAV_COMP_ID_UART_BRIDGE	Component to bridge to UART (i.e. from UDP).
242	MAV_COMP_ID_TUNNEL_NODE	Component handling TUNNEL messages (e.g. vendor specific GUI of a component).
243	MAV_COMP_ID_ILLUMINATOR	Illuminator
250	MAV_COMP_ID_SYSTEM_CONTROL	Deprecated, don't use. Component for handling system messages (e.g. to ARM, takeoff, etc.). DEPRECATED: Replaced By MAV_COMP_ID_ALL (2018-11) — System control does not require a separate component ID. Instead, system commands should be sent with target_component=MAV_COMP_ID_ALL allowing the target component to use any appropriate component id.)
