# 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](https://github.com/mavlink/mavlink/blob/master/message_definitions/v1.0/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)](minimal.md).

## Messages

### HEARTBEAT (0) {#HEARTBEAT}

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](#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](#MAV_AUTOPILOT) | Autopilot type / class. Use [MAV_AUTOPILOT_INVALID](#MAV_AUTOPILOT_INVALID) for components that are not flight controllers. 
base_mode | `uint8_t` | [MAV_MODE_FLAG](#MAV_MODE_FLAG) | System mode bitmap. 
custom_mode | `uint32_t` | | A bitfield for use for autopilot-specific flags 
system_status | `uint8_t` | [MAV_STATE](#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] {#PROTOCOL_VERSION}

<span class="warning">**WORK IN PROGRESS**: Do not use in stable production environments (it may change).</span>

Version and capability of protocol version. This message can be requested with [MAV_CMD_REQUEST_MESSAGE](#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](#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.

The flag can still be used to report the armed state. 

### MAV_MODE_FLAG_DECODE_POSITION {#MAV_MODE_FLAG_DECODE_POSITION}

(Bitmask) These values encode the bit positions of the decode position. These values can be used to read the value of a flag bit by combining the base_mode variable with AND with the flag position value. The result will be either 0 or 1, depending on if the flag is set or not.

### MAV_COMPONENT {#MAV_COMPONENT}

Legacy component ID values for particular types of hardware/software that might make up a MAVLink system (autopilot, cameras, servos, avoidance systems etc.).


Components are not required or expected to use IDs with names that correspond to their type or function, but may choose to do so.
Using an ID that matches the type may slightly reduce the chances of component id clashes, as, for historical reasons, it is less likely to be used by some other type of component.
System integration will still need to ensure that all components have unique IDs.

Component IDs are used for addressing messages to a particular component within a system.
A component can use any unique ID between 1 and 255 ([MAV_COMP_ID_ALL](#MAV_COMP_ID_ALL) value is the broadcast address, used to send to all components).

Historically component ID were also used for identifying the type of component.
New code must not use component IDs to infer the component type, but instead check the [MAV_TYPE](#MAV_TYPE) in the HEARTBEAT message!

<a id='MAV_COMP_ID_ALL'></a>0 | [MAV_COMP_ID_ALL](#MAV_COMP_ID_ALL) | Target id (target_component) used to broadcast messages to all components of the receiving system.
