MavlinkTunnel (UORB message)

MAV_TUNNEL_PAYLOAD_TYPE enum.

TOPICS: mavlink_tunnel esc_serial_passthru io_serial_passthru

Fields

Name	Type	Unit [Frame]	Range/Enum	Description
timestamp	uint64			Time since system start (microseconds)
payload_type	uint16			A code that identifies the content of the payload (0 for unknown, which is the default). If this code is less than 32768, it is a 'registered' payload type and the corresponding code should be added to the MAV_TUNNEL_PAYLOAD_TYPE enum. Software creators can register blocks of types as needed. Codes greater than 32767 are considered local experiments and should not be checked in to any widely distributed codebase.
target_system	uint8			System ID (can be 0 for broadcast, but this is discouraged)
target_component	uint8			Component ID (can be 0 for broadcast, but this is discouraged)
payload_length	uint8			Length of the data transported in payload
payload	uint8[128]			Data itself

Constants
