DeviceInformation (UORB message)

Device information.

Can be used to uniquely associate a device_id from a sensor topic with a physical device using serial number. as well as tracking of the used firmware versions on the devices.

TOPICS: device_information

Fields

Name	Type	Range/Enum	Description
timestamp	`uint64`		time since system start (microseconds)
device_type	`uint8`	DEVICE_TYPE	Type of the device. Matches MAVLink DEVICE_TYPE enum
name	`char[80]`		Name of device e.g. DroneCAN node name
`uint32`		Unique device ID for the sensor. Does not change between power cycles. (Invalid: 0 if not available)
