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 Unit [Frame] 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)
