Figure 1-31: FRS records
FRS records are written by use of FRS read and write requests. Writing and reading FRS records follows a multi-
step protocol.
For writes an FRS Write Request is issued indicating which FRS record to write and the amount of data to be
written. The BNO080 will respond with a write response acknowledging the request. The host will then issue a
number of FRS Write Data packets to which the BNO080 will respond. The final response from the BNO080 will
indicate a successful conclusion to the flash writes or if the process failed a failure indication.
An FRS read follows a similar pattern. An FRS Read request is issued and FRS Read responses provide the data
with the final response indicating completion of the record retrieval.
1.4.4 Sensor Metadata
The BNO080 operates as a sensor hub and as such provides processing of sensor data. In order for a user to
understand the capabilities of the sensors, metadata is provided that describes those capabilities. The SH-2
reference manual provides full details of the metadata record but as an example Figure 1-32 provides the
metadata for the rotation vector. Metadata is stored as an FRS record and is therefore retrieved as an FRS read.

Version
Identifies the physical sensor/driver/fusion versions for a given sensor.
The elements within this field are updated when a component changes
in a manner that affects the output of the sensor.
