As we're pressing the IMUs into real world applications, we're finding ourselves having to do stuff in our already overtaxed CPUs that the BNO086 supports, but for which functionality isn't exposed through depthai-core. Note that some of these are things that people have requested in the past, so maybe just consider these to be upvotes to those already-raised asks 😉
The ability to use the tare function.
The ability to write FRS records.
The ability to issue interactive calibration, and to manually persist DCD.
Getting the calibration accuracy bits back would be useful, but it's less important.
I'd be totally okay with just a generic interface to issue commands to the BNO086 consistent with the BNO08X docs 🙂
