Changes to Bluetooth Camera Control API on Pocket 6k?

I purchased a Pocket 6k to test with my Android control app. Everything is working as expected with the exception of the Focus control.

Can you tell me if something changed in the 6k, or in the latest OS? I'd like to update the app to work correctly asap. I'm using the BlackmagicCameraControl.pdf document for all the API information. The command in question is 0.0 Lens.Focus. I'm writing a fixed16 value using a type of 0x80 (128) like I do on the 4k and it does not respond.

Any help would be much appreciated. Maybe a new API PDF is in the works? I really hope this functionality was not disabled. -Derek

Edit:
I've found when using operation 1 (add) instead of 0 (set) it's working. Hopefully this is just a bug.

No love on this BM? I need to send the absolute focus value to the camera. The only way it works right now is if I send a delta with mode 1.
