Entering slate metadata via Bluetooth

Hi, I'm new to the BM dev scene and am in the planning stages of writing a Flutter phone app to control BM cameras via bluetooth. I've found all the control protocol info I need to get started other than how to edit slate metadata, i.e. reel, scene, shot type etc. The official BM iPad app (and some 3rd party phone apps) can do this, but I cannot find the Bluetooth protocol commands for slate editing anywhere. Can someone please advise me if this information is publicly available and, if so, point me in the right direction please? Thank you.

Answering myself for future searchers: the Bluetooth slate commands do exist and are useable, but are undocumented at this time. You can dig the details out of the downloadable code samples in the file Libraries\BluetoothControl\Common\Apple\CCU\CCUPacketTypes.swift and accompanying files.
