Way over-engineered. What most people don’t realize is that Bluetooth isn’t just a PHY layer, or a data decription or ‘just’ an anything - it’s everything. Who would make a spec to be 6 layers of an OSI model (only a slight exageration). USB doesn’t really care what you send over it after a few base class types, BT does. BT Classic is really bad in the type of designed by committee way. BT Low Energy is alright imo, but intentionally limited (no SPP, 16bit SIG approved GATTS, a 5.0 feature doesn’t “need” to fully support 5.0 in order to be called a BTLE5 device). I think the BY SIG is too big to get out of its own way.
