I've never worked on the BT stack, and I have only very high-level idea of how it works. But no matter the hardware, the operating system and the use case, BT is orders of magnitude less reliable than WiFi and other wireless protocols, and I don't understand why.
Some things that are surprising:
1. Devices from the same manufacturer can't see each other
2. Bluetooth audio turns choppy for no reason
3. I have never seen BT work at all on Windows, even in 2024. I cannot think of a single example where I managed to connect a BT device to a Windows computer.
4. BT audio is sensitive to my body moving, for example bluetooth headphones consistently drop audio when I walk at a specific pace.
Is the main source of problems something about the range of frequencies BT uses? Is it a hardware problem, maybe due to the low power? Why haven't we been able to make it work reliably even after 25 years?
