But if the spec as a whole is bad, all layers of the spec are bad, the implementations are all bad, and the user experience is bad, then in what way can Bluetooth be described as anything but bad?
> if the spec as a whole is bad, all layers of the spec are bad,
This discussion is intriguing. I wonder how many people commenting on "the spec" have actually read any part of "the spec" in question (I have).
And since we're posting anecdata: I can't think of a single problem I've had with a Bluetooth device in recent years, and I use a lot of Bluetooth devices. So this kind of generalizing doesn't help.
As a counterpoint, every embedded device that uses Wi-Fi promises a world of pain. The bizarre pairing procedures, connecting to temporary access points, entering passwords — it's all a combination of pain, timeouts, problems, and resets. But that doesn't lead me to state that "wifi is bad, the spec as a whole is bad, all layers of the spec are bad, the implementations are all bad".
Sometimes it is the hardware, sometime it is the software.
Two xiaomi phone models with different BT issues: One couldn't connect to two chipolos, the other loses wifi stability when connected to A2DP (ping raises, connection stutters and as the BT devices get closer, connection is lost randomly) Samsung phone: no issues [detected so far]
Then I have some Sennheiser headphones that I can get stuck and need to be physically turned on / off when it loses connection due to distance and there are other phones nearby (I roam around the house without the phone. I know that's partially on me)
I remember the time there was for windows a "BlueSoleil" BT stack besides the "Broadcomm" stack. Blue soleil was more stable, supported more profiles (pan, a2dp, etc) on more devices.
And, all those BT security issues over time? It makes me feel BT protocol cockroaches always come back.
Apple has no excuse since they control both hardware and software. They are dropping the ball.

They don't control the Bluetooth hardware though - that's still Broadcom AFAIK (at least in this 2021 Macbook M1 Pro and my 2023 M3 Max.) They might be writing the driver (I don't know if they are or if they're just interfacing with a Broadcom shim) but that doesn't necessarily help if the hardware is shonky balls.
