So apparently they use Bluetooth to establish the connection and WiFi for the data transfer. This sounds a lot like the "Alternative MAC/PHY" feature which was added in Bluetooth 3.0 and then removed in Bluetooth 5.3 [1] due to low uptake.

Why didn't the standard Bluetooth way of doing this gain any traction? What was wrong with it?
