Just like Bluetooth. As a user, you don't care whether it's the protocol or the implementation, you just cross fingers and hope it works.

I actually haven't had any problems with Bluetooth in a long while. It mostly just works at this point.

I can reliably reproduce pairing issues between fairly modern devices (e.g. both bought in 2020).
