Since the Multipeer Connectivity framework no longer supports Bluetooth. (https://developer.apple.com/forums/thread/749346)
Why does its official documentation still mention "In iOS, the framework uses infrastructure Wi-Fi networks, peer-to-peer Wi-Fi, and Bluetooth personal area networks for the underlying transport." ?(https://developer.apple.com/documentation/multipeerconnectivity)
What is the purpose of using Bluetooth personal area networks for the underlying transport?
Why Does the Multipeer Connectivity Framework Documentation Mention Bluetooth if It's No Longer Supported?
Because it’s not been update to reflect this change in policy. Please do file a bug against the documentation about this [1].
Keep in mind that Multipeer Connectivity is effectively deprecated. While we haven’t officially deprecated it [2], most use cases are better served by other networking APIs. See TN3151 Choosing the right networking API for more on that.
If you plan to use Multipeer Connectivity for new code, I recommend that you think carefully before doing that. If you’d like specific advice, please post details about your high-level goal and I’ll explain the best path forward.
