问题
I have developed an application that communicates with nearby devices using multipeer connectivity framework in Swift 3 iOS10 SDK. It works as expected in iPads using only Bluetooth but it doesn't work in iPhones if wifi is set to off, and I want to use only Bluetooth. If it is the issue with IPv6 then how to enable it. Thanks,

The current consensus is this is a bug in iOS 10 (we're in the same boat, it just stopped working.)
