I have an app that can browse for Bonjour published services and join to Bonjour services in order to exchange data. It has been working well, using Bluetooth, until it stopped working in iOS 10. It still works fine using WiFi but, in BT, it only sees the published services but they can not exchange data. We are also obtaining the same behavior with a different app that uses DNS-SD API to make the communication channel.
You can confirm this behaviour trying Chatty (code found in Github) but taking into account to set the includesPeerToPeer property on both sides (as mentioned in Technical Q&A QA1753)
If you download the BT Chat HD app from the App Store, it is the same. It works for iOS9 but not for iOS 10.0.2.
Is someone else experiencing the same?
