iPhone 5s cannot perform Bluetooth Tethering under iOS 8
Hi all.
I've upgraded my iPhone 5S (Model A1530) from iOS 7.1.2 to iOS 8.0 last night.
Today when I went back to headquarters of my company (which is using an access point that reject my mid-2010 13" MacBook Pro's (Model A1278, OS X Mavericks 10.9.5) Wi-Fi under OS X) I had to turn on the hotspot function to get access to the Internet.
Strange things happened when I tried to build a tethering between my iPhone 5S and my Mac, no tethering was built after clicking "Connect to network" in Bluetooth menu. I tried to remove the device from both my iPhone and Mac and try to re-pair them, they did pair and connect, but the Mac cannot get a valid IP address from the phone and cannot connect again once disconnected, the Bluetooth icon in my phone just blink a few times then return to unconnected state.
I tried to reset all the network settings but without any success.
Before upgrading to iOS 8.0 my phone was able to create Bluetooth Tethering with the phone. Also, I have an spare iPhone 3Gs (Model A1303) running iOS 6.1.2 and I've just tested Bluetooth tethering with it, the Mac just connected smoothly. So base on all these evidence, the root cause of the problem is most likely the iOS 8 on my iPhone 5S. Does a wipe and restore help?
Thanks.
iPhone 5s, iOS 8
