I’m trying to get the GKTank example working with 2 iPhones. Both have bluetooth enabled. I start the app on both devices and tap the screen. The Peer Picker comes up and the devices find each other. If I select one device in the list it says "Waiting for {other iPhone}…" forever. On the {other iPhone} the waiting phone gets grayed out. If I select the device to connect to from both devices at the same time both go into waiting state forever…
The debug log says this if I select the other iPhone on the debugged device:

and it stays that way. On the second iPhone the device is listed as not available and grayed out.
If I select each other at the same time it says this:

… and waits forever.
Does anybody know whats wrong with this sample??
Nevermind, turning bluetooth off and on again fixed the issiue 😛 I love to be dependant on that kind of reliability…
