When I was getting this message, I checked console messages in the Organizer.

Doesn't seem useful unless you know how this tiny device exactly works. I wasted a couple hours to play with entitlements and other stuff that might be related to this issue. There was no luck. Then I finally figured out what I did wrong. You probably made a same mistake just like I did.

Didn't you put the whole App ID that you copied from the iPhone developer portal? Don't do this!

Put

com.domainname.appname

Instead of

XXXXXXXX.com.domainname.appname

I should've read the manual more carefully ;-)

BOOM!

If this is not your case, well, you might want look for other solutions. Good luck.
