I am seeing a very strange issue and I am hoping someone can help.
The very first time an iPhone sees a Peripheral, the UUID is returned as "null".
This has been discussed before (it is a new feature of iOS6) and is not directly the problem, because supposedly you should be able to connect anyway and all subsequent connections you make will show a valid UUID.
However, during this initial connection, I find that the iPhone decides to disconnect the connection immediately after the connection has been established. When I see an "unwanted" disconnect I immediately try to reconnect again from within the "didDisconnect" method. The result is that I end up with a never ending sequence of connect, disconnect, connect, disconnect....
The only way to fix this is to I to exit the app, re-power the peripheral, and restart the app. From now on and forever after this particular iPhone+Peripheral connection works wonderfully.
So to summarize, it is the very first connection that is giving this headache.
Has anyone else seen this, and what is correct way to address this issue?

Application communicates with a bluetooth accessory while running in
the background. I am wondering is there a limit how much the
peripheral can interrupt the phone? Can the application be rejected if
peripheral gives too much load for the phone reducing battery life?
