iOS 6 peripheral disconnect immediately after connected - ios6

Question

OK, I'm using Core Bluetooth to connect my i-Pad to another BLE sensor.
I scan and detect it easily but when I want to establish a connection, the "did connect peripheral" method is only called during 30 sec as if I've called a disconnection...
And this result stay the same even I select or deselect "App Communicates using CoreBluetooth" in Required background mode.

}
}

}
Here is my console. I don't have any warning, any error or deallocating just:
2013-05-14 09:21:14.925 PRESSURE[262:907] connected
2013-05-14 09:21:14.927 PRESSURE[262:907] Service (Sensor) connected
2013-05-14 09:21:44.994 PRESSURE[262:907] Service (Sensor) disconnected
How can I avoid my peripheral disconnected immediately after connection please?
It drives me crazy!

Answer 1

You have to do [peripheral retain] on didDiscoverPeripheral or put it into the retain property.
It is released right after the connect by BLE framework.
