ios6 - iOS 6 peripheral disconnect immediately after connected -


ok, i'm using core bluetooth connect i-pad ble sensor. scan , detect when want establish connection, "did connect peripheral" method called during 30 sec if i've called disconnection... , result stay same select or deselect "app communicates using corebluetooth" in required background mode.

here console. don't have warning, 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 avoid peripheral disconnected after connection please? drives me crazy!

you have [peripheral retain] on diddiscoverperipheral or put retain property. released right after connect ble framework.
