Long, first concern I have is that you don't seem to stop scanning prior to connecting. This can lead to very long connect times. Regarding your warnings: 1. the didDisconnectPeripheral message makes sense and describes in the error parameter that you took your power off. 2. the warnings that are spammed seem to occur when you try to access a device that is not connected anymore. To find out where this occurs, you should log every call to your CBPeripheral. As soon as the didDisconnectPeripheral message arrives, you should refrain from accessing your CBPeripheral again. 3. In order to reconnect, it is necessary to issue another connect request. Reconnection does not happen automatically. Hoping that this can help you.

Connect issue, didDisconnect(Time out) and CoreBluetooth[WARNING]
by Long LI 05 Dec '12

05 Dec '12

Hi I am testing Connect and Reconnect issue, using iPhone5 ios6.0.1 and TI CC2540 BLE Kit. I need some help. Here is my program sequences: scan - didDiscover - connect - didConnect - discoverServices - POWER OFF - didDisconnect(Time out) - CoreBluetooth[WARNING] (many times) - POWER ON - didDiscover - CoreBluetooth[WARNING] (many times) When I power off BLE Kit, a timeout error raised, then power on, the peripheral was discovered, but I can't connect it again. the CoreBluetooth[WARNING] show many times in log. I can't catch this exception. Any Suggest? The Log: [LeDiscovery centralManager:didDisconnectPeripheral:error:] [Line 316] Error Domain=CBErrorDomain Code=6 "The connection has timed out unexpectedly." UserInfo=0x1ed7f2b0 {NSLocalizedDescription=The connection has timed out unexpectedly.} CoreBluetooth[WARNING] <CBConcretePeripheral: 0x1f891ec0 UUID = <CFUUID 0x1f892000> F99A1955-E2C2-A81F-6727-CF247135A263, Name = "", IsConnected = NO> is not connected Best Regards.

Kim, Regarding pairing rules on BLE: Normally, pairing is initiated as soon as you try to access a characteristic that requires bonding (and thus, returns an error that indicates insufficient security levels). iPhone 4S and iPod touch 5 should react similar here.
