I do have another BLE issue which is difficult to reproduce and wondered if anyone else had seen it and/or had experience working around it. On every normal initial connect (without security keys exchanged yet) we follow this procedure: * Discover services * Set notify enable on a particular characteristic (Pairing dialog appears) * Receive -peripheral:didUpdateNotificationStateForCharacteristic:error: after pairing is complete If I have paired my device with the iPhone, then subsequently removed the security keys on both sides (iPhone - Forget this Device), then attempt to connect again, I sometimes see -peripheral:didUpdateNotificationStateForCharacteristic:error: return with CBErrorDomain code=0 This return happens immediately, then the Pairing dialog appears. Pairing appears to succeed, but there are no further callbacks. Once this has happened once, it happens on every connect to that peripheral. Turning Bluetooth off/on in Settings is sufficient to reset to the expected behaviour. I've seen this on iOS 6.1.2 and iOS 6.1.3.
