iOS6: CBPeripheral is being dealloc'ed while connecting
Short answer: You need to retain the peripheral.
Long explanation: Core Bluetooth does not know whether you are interested in this peripheral when it is discovered. Connecting to it is not enough, you need to retain it.
Add a property to the class where you are doing all that:
@property (strong) CBPeripheral *connectingPeripheral;And then assign the peripheral to this property when the device is discovered, before you return from didDiscoverPeripheral:
- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI{ DDLogVerbose(@"Discovered peripheral: %@ advertisement %@ RSSI: %@", [peripheral description], [advertisementData description], [RSSI description]); [central connectPeripheral:peripheral options:nil]; self.connectingPeripheral = peripheral;}
