Question

I want use CoreBluetooth.framework in IOS8 to achieve data transfer, i did discover peripheral in the follow method and try connect the peripheral.

- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI
{
    NSLog(@"Discover name : %@", peripheral.name);
    [self.centralManager connectPeripheral:peripheral options:nil];
}

But it did not call the delegate methods didFailToConnectPeripheral or didConnectPeripheral , I waner what's wrong with it, is the code error or IOS8 need some extra things ? How to deal it, thank in advance!

@Sj comment solved it for me, copying it into an answer in case someone will miss it:

Did u tried storing the peripheral object in an ivar and then connect to it? ie self.discoveredPeripheral = peripheral; [self.centralManager connectPeripheral:self.discoveredPeripheral options:nil];
