I am using TemperatureSensor iOS sample app which didDiscoverPeripheral did not called. By reference the flow of Heart Rate Monitor Mac sample app. Please make sure the run sequence of code is:

1. centralManager = [[CBCentralManager alloc] initWithDelegate:self queue:dispatch_get_main_queue()];
2. - (void) centralManagerDidUpdateState:(CBCentralManager *)central
3. [centralManager scanForPeripheralsWithServices:... 

- (void) centralManager:(CBCentralManager *)central didDiscoverPeripheral:... will be called afterwards.
