Hi, I'm writing an app for iOS 5.1, which would connect to discovered BTLE devices and read some data off them (BTLE devices advertise proprietary Bluetooth service). Currently it works in the foreground mode, but I want to make it work in the background mode. This should be possible with CoreBluetooth. Based on Apple documentation, I've added UIBackgroundModes key with the "bluetooth-central" value in its Info.plist, but it doesn't seem to be working. Whenever I turn off the iPhone's screen or just put application into the background, it just stops receiving CoreBluetooth discovery (centralManager:didDiscoverPeripheral:advertisementData:RSSI: callback) notifications and I can't discover/connect to BTLE devices around. Do you have a guess what could be the problem? As I mentioned before in foreground mode application works just fine. Thanks for the help, Murad _______________________________________________ Do not post admin requests to the list. They will be ignored.
