I’m afraid what you are trying to do will not work. I have tried to achieve the same thing. The problem is the difference in scanning in foreground and background. When you are scanning for devices in the foreground you can scan for anything. In the background you must specify the actual service UUID you … Read more
iOS 7 has a new options parameter in the create of CBCentralManager to turn this off, named CBCentralManagerOptionShowPowerAlertKey I’d love a solution for earlier iOS.
Long story short, YES you can use the UUID to reconnect to the same device even after you close the application (in exactly the way you say). I assume however, that you are not actually pairing with peripheral. That’s a big problem right there. You need to actually establish the pairing request and get the … Read more
Check if your methods are implemented in the following way. In viewDidLoad, start moniotoring at the end self.beaconRegion.notifyOnEntry=YES; self.beaconRegion.notifyOnExit=YES; self.beaconRegion.notifyEntryStateOnDisplay=YES; [self.locationManager startMonitoringForRegion:self.beaconRegion]; after monitoring start, request state for your defined region – (void) locationManager:(CLLocationManager *)manager didStartMonitoringForRegion:(CLRegion *)region { [self.locationManager requestStateForRegion:self.beaconRegion]; } after state is determined, start ranging beacons -(void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region { if … Read more
The experience of Matthew Griffin matches mine. However – when we can measure for a fair period of time two things have helped us calibrate this better. We did have to wrap a simple (kalman) filter on the antenna orientation and the IMU to get a rough running commentary though – and this is not … Read more
I’ve already gone through this for at least one week having this same issue. I’ve already asked a question here and I’ve already answered on my own. The main problem is an Android BUG issue. It’s sending a non permitted command on a fixed L2CAP channnel. But when Android is communicating with normal peripheral BLE … Read more
First you will need to configure your applications audio session to allow bluetooth connections that support audio. You can do this in, for example, your application delegates – (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method. Make sure you link the AVFoundation Framework and import in headers that will use it. #import <AVFoundation/AVFoundation.h>// place in .h [self prepareAudioSession];// … Read more
Create a Singleton class and add bleManager and peripheral properties there: class Shared { private init(){ } static let instance = Shared() var bleManager: BLEManager! var peripheral: CBPeripheral! } And you can access the same instance through different controllers: Shared.instance.bleManager = BLEManager()
Nobody seemed to know, so I bought an iOS developer account and ran some experiments. Here’s what I found: When running in the foreground, you can start a scan using CBCentralManager::scanForPeripheralsWithServices. Your scan can be restricted to devices advertising a particular service, or unrestricted (pass nil for that call’s parameter). It can also allow or … Read more
Yes, it’s possible and should be automatic. After you have created a CLBeaconRegion and started monitoring on it, Location Services will keep track of whether your phone is in or out of the region, even when your app isn’t running. If you app isn’t running during a transition, iOS will launch your app into the … Read more
