Can i broadcast multiple ibeacon signals from only one bluetooth? And How

Question

I want to simulate several ibeacon signals using my ipad bluetooth, is this possible

Answer 1

You cannot start multiple transmissions at the same time, but you can simulate this by switching between two or more transmitters with a timer. iOS devices typically send 10 proposal packets per second when transferred as iBeacon. But receivers only expect packets to be received at least once per second for normal operations.

iBeacon ( , ). :

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
        // Override point for customization after application launch.
        NSLog(@"We are going to simulate advertising multiple iBeacons simultaneously!");
        CLBeaconRegion *iBeacon1 = [[CLBeaconRegion alloc] initWithProximityUUID:[[NSUUID alloc] initWithUUIDString:@"2F234454-CF6D-4A0F-ADF2-F4911BA9FFA6"]  major:15555 minor:35001 identifier:@"iBeacon1"];
        CLBeaconRegion *iBeacon2 = [[CLBeaconRegion alloc] initWithProximityUUID:[[NSUUID alloc] initWithUUIDString:@"2F234454-CF6D-4A0F-ADF2-F4911BA9FFA6"]  major:15555 minor:35002 identifier:@"iBeacon2"];

        iBeacons = [[NSMutableArray alloc] init];
        [iBeacons addObject: iBeacon1];
        [iBeacons addObject: iBeacon2];
        measuredPower = [NSNumber numberWithInt:-59];
        currentIBeaconNumber = 0;
        self.peripheralManager = [[CBPeripheralManager alloc] initWithDelegate:self queue:dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)];
        [self rotateAdvertising];
        return YES;
    }

    - (void) configureAdvertisingForIBeaconNumber: (int) iBeaconNumber {
        if(self.peripheralManager.state!=CBCentralManagerStatePoweredOn) {
            NSLog(@"Core Bluetooth is off");
            return;
        }
        [self.peripheralManager stopAdvertising];
        NSLog(@"Transmitting as iBeacon number %d", currentIBeaconNumber);
        NSDictionary *peripheralData;
        peripheralData = [[iBeacons objectAtIndex:iBeaconNumber] peripheralDataWithMeasuredPower:measuredPower];
        [self.peripheralManager startAdvertising:peripheralData];
    }

    - (void) rotateAdvertising {
        [self configureAdvertisingForIBeaconNumber:currentIBeaconNumber];
        currentIBeaconNumber = (currentIBeaconNumber + 1) % iBeacons.count;
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW,  1000* NSEC_PER_MSEC), dispatch_get_main_queue(),                ^{
            [self rotateAdvertising];
        });
    }
