iOS CoreBluetooth / iBeacon: Advertise an iBeacon and a peripheral service concurrently

Question

I\'m writing an application for iOS that requires that the application advertise both an iOS iBeacon as well as advertise peripheral service concurrently. It\'s necessary th

Answer 1

I was able to get this going with a separate CLLocationManager and CLBeaconRegion for both the reciever and the beacon separately:

#import "GRBothViewController.h"

@interface GRBothViewController ()

@end

@implementation GRBothViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];


    self.locationManager = [[CLLocationManager alloc] init];
    self.locationManager.delegate = self;

    self.locationScanner = [[CLLocationManager alloc] init];
    self.locationScanner.delegate = self;

    [self initBeacon];
    [self initRegion];
    [self locationManager:self.locationManager didStartMonitoringForRegion:self.scannerRegion];
}

- (void)initBeacon {
    NSLog(@"Starting beacon");

    NSUUID *uuid = [[NSUUID alloc] initWithUUIDString: @"23542266-18D1-4FE4-B4A1-23F8195B9D39"];
    self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uuid
                                                                major:1
                                                                minor:1
                                                           identifier:@"com.thisisgrow.Grow"];
    [self transmitBeacon:self];
}

- (IBAction)transmitBeacon:(id)sender {
    self.beaconPeripheralData = [self.beaconRegion peripheralDataWithMeasuredPower:nil];
    self.peripheralManager = [[CBPeripheralManager alloc] initWithDelegate:self
                                                                     queue:nil
                                                                   options:nil];
}

-(void)peripheralManagerDidUpdateState:(CBPeripheralManager *)peripheral {
    if (peripheral.state == CBPeripheralManagerStatePoweredOn) {
        NSLog(@"Powered On");
        [self.peripheralManager startAdvertising:self.beaconPeripheralData];
    } else if (peripheral.state == CBPeripheralManagerStatePoweredOff) {
        NSLog(@"Powered Off");
        [self.peripheralManager stopAdvertising];
    }
}

- (void)locationManager:(CLLocationManager *)manager didStartMonitoringForRegion:(CLRegion *)region {
    [self.locationManager startRangingBeaconsInRegion:self.beaconRegion];
}

- (void)initRegion {
    NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:@"23542266-18D1-4FE4-B4A1-23F8195B9D39"];
    _scannerRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uuid identifier:@"com.thisisgrow.Grow"];
    _scannerRegion.notifyEntryStateOnDisplay = YES;
    [_locationScanner startMonitoringForRegion:self.scannerRegion];
}

- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region {
    //SCANNER
    [self.locationScanner startRangingBeaconsInRegion:self.scannerRegion];
}

-(void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region {
    //SCANNER HAS LEFT THE AREA
    [self.locationScanner stopRangingBeaconsInRegion:self.scannerRegion];
}

-(void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region {
    CLBeacon *beacon = [[CLBeacon alloc] init];
    NSLog(@"Beacons: %d", [beacons count]);
    if(beacons && [beacons count]>0){
        beacon = [beacons firstObject];
    }
    else{

    }
}

The only limitation here is that the device cannot detect itself.

Answer 2

In my practice, iBeacon & BLE service can not advertise at same time.

BLE service can not advertise in foreground if advertise mixed with iBeacon. iBeacon can not advertise in background.

iBeacon & BLE service can advertise one by one, e.g. iBeacon advertise 0.5 seconds, then BLE service advertise 30.0 seconds.

Hope this will helpful
