I initialize the CBCenteralManager in viewdidload on main queue. First time update state method is called and start scanning for bluetooth devices but didDiscoverPeripheral: delegate method never get called.
Code is :
- (void)viewDidLoad
{
[super viewDidLoad];
self.CM = [[CBCentralManager alloc]initWithDelegate:self queue:nil];
}
-(void)centralManagerDidUpdateState:(CBCentralManager *)central{
if (central.state == CBCentralManagerStatePoweredOn) {
[self.CM scanForPeripheralsWithServices:nil options:nil];
}
}
- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral(CBPeripheral*)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI {
}
-(void)centralManager:(CBCentralManager *)central didRetrievePeripherals:(NSArray *)peripherals{
}
-(void)centralManager:(CBCentralManager *)central didRetrieveConnectedPeripherals:(NSArray *)peripherals{
}
-(void)centralManager:(CBCentralManager *)central didFailToConnectPeripheral:(CBPeripheral *)peripheral error:(NSError *)error{
}
-(void)centralManager:(CBCentralManager *)central didDisconnectPeripheral:(CBPeripheral *)peripheral error:(NSError *)error{
}
-(void)centralManager:(CBCentralManager *)central didConnectPeripheral:(CBPeripheral *)peripheral{
}
