I am trying CBPeripheralManager on iPad and CBCentralManager on iPhone 4S and I can't make service discovery work. This is what I do: In peripheralManagerDidUpdateState when state changes to CBPeripheralManagerStatePoweredOn I add services and start advertising: CBUUID *cUDID = [CBUUID UUIDWithString:@"DA18"]; CBUUID *cUDID1 = [CBUUID UUIDWithString:@"DA17"]; CBUUID *cUDID2 = [CBUUID UUIDWithString:@"DA16"]; CBUUID *sUDID = [CBUUID UUIDWithString:@"DA00"]; characteristic = [[CBMutableCharacteristic alloc]initWithType:cUDID properties:CBCharacteristicPropertyNotify value:nil permissions:CBAttributePermissionsReadable]; characteristic1 = [[CBMutableCharacteristic alloc]initWithType:cUDID1 properties:CBCharacteristicPropertyWrite value:nil permissions:CBAttributePermissionsWriteable]; characteristic2 = [[CBMutableCharacteristic alloc]initWithType:cUDID2 properties:CBCharacteristicPropertyRead value:nil permissions:CBAttributePermissionsReadable]; servicea = [[CBMutableService alloc] initWithType:sUDID primary:YES]; servicea.characteristics = @[characteristic,characteristic1,characteristic2]; [peripheral addService:servicea]; NSDictionary *advertisingData = @{CBAdvertisementDataLocalNameKey : @"peri"}; [self.peripheralManager startAdvertising:advertisingData]; On central device when the device is discovered it establishes connection and when that is done discovers services and service characteristics, but all I can find is Generic Access (0x1800) service with device name characteristics. I tried to run demo applications from other people github where it makes a device advertise with custom services, but I still find the same 0x1800 service only. iPad is running iOS v6.1. Anyone has a clue what is going on? _______________________________________________ Do not post admin requests to the list. They will be ignored.
