[英]Detecting Apple Watch Using CoreBluetooth
我在 iPhone 上发现了使用 Core Bluetooth 的蓝牙设备,但它无法连接 Apple Watch。 有什么我想念的吗? 这是我在下面使用的代码:
#pragma mark - CBCentralManagerDelegate
// method called whenever you have successfully connected to the BLE peripheral
- (void)centralManager:(CBCentralManager *)central didConnectPeripheral:(CBPeripheral *)peripheral
{
}
// CBCentralManagerDelegate - This is called with the CBPeripheral class as its main input parameter. This contains most of the information there is to know about a BLE peripheral.
- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI
{ NSLog(@"%@", [peripheral name]);
}
// method called whenever the device state changes.
- (void)centralManagerDidUpdateState:(CBCentralManager *)central
{
switch ([central state])
{
case CBCentralManagerStatePoweredOff:
NSLog(@"CoreBluetooth BLE hardware is powered off");
break;
case CBCentralManagerStatePoweredOn:
NSLog(@"CoreBluetooth BLE hardware is powered on and ready");
[[self bluetoothManager] scanForPeripheralsWithServices:nil options:nil];
break;
case CBCentralManagerStateResetting:
NSLog(@"CoreBluetooth BLE hardware is resetting");
break;
case CBCentralManagerStateUnauthorized:
NSLog(@"CoreBluetooth BLE state is unauthorized");
break;
case CBCentralManagerStateUnknown:
NSLog(@"CoreBluetooth BLE state is unknown");
break;
case CBCentralManagerStateUnsupported:
NSLog(@"CoreBluetooth BLE hardware is unsupported on this platform");
break;
default:
break;
}
}
当我运行以下代码时,我的 Apple Watch 就会出现:
[self.centralManager retrieveConnectedPeripheralsWithServices:@[[CBUUID UUIDWithString:@"180A"]]];
180A
是设备信息服务。
不确定您可以发现和订阅哪些特征(如果有),但您绝对可以检测到手表的存在。
你不使用 Core Bluetooth 连接到 Apple Watch 你使用另一个称为连接的框架
