我正在开发一个用于心率监测的 iOS 应用程序，并希望使用蓝牙将 garmin 设备连接到我的应用程序。
但我无法使用（180D 服务 UUID）在 Swift 中使用 Core bluetooth 列出任何 Garmin 设备。
func startUpCentralManager() {
print("Initializing central manager")
centralManager = CBCentralManager(delegate: self, queue: nil)
}
func discoverDevices() {
print("discovering devices")
let services = [CBUUID(string: HRM_HEART_RATE_SERVICE_UUID),CBUUID(string:HRM_DEVICE_INFO_SERVICE_UUID),CBUUID(string:HRM_DEVICE_BATTERY_LEVEL_SERVICE_UUID),CBUUID(string:CALORIE_SERVICE)]
centralManager.scanForPeripherals(withServices: services, options: nil)
}
//MARK: CBCentralManagerDelegate
func centralManagerDidUpdateState(_ central: CBCentralManager) {
print("checking state")
switch (central.state) {
case .poweredOff:
print("CoreBluetooth BLE hardware is powered off")
case .poweredOn:
print("CoreBluetooth BLE hardware is powered on and ready")
blueToothReady = true;
case .resetting:
print("CoreBluetooth BLE hardware is resetting")
case .unauthorized:
print("CoreBluetooth BLE state is unauthorized")
case .unknown:
print("CoreBluetooth BLE state is unknown");
case .unsupported:
print("CoreBluetooth BLE hardware is unsupported on this platform");
}
if blueToothReady {
discoverDevices()
}
}
func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
let nameOfDeviceFound = (advertisementData as NSDictionary).object(forKey: CBAdvertisementDataLocalNameKey) as? NSString
print("\(String(describing: nameOfDeviceFound))")
print("Discovered Peripheral name : ", peripheral.name ?? String())
if !Utilities.allPeripheralList.contains(peripheral)
{
Utilities.allPeripheralList.add(peripheral)
}
let deviceObj = DeviceModel()
deviceObj.deviceName = peripheral.name ?? String()
deviceObj.UDID = String(format: "%@",(peripheral.identifier).uuidString)
self.addingPeripheralToGlobalSearchArray(obj: deviceObj)
}
func centralManager(_ central: CBCentralManager, didConnect peripheral: CBPeripheral) {
peripheral.delegate = self
peripheral.discoverServices(nil)
self.connected = peripheral.state == CBPeripheralState.connected ? "YES" : "NO"
print("Connection Status : %@", self.connected)
if self.connected == "YES"{
Utilities.sharedInstance.goToDashboardTabBarScreen(viewController: self)
}
}
func centralManager(_ central: CBCentralManager, didDisconnectPeripheral peripheral: CBPeripheral, error: Error?) {
// central.scanForPeripherals(withServices: nil, options: nil)
}
func addingPeripheralToGlobalSearchArray(obj:DeviceModel){
var isFound:Bool = false
for i in 0..<Utilities.allDeviceList.count{
let deviceObj = Utilities.allDeviceList[i] as! DeviceModel
if obj.UDID == deviceObj.UDID{
isFound = true
}
}
if !isFound{
Utilities.allDeviceList.add(obj)
}
}
以上是我用来列出 BLE 设备的代码。我能够找到使用相同代码和平的 Mio-Fuse 设备，但不是 Garmin 设备。
