Question

我正在开发一款应用程序，我必须从Mio-Fuse等BLE设备中获取燃烧卡路里。

我可以从Apple Watch的Health工具包中获取数据，但是当涉及到BLE可穿戴任何API时，我无法追踪服务ID或特征ID。所以请帮助我。

提前致谢

您需要发布代码才能获得帮助。首先查找您的设备 - 代码是obj c但您应该可以轻松地相应地更改swift

  if (central.state == CBCentralManagerStatePoweredOn) {
    [_centralManager scanForPeripheralsWithServices:@[[CBUUID UUIDWithString:@"0x180A"]] options:@{CBCentralManagerScanOptionAllowDuplicatesKey : @YES}];
    NSLog(@"Start scanning");
}

如果成功，那么寻找像这样的特征

 - (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI {

for (CBService *service in peripheral.services) {
    NSLog(@"Discovered service1: %@", service.UUID);
    [peripheral discoverCharacteristics:nil forService:service];
}
if (_discoveredPeripheral != peripheral) {
    // Save a local copy of the peripheral, so CoreBluetooth doesn't get rid of it
    _discoveredPeripheral = peripheral;

    // And connect
    NSLog(@"Connecting to peripheral %@", peripheral);
    [_centralManager connectPeripheral:peripheral options:nil];
}
}

一旦连接，您将获得特征
