Question

我有iPhone应用程序，我想连接蓝牙设备以获得葡萄糖测量。您可以从here找到该设备。

在阅读有关Core Bluetooth的Apple文档后，我开始阅读这些tutorial。此外，我从这些链接here

获取蓝牙设备的服务ID

因此，在理解了基础知识后，我开始像在教程中一样编写代码。

这些我的代码：

#define POLARH7_HRM_DEVICE_INFO_SERVICE_UUID @"180A" // for Device Information service.
#define POLARH7_HRM_HEART_RATE_SERVICE_UUID @"1808" // For Glucose service.

NSArray *services = @[[CBUUID UUIDWithString:POLARH7_HRM_HEART_RATE_SERVICE_UUID], [CBUUID UUIDWithString:POLARH7_HRM_DEVICE_INFO_SERVICE_UUID]];
CBCentralManager *centralManager = [[CBCentralManager alloc] initWithDelegate:self queue:nil];
[centralManager scanForPeripheralsWithServices:services options:nil];
self.centralManager = centralManager;

我已经实现了CBCentralManagerDelegate和CBPeripheralDelegate的代表

我收到了centralManagerDidUpdateState

的通知

- (void)centralManagerDidUpdateState:(CBCentralManager *)central
{
    // Determine the state of the peripheral
    if ([central state] == CBCentralManagerStatePoweredOff) {
        NSLog(@"CoreBluetooth BLE hardware is powered off");
    }
    else if ([central state] == CBCentralManagerStatePoweredOn) {
        NSLog(@"CoreBluetooth BLE hardware is powered on and ready");
    }
    else if ([central state] == CBCentralManagerStateUnauthorized) {
        NSLog(@"CoreBluetooth BLE state is unauthorized");
    }
    else if ([central state] == CBCentralManagerStateUnknown) {
        NSLog(@"CoreBluetooth BLE state is unknown");
    }
    else if ([central state] == CBCentralManagerStateUnsupported) {
        NSLog(@"CoreBluetooth BLE hardware is unsupported on this platform");
    }
}

我的NSLog记录：CoreBluetooth BLE hardware is powered on and ready.

但我没有收到central didDiscoverPeripheral的通知。

- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI
{
    NSString *localName = [advertisementData objectForKey:CBAdvertisementDataLocalNameKey];
    if ([localName length] > 0) {
        NSLog(@"Found the heart rate monitor: %@", localName);
        [self.centralManager stopScan];
        self.polarH7HRMPeripheral = peripheral;
        peripheral.delegate = self;
        [self.centralManager connectPeripheral:peripheral options:nil];
    }
}

这些方法没有被调用。

所以中央（我的iPhone）无法发现外设这是我的葡萄糖设备。

当我从设置 - >蓝牙中搜索设备时找不到设备。

Answer 1

如果永远不会调用centralManager:didDiscoverPeripheral:advertisementData:RSSI:，这可能意味着没有提供CBUUID之一的外围设备。您可以尝试提供nil而不是services-array，并检查是否有可用的外围设备（请勿在生产模式下执行此操作）。

Answer 2

好的，我想在向TaiDoc公司发送电子邮件后我发现了问题，他们告诉我这些设备不支持iPhone蓝牙集成。

我尝试连接Tom-Tom GPS watch并且已成功连接:) 所以我认为问题的问题是硬件问题。

无法在核心蓝牙中发现外设
