在核心蓝牙中无法发现外围设备

Question

我有iPhone应用程序，我想与蓝牙设备连接以获得葡萄糖测量值。 您可以从这里找到设备。

在阅读了有关Core Bluetooth的Apple文档之后，我开始阅读这些教程 。 此外，我得到了服务ID的蓝牙设备从这些链接在这里

因此，在了解了基础知识之后，我便开始像本教程中那样编写代码。

这些是我的代码：

#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的委托

我收到有关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日志： CoreBluetooth BLE hardware is powered on and ready.

但是我没有收到有关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。

因此，中央（我的iPhone）无法找到作为我的葡萄糖设备的外围设备。

从设置->蓝牙搜索设备时找不到设备。

Answer 1

如果从不调用centralManager:didDiscoverPeripheral:advertisementData:RSSI:则可能意味着没有外围设备具有提供的CBUUID之一。 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（不要在生产模式下执行此操作）。

Answer 2

好的，我认为在向TaiDoc公司发送电子邮件后发现了问题，他们告诉我这些设备不支持i​​Phone蓝牙集成。

我试图与Tom-Tom GPS手表连接，并且连接成功:)因此，我认为这个问题是硬件问题。
