ios - CoreBluetooth AdvertisementData 不包含 CBAdvertisementDataLocalNameKey？

Question

我目前正在构建一个我想扫描可用设备的 CoreBluetooth 应用程序，问题是“didDiscoverPeripheral”中的 AdvertismentData 字典不包含 CBAdvertisementDataLocalNameKey - 它只包含 CBAdvDataChannel 和 CBAdvDataIsConnectable。这意味着我无法识别我的 BLE 设备。

有趣的是，Lightblue 应用程序(iOS BLE 扫描仪)能够显示名称，因此大概能够访问“CBAdvertisementDataLocalNameKey”。

有谁知道我做错了什么？我真的为此焦头烂额!

这是我的代码的基本示例:

-(void)scan
{

    NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber  numberWithBool:YES], CBCentralManagerScanOptionAllowDuplicatesKey, nil];
    [mCentralManager scanForPeripheralsWithServices:nil options:options];
}

- (void)centralManager:(CBCentralManager *)central didConnectPeripheral:(CBPeripheral *)peripheral
{
}

- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI
{
    for(id key in advertisementData)
        NSLog(@"key=%@ value=%@", key, [advertisementData objectForKey:key]);
}

Answer 1

尝试使用已发现外围设备的名称属性，而不是使用广告数据:

- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI
{
    NSString    *thePeripheralName  = peripheral.name;
}
