BLE 设备不断连接/断开连接

Question

我正在使用我的应用程序与BLE device 连接并跟踪连接状态，如下所示

//Called when device is connected
- (void)centralManager:(CBCentralManager *)central didConnectPeripheral:(CBPeripheral *)peripheral
{
    [self.activePeripheral discoverServices:nil];
    if (peripheral.isConnected)
    {
        currentStatusLbl.text = [NSString stringWithFormat:@"Connected"];
    }
}

//Called if device disconnects
-(void)centralManager:(CBCentralManager *)central didDisconnectPeripheral:(CBPeripheral *)peripheral error:(NSError *)error
{
    currentStatusLbl.text = [NSString stringWithFormat:@"Disconnected"];
    [self.centralManager connectPeripheral:peripheral options:nil]; //Connect again
}

//Device found, request connection
- (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI
{
     NSString *localName = [advertisementData objectForKey:CBAdvertisementDataLocalNameKey];
     devieName.text = [localName stringByAppendingString:@" Found"];
     if (localName && ![localName isEqual:@""])
     {
         [self.centralManager stopScan];
         self.activePeripheral = peripheral;
         self.activePeripheral.delegate = self;
         [self.centralManager connectPeripheral:peripheral options:nil];
     }
}

运行7.1.1 的iPhone 5 面临的问题是标签上的状态不断在连接和断开之间切换。状态栏上的蓝牙图标确认了这一点（继续显示连接和断开状态）。我尝试打开/关闭设备（BLE 设备和手机的硬重置）。还打开/关闭蓝牙。但我仍然遇到这个问题。

我也遵循here in this question 提供的建议，但没有运气。

如果我做错了什么或者这是操作系统问题，有人可以告诉我吗？

谢谢。

写 [activePeripheral 保留];在 didDiscoverPeripheral 的 if 条件中。 希望对你有帮助
