uwp - 不断收到 BLE UWP Unreachable 错误

Question

我一直在尝试使用 UWP 枚举和连接到 BLE 设备。我的 BLE 服务器是运行 Windows IOT 的 Raspberry Pi。
我在笔记本电脑上运行 BLE 客户端。但是，当我尝试枚举 Raspberry Pi 上的服务时，我通常会遇到无法访问的错误。在下面的代码中，serviceResult.Status 通常是无法访问的。 Raspberry PI 就放在我的笔记本电脑旁边。

        device = await BluetoothLEDevice.FromBluetoothAddressAsync(bleDeviceAddress);
        GattDeviceServicesResult serviceResult = await device.GetGattServicesForUuidAsync(guid);
        if (serviceResult.Status == GattCommunicationStatus.Success)

Answer 1

尝试未缓存模式:

GattDeviceServicesResult serviceResult = await bleDevice.GetGattServicesForUuidAsync(guid, BluetoothCacheMode.Uncached);
