我正在嘗試爲我的手機編寫一個應用程序,該應用程序連接到BLE設備。c#UWP BluetoothLEDevice.FromIdAsync System.IO.FileNotFoundException
該設備已配對,我編輯了appxmanifest以啓用藍牙功能。
但是當我運行應用程序,下面的代碼,
await BluetoothLEDevice.FromIdAsync(deviceInfo.Id);
導致異常拋出:「System.IO.FileNotFoundException」在mscorlib.ni.dll
沒有人有一個想法我做錯了什麼?
謝謝!
var deviceList = await DeviceInformation.FindAllAsync(GattDeviceService.GetDeviceSelectorFromUuid(GattServiceUuids.GenericAccess), null);
int count = deviceList.Count();
if (count > 0)
{
var deviceInfo = deviceList.Where(x => x.Name == "XC-Tracer").FirstOrDefault();
if (deviceInfo != null)
{
if (deviceInfo.IsEnabled)
{
var bleDevice = await BluetoothLEDevice.FromIdAsync(deviceInfo.Id);
var deviceServices = bleDevice.GattServices;
}
}
}
