问题描述

 private async void CharacteristicsReadButton_Click()
{
// BT_Code:使用Uncached从设备读取实际值。
GattReadResult result = await selectedCharacteristic.ReadValueAsync(BluetoothCacheMode.Uncached);
if(result.Status == GattCommunicationStatus.Success)
{
string formattedResult = FormatValueByPresentation(result.Value,presentationFormat);

rootPage.NotifyUser($" Read result:{formattedResult}",NotifyType.StatusMessage);

}
else
{
rootPage.NotifyUser($" Read failed:{result.Status}",NotifyType.ErrorMessage);
}



我正面临读取值更改的问题。我用我的rfduino设置了mpu5060,所以每当我的rfduino移动时,它会在我的Arduino串口显示器上显示角度。



我的c#,我可以阅读当我按下"阅读"时的值按钮。但是如果我的值(角度)发生变化,它将不会自动更新以通知用户。我必须手动点击"阅读"按钮再次更改。  如何让
自动更新?

解决方案

private async void CharacteristicReadButton_Click()
        {
            // BT_Code: Read the actual value from the device by using Uncached.
            GattReadResult result = await selectedCharacteristic.ReadValueAsync(BluetoothCacheMode.Uncached);
            if (result.Status == GattCommunicationStatus.Success)
            {
                string formattedResult = FormatValueByPresentation(result.Value, presentationFormat);
                
                rootPage.NotifyUser($"Read result: {formattedResult}", NotifyType.StatusMessage);
                
            }
            else
            {
                rootPage.NotifyUser($"Read failed: {result.Status}", NotifyType.ErrorMessage);
            }
        

I'm facing a problem with the read value change. I have setup mpu5060 with my rfduino, so whenever my rfduino moved, it will display the angle on my Arduino serial monitor.

for my c#, I can read the value when I press the "read" button. But if my value(angle) change, it will not auto update to notify user. I have to manually click the "read" button again to change. How do I make it auto update ?
