Get the live data on TCP server from UWP (UPDATED)

Question

Below is one method that basically sends the data to TCP Server.

         UPDATE BEGINS HERE: 
 //////////////////////////////////
 private string FormatValueBy         


        

Answer 1

while (true)
{
    await streamWriter.WriteLineAsync(data);
    await streamWriter.FlushAsync();
}

The while(true) will keep repeating, meaning that it will always send 'data' at its current value. This is what causes your issue.

In my opinion, you should keep a connection to your TCP server open outside of your 'TrySend' method, and use this method only to send the data. This way you won't need to use this loop.

EDIT :

Try this :

private async void CharacteristicReadButton_Click()
    {
    while(true)
    {
            // 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);

                //string formattedResult = FormatValueByPresentation(result.Value, presentationFormat);
                //rootPage.NotifyUser($"Read result: {formattedResult}", NotifyType.StatusMessage);
            }
            else
            {
                rootPage.NotifyUser($"Read failed: {result.Status}", NotifyType.ErrorMessage);
            }
        }
    }
