Following several example of code posted here to print to bluetooth printer. VS 2019, LinkOS_Xamarin_SDK 1.20
Install app on Zebra TC 51, paired with ZQ511

When printing sending ZPL to printer, is taking about 10 to 15 seconds to print , the line ConnectionBuilder.Current.Build("BT:" + address) is taking about 6+ seconds

I crated a test print function below , how can i get the IConnection thePrinterConn = ConnectionBuilder.Current.Build("BT:" + address); to execute faster ?

private void Print_Clicked(object sender, EventArgs e)
{
var watch = new System.Diagnostics.Stopwatch();
watch.Start();

string address = Preferences.Get("printer_key", "default_value"); // 1 ms

IConnection thePrinterConn = ConnectionBuilder.Current.Build("BT:" + address); // 6219 ms

// var thePrinterConn = ConnectionBuilder.Current.Build("BT:" + address); // 6219 ms

// tested withiut "BT:" -
//var thePrinterConn = ConnectionBuilder.Current.Build(address); // 17164 ms 17.164 sec

watch.Stop();
warningLabel.IsVisible = true;
warningLabel.Text = $"Execution connectbuild Time: {watch.ElapsedMilliseconds} ms";

//open connection
thePrinterConn.Open(); // 1216 ms - 1.2 sec

string zpl = "^XA^FO45,25^BY1^BCN,127,N,N,,N,A^FD1234567890^FS^FT29,173^CI0^A0N,20,27^FDTest5678901Test^F^PQ1^XZ";
// Send the data to printer as a byte array.
thePrinterConn.Write(System.Text.Encoding.ASCII.GetBytes(zpl)); // 494 ms .5 sec

// Close

thePrinterConn.Close(); // 920 ms 1 sec

/// total 17272

}
