What's the status of the Arduino's LED?
You need to power the display first, then the Arduino.
Do you have an Arduino Uno and can you try with it?
Is the Arduino's LED flashing when you try to connect with the GUI tool?
Which operating system are you using?
Did you select the correct COM port?

It flashes once every retry. The display is powered on previously. From the i2c scan I can see bunch of devices on the display board. No, I don't have arduino UNO to try. I'm using win10 64-bit. Yes, I do selected the correct COM port

Succeeded with RPI but not with arduino way too many issues
from rtd266xflash.
Ok I can reproduce the problem with a SparkFun Pro Micro. The GUI tool won't connect.
But luckily I found a solution. You need to add
_comPort.DtrEnable = true;
_comPort.RtsEnable = true;
in FormArduino.cs, function btnConnect_Click() after _comPort.Handshake = Handshake.None;
Or apply this patch:
diff --git a/RTD266xFlash/RTD266xFlash/Forms/FormArduino.cs b/RTD266xFlash/RTD266xFlash/Forms/FormArduino.cs

Can you please try this and report back?

I guess I should compile the gui again?

Recompiled with the patch applied and now is working. Thanks.

Great :) I've released an updated version with the fix.
