All set correctly here! I have tried with 2 different boards. I used before flowcode with arduino with success I do not know why now displays this error message!
I have changed the arduino Mega 2560 to Mega 2560 R3 and it worked .. so I guess was my fault!
How ever I want to program an arduino UNO wifi, which board should I choose to be correct? Because the target controller list does not include UNO wifi!
Will try that! One important thing though if you can help me in this post.
> Arduino UNO wifi has embedded the ESP8266 and as far as I know in order for the arduino to communicate with esp8266 uses different coding and method and probably uses different UART.
Do you have any recommendations for that ? How to design the flowcode?
