Could you please simplify it ?
I can't see how.
Does the application that is sending data to the Arduino have the capability to receive data from the Arduino and display it to you?
The application is only sending not receiving. Arduino is only receiving and do some calculations all i want is to see what arduino is receiving but i can't do it through serial monitor because the port is in use when i am running the code from c# so i am asking you is there another way to see how can i see what arduino is receiving?
