Hi,
So I am creating a 2 project simulation using proteus and Arduino ide. A controller and the device. What I am trying to do is to transmit and received a string to the controller and device. When I did a one-way communication, it works fine. However, if I did a 2-way it doesn't work. I have tried all sorts of ways in what I am capable of but I'm still having a hard time solving the problem any suggestions. I tried using the software serial along with the hardware serial but it still doesn't work Here's what I have so far sorry if it's a bit messy. Any help would be appreciated. Thanks.
I am using the Atmega328P microcontroller. But I am making it behave like an arduino uno
I wrote the code here in the post and included in the attachment
I also included in the attachment the simulation circuit for the device and controller
