seeking for help related to data communication with a uart module.
I don't believe you can use UART at the same time you're trying to upload something. One solution would be to use software serial on different pins for your serial communication duties. https://docs.arduino.cc/learn/built-in-libraries/software-serial/
Also, I'm not sure how the pin with an onboard LED affects things, so you may want to avoid that. I had some problems with that before, though it could be how I had it programmed.
