COM Port Proxy (for Nextion/MCU development/debugging)

I just realized that this tool I made might be helpful for people in here. I use it frequently when working with MCUs and Nextion panels.

By using my tool I keep both the MCU and Nextion panel connected to separate COM-ports on my PC. This way I can program them separately and when I want them to communicate, I just connect them through the proxy tool. It’s also possible to inspect all the communication between the MCU and the Nextion. I find it extremely useful for debugging.


Video example for data inspection:

Open source on GitHub of course:


This looks super handy. It should make switching in the Nextion Simulator easy too! Adding this to my toolset for sure, thanks for sharing this @hag!
