Buttoning up the code. But it’s still pretty messy.
And managed to implement MeshCore for it!

BC I have copy pasted a lot of function blocks the chode is glued together with a duck tape

So after getting the ptt -> STT -> TTS working I have though on how to implement the MC functionality. SO I’ve began with getting familiar with the meshcore library by running the included sample sketch which should send a message to the first contact. I ran that and didn’t see anything, after that I made sure that my other device was on top and it worked!
After that I’ve let ChatGPT to do implement a sample code that will let me communicate via the terminal. And it no workie, fixed it and it works great!

Then implemented to the main codebase with copilot. The prompt was the intended function along with a few more things like automatically playing tts file.
