Hi everyone!
I wanted to share a tool I’ve been working on called mpair (MicroPython Air). It’s designed to solve the common issue of losing REPL or file access over Wi-Fi when a script is already running in a loop.
The Problem:
Standard WebREPL can be tricky to break into if your main.py is busy, and sometimes you just need a "hard" way to reset the board or swap files without a serial cable.
The Solution:
mpair uses two dedicated ports to manage the ESP32-C3:
UDP (Port 8267): Handles "Out-of-Band" commands like reset or boot mode via a background timer. It works even while your main code is executing.
TCP (Port 8268): A lightweight server for file operations and remote exec() execution.
Key Features:
CLI Tool: Installable via pip. Just type mpair from your terminal.
No Serial Needed: Once the server is on the flash, you can manage everything over Wi-Fi.
Lightweight: Designed specifically with the ESP32-C3 in mind.

I'd love to hear your thoughts or if anyone has ideas for more OOB commands!
