esp32-debug-dongle

Purpose

ESP32 dev-kit firmware turning the chip into a WiFi + Bluetooth serial-terminal dongle. Browser-based terminal uses xterm.js served from the ESP's LittleFS; also exposes a classic Bluetooth SPP port for desktop/mobile terminal apps. Multi-port (internal debug / USB / external Serial1) with on-the-fly baud-rate switching.

Type

ESP32 PlatformIO firmware. #embedded, #firmware, #iot, #service.

Dependencies

External: PlatformIO espressif32 + Arduino framework, xterm.js (bundled in LittleFS), Bluetooth SPP stack (classic BT — needs a WROOM-style ESP32, NOT S2/S3/C3).
Internal: complementary tool to ESP32 Sh3d projects — Sh3dNb, Sh3dController, Sh3dStick, Doxy — when serial access is awkward.

Notable

Uses a huge_app.csv partition (3 MB app, 1 MB FS, no OTA) — swap to min_spiffs.csv if OTA is needed.
Classic Bluetooth requirement is a hard constraint on target hardware.
