Ombr Firmware

ESP32 firmware for the Ombr device using ESP-IDF and CMake.

Prerequisites

• ESP-IDF v5+ installed and exported
• ESP32 toolchain (installed through ESP-IDF tools)

Getting Started

From this folder:

idf.py set-target esp32
idf.py build

Flash and Monitor

idf.py -p <PORT> flash monitor

Example port on macOS: /dev/cu.usbserial-xxxx

Notes

• Main firmware sources are in main/.
• Build artifacts are generated in build/.
• The connectivity component wraps Wi-Fi station control, raw TCP client sends, and a BLE peripheral GATT service.

Project Structure

• components/protocol/: Packet building, encoding, decoding, and frame validation
• components/driver/: Direct GPIO hardware wrappers for LEDs and outputs
• components/connectivity/: Wi-Fi and BLE wrappers for network and peripheral control
• main/app_main.cpp: Firmware entry point for provisioning mode
• CMakeLists.txt: Top-level ESP-IDF project definition
