I will develop esp32 firmware with wifi, ble, mqtt, and freertos
About this Gig
Are you looking for reliable ESP32 firmware for your IoT project?
I specialize in developing production-quality embedded firmware for ESP32 devices using ESP-IDF and FreeRTOS.
What I deliver:
- Custom firmware with WiFi, BLE, or MQTT connectivity
- Sensor/module integration and driver development
- Clean, documented, maintainable C/C++ source code
- OTA update support for production deployments
I work with:
ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6
Whether you need a quick prototype or a production-ready system, I can help. Message me with your project details and I'll get back to you within a few hours.
FAQ
What information do you need to start?
A brief description of your project — what hardware you're using, which sensors/modules, and what the device should do. Schematic or wiring diagram is helpful but not required.
Which ESP32 boards do you support?
All ESP32 variants — ESP32, S2, S3, C3, C6. I work with ESP-IDF (not just Arduino), so I can handle advanced features like BLE mesh, deep sleep, and dual-core tasks.
Do you provide the source code?
Yes, all packages include full source code. You own it completely after delivery.
Can you help with an existing project that needs fixing?
Absolutely. Send me your current code and describe the issue. I'll review it and let you know what's needed before you place an order.
Do you build hardware or just firmware?
Firmware only. I write the software that runs on your ESP32 board. If you need help selecting components, I offer that as an add-on.
