I will develop iot firmware for esp32 and stm32

I develop and debug embedded IoT firmware for microcontroller-based devices, with a focus on sensor integration, telemetry framing, and reliable device communication.

My services include:

• Embedded C/C++ firmware development and debugging
• Sensor integration and data validation
• Telemetry framing using JSON or custom data formats
• MQTT and HTTP/HTTPS communication
• TCP/IP socket communication
• UART, SPI, and I2C integration
• Bluetooth Low Energy (BLE) communication for supported hardware
• Connection recovery, error handling, and firmware testing

I work with embedded platforms such as STM32 and ESP32, using suitable development frameworks and libraries for the target hardware.

Please share your microcontroller, development environment, requirements, communication protocol, and existing code (if available) before ordering. I will review the scope and confirm feasibility.

Deliverables can include source code, build instructions, and test notes. PCB design, mobile applications, complete cloud backends, dashboards, and production certification are not included unless separately agreed.
