I will write custom esp32 firmware with wifi or ble integration

Need stable, low-power, and secure firmware for your ESP32 project? Whether you are building a commercial IoT product, a smart home device, or a wireless sensor network, I will write the custom C/C++ firmware you need.

I am an embedded systems engineer experienced in maximizing the dual-core potential of the ESP32, ESP32-S, and ESP32-C series chips using both Arduino IDE and ESP-IDF frameworks.

What I Can Build For You:

• Wi-Fi Connectivity: HTTP/HTTPS, WebSockets, OTA (Over-The-Air) updates, and MQTT clients for AWS IoT, Azure, Firebase, or custom brokers.
• BLE / Bluetooth: Custom GATT services/characteristics, BLE beacons, security pairing, and seamless data exchange with mobile apps.
• Power Optimization: Deep sleep and light sleep configurations for long-lasting, battery-powered IoT nodes.
• Peripherals & Protocols: High-performance drivers for sensors and modules via I2C, SPI, UART, ADC, and PWM.

What You Will Receive:

• Highly optimized, production-ready, non-blocking C/C++ code.
• Clear code documentation and peripheral wiring guides.

IMPORTANT: IoT projects are highly hardware-dependent. Please message me BEFORE ordering to discuss your schematics, selected modules, and cloud requirem
