ESP32 IoT WiFi Firmware
Budget: ₹12,500 – ₹37,500 INR
I’m building a small IoT device around an ESP32 and need concise, well-structured firmware that brings reliable WiFi connectivity online. The goal is straightforward: power up, join a predefined network (with fallback smart-config or captive portal for first-time setup), then expose a simple REST or MQTT interface so the rest of my stack can push and pull data.
The code may be written in either the ESP-IDF or Arduino framework—whichever you’re most productive with—as long as it’s cleanly commented and easy for me to compile and flash from macOS. I will provide the SSID, credentials, and endpoint details once we start.
Deliverables
• Source code and project files
• Brief README covering build steps, pin assignments (if any), and how to change WiFi settings
• A quick test video or screenshots showing the board connecting and responding to a sample request
I’ll flash and run the build on my own hardware; payment clears once it connects, publishes a test payload, and survives a power cycle without user intervention.
