FAQ
Do you use ESP-IDF or the Arduino Framework for ESP32?
I support both! I recommend ESP-IDF with FreeRTOS for production-grade, low-latency, or memory-critical applications. For rapid prototyping or simpler IoT builds, the Arduino framework works great.
Can you integrate my ESP32 device with Blynk, AWS IoT, or a custom web dashboard?
Yes! I set up secure MQTT over TLS, HTTP REST APIs, and WebSocket protocols to connect your device seamlessly to platforms like AWS IoT Core, Blynk 2.0, Firebase, or custom dashboards.
Can you create touchscreen GUIs for ESP32 displays using LVGL?
Yes. I build responsive GUIs using LVGL (v8/v9) and SquareLine Studio on ESP32-S3 display boards (RGB, SPI, parallel, or round displays) with smooth PSRAM buffering.
How do users connect the ESP32 to their home Wi-Fi network?
I implement custom Wi-Fi provisioning via a Captive Portal (Access Point mode) or BLE provisioning, allowing users to select their network and enter passwords directly from a phone or web browser.
