ESP32 Tutorials

Postby anteph » Mon May 08, 2017 2:16 pm


I've been writing some tutorials about the ESP32 at my blog, which are available in the link bellow. I'm covering some basic topics, such as how to connect to a WiFi network or how to connect to MQTT broker, and some more advanced ones, such as using FreeRTOS in the Arduino IDE environment.

Hope it helps others.

Best regards,
Nuno Santos
