ESP32 Arduino: Base64 encoding (using crypto/base64 lib)

In this tutorial we will check how to do the base64 encoding of a string, using the ESP32 and the Arduino core. The tests of this tutorial were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board.

ESP32 Protocol buffers: Encoding a DS18B20 temperature measurement

In this tutorial we will check how to obtain a measurement from the DS18B20 temperature sensor and encode it using protocol buffers. We will be using the ESP32 and the Arduino core. The tests were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board and a waterproof version of the sensor.
