ESP32 Websocket server: Sending binary frame to client

In this tutorial we will check how to send binary frames to a client that connects to websocket endpoint from a HTTP server running on the ESP32. The tests 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.

ESP32 / ESP8266 Arduino: Protocol Buffers

In this tutorial we will learn how to get started using Protocol Buffers with the Arduino core, both running on the ESP32 and on the ESP8266. The tests on the ESP32 were performed using a DFRobot’s ESP-WROOM-32 device integrated in a ESP32 FireBeetle board. The tests on the ESP8266 were performed on a DFRobot’s ESP8266 FireBeetle board.

ESP32 / ESP8266 Arduino: Printing numbers to serial in different bases

In this tutorial, we will check how we can print numbers to the serial port using different bases, more specifically in binary, octal and hexadecimal. The tests on the ESP32 were performed using a DFRobot’s ESP-WROOM-32 device integrated in a ESP32 FireBeetle board. The tests on the ESP8266 were performed on a DFRobot’s ESP8266 FireBeetle board.
