ESP32 / ESP8266 Protocol Buffers: messages with strings

In this tutorial we will check how to use strings in our protobuf messages, using Nanopb and the Arduino core, running both 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 MicroPython: String split method

The objective of this post is to explain how to use the split method to separate strings in sub-strings accordingly to a given separator string. This tutorial was tested both 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.
