In this tutorial we will learn how to use the cpplinq pairwise operator. This operator allows to group adjacent elements of an array into pairs. 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 using a DFRobot’s ESP8266 FireBeetle board.
