Everybody talks about LoRa to bridge long distances. Today we will have a look into how we can extend the range of a normal ESP32 using the Arduino IDE. You will also learn how to do that and stay legal. And maybe we even can reduce the power consumption of the chip if we do not need the extended range. And what we learn, we can also be used for our ordinary Wi-Fi network. Unfortunately, it does not work with the ESP8266.
