“Following suggestions from my YouTube channels followers, we will talk about the ESP32 LoRa again today. However, this time well discuss sending and receiving data by the same device. In this situation, an ESP32 LoRa, the Master, will send a packet warning that it wants to receive the data, while another device, the Slave, will wait for the command to send the data back to the Master. This is unlike other videos I’ve done that featured an ESP32 LoRa as Sender and another as Receiver, as today we will have the same device, the Master, that will send and receive data.”
