Espressif Mesh Development Framework

Espressif Mesh Development Framework

“Espressif Systems Mesh Development Framework (ESP-MDF) is the official mesh development framework for the ESP32 chip. ESP-MESH Overview With the development of the Internet of Things, the scale of networked devices is rapidly expanding. However, the traditional senario of wireless networking implements a point-to-point or point-to-multipoint star topology. All terminal nodes must be connected to the hub (router …

ESP32 LoRa With Arduino IDE: Send and Receive TX RX

ESP32 LoRa With Arduino IDE: Send and Receive TX RX

“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 …
