LoRaWAN ESP32-S3 Dev Board

The article provides a step-by-step guide for first-time users of the ESP32 development board, detailing how to configure Arduino IDE, select the appropriate board settings, and execute a simple LED blinking program. It covers essential configurations such as USB CDC settings and partition schemes, ensuring a smooth setup process for beginners.

This sample code connects to the LoRaWAN network in OTAA (Over-The-Air Activation) mode. It sends data (the string "DFRobot") every 10 seconds, supports receiving downlink data and printing it, and automatically retries if the connection fails. For more sample code, please refer to the "DFRobot_LoRaWAN_ESP32S3\examples" directory.

This sample code connects to the LoRaWAN network in ABP (Activation By Personalization) mode (you can enter any DEVEUI when adding the device). It sends data (the string "DFRobot") every 10 seconds and supports receiving downlink data for printing.

This sample code connects to the LoRaWAN network in OTAA mode, sends data (the string "DFRobot") every 10 seconds, and uses the screen to display network connection, transmission, and reception status.

This sample code connects to the LoRaWAN network in OTAA mode. It sends data (the string "DFRobot") every 10 seconds, receives downlink messages (with ACK or data), uses the screen to display network connection, transmission and reception status, and supports the identification and processing of wake-up sources (button wake-up).

Transmitter Side: Sends data to the receiver and displays the number of transmissions on the screen. Receiver Side: Receives data from the transmitter and displays the number of data receptions on the screen.

This sample code connects to the LoRaWAN network in OTAA mode. It reads data from the SHT31 temperature and humidity sensor (I2C address: 0x45) every 30 seconds, displays the data on the screen, sends the data to the gateway, and then enters sleep mode. The main controller can be proactively woken up via a button (connected to IO18) to collect and send data.
