OpenMQTTGateway LoRa Node Example
This repository contains an example of a LoRa node program designed for the ESP32 platform. The program reads the internal temperature of the ESP32, packages the data into a JSON format, and sends it over LoRa.
Features:
- Uses an SX12XX LoRa module.
- Displays packet sending status and temperature data on an SSD1306 OLED display.
- Sends the ESP32's MAC address as the node ID.
- Sends temperature data in Celsius.
Hardware Requirements:
- ESP32 development board.
- SX12XX LoRa module.
- SSD1306 OLED display.
Pin Configuration:
- SCK - GPIO5
- MISO - GPIO19
- MOSI - GPIO27
- SS - GPIO18
- RST - GPIO14
- DI0 - GPIO26
Setup:
Hardware Setup:
Connect the SX1278 LoRa module and the SSD1306 OLED display to the ESP32 according to the pin configuration. Ensure that the OLED display is powered correctly.
Software Setup:
- Clone this repository.
- Open the provided node program with PlatformIO
- Upload the program to your ESP32.
Usage:
Power on the ESP32. The OLED display will show the status of the packet being sent and the current temperature reading. The built-in LED on the ESP32 will blink once every time a packet is sent. Monitor the serial output (at 115200 baud rate) to see the JSON formatted data being sent.
Data Format:
The data is sent in the following JSON format:
{
"model": "ESP32TEMP",
"id": "ESP32_MAC_ADDRESS",
"tempc": "TEMPERATURE_IN_CELSIUS"
}
Troubleshooting:
LoRa Initialization Failed: Ensure that the SX1278 LoRa module is connected correctly and powered on. OLED Display Not Working: Check the connections and ensure that the display is powered correctly. No Temperature Data: Ensure that the ESP32's internal temperature sensor is functional. Contributing: Feel free to contribute to this example by opening issues or submitting pull requests.
