# 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:
|
|
|
|
```json
|
|
{
|
|
"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.
