M5Stack LoRaWAN library (available on GitHub)Code Examples### Example 1: Simple LoRa Transmitter (Point-to-Point Communication)This example demonstrates how to use the M5 Stack LoRa Module as a transmitter, sending data to a remote LoRa receiver.
```cpp
#include <M5Stack.h>
#include <LoRaWAN.h>// Set up LoRa module
LoRaWAN lorawan;void setup() {
// Initialize M5 Stack
M5.begin();
// Initialize LoRa module
lorawan.begin(433E6, 7, 1, 8, 8, 14);
lorawan.setSpreadingFactor(7);
lorawan.setBandwidth(250E3);
}void loop() {
// Create a LoRa packet
LoRaPacket packet;
packet.addPayload("Hello, LoRa!");
// Send the packet
lorawan.send(packet);
// Wait for 1 second before sending the next packet
delay(1000);
}
```
### Example 2: LoRaWAN Node (OTAA Activation)This example demonstrates how to use the M5 Stack LoRa Module as a LoRaWAN node, utilizing Over-The-Air Activation (OTAA) to join a LoRaWAN network.
```cpp
#include <M5Stack.h>
#include <LoRaWAN.h>// Set up LoRa module
LoRaWAN lorawan;// OTAA parameters
const char appEui = "YOUR_APP_EUI";
const char appKey = "YOUR_APP_KEY";
const char deviceEui = "YOUR_DEVICE_EUI";void setup() {
// Initialize M5 Stack
M5.begin();
// Initialize LoRa module
lorawan.begin(433E6, 7, 1, 8, 8, 14);
// OTAA activation
lorawan.setOtaa(appEui, appKey, deviceEui);
lorawan.join();
}void loop() {
// Check if we've joined the network
if (lorawan.getJoinStatus() == 1) {
Serial.println("Joined the network!");
} else {
Serial.println("Not joined yet...");
}
// Wait for 10 seconds before checking again
delay(10000);
}
```
Note: Replace `YOUR_APP_EUI`, `YOUR_APP_KEY`, and `YOUR_DEVICE_EUI` with your actual LoRaWAN application EUI, application key, and device EUI, respectively.These code examples demonstrate the basic usage of the M5 Stack LoRa Module for ESP32 DIY Development Kit. You can modify and expand upon these examples to create more complex IoT projects, such as sensor monitoring, asset tracking, or smart home automation.
