```cpp
#include <LoRaWAN.h>// Define the LoRaWAN frequency band and spreading factor
LoRaWANFrequency band = EU868;
int spreadingFactor = 7;void setup() {
// Initialize the LoRaWAN module
LoRaWAN.begin();
LoRaWAN.setFrequency(band);
LoRaWAN.setSpreadingFactor(spreadingFactor);
}void loop() {
// Create a LoRaWAN message
char message[] = "Hello, LoRaWAN!";
// Send the message
LoRaWAN.send(message, sizeof(message));
delay(1000);
}
```
### Example 2: Receiving a LoRaWAN Message Using the Mbed FrameworkThis example demonstrates how to receive a LoRaWAN message using the Mbed framework.
```cpp
#include <mbed.h>
#include <LoRaWAN.h>// Define the LoRaWAN frequency band and spreading factor
LoRaWANFrequency band = US915;
int spreadingFactor = 12;int main() {
// Initialize the LoRaWAN module
LoRaWAN.begin();
LoRaWAN.setFrequency(band);
LoRaWAN.setSpreadingFactor(spreadingFactor);
while (true) {
// Wait for incoming data
if (LoRaWAN.available()) {
// Read the received message
char message[256];
int length = LoRaWAN.read(message, 256);
// Print the received message
printf("Received message: %s
", message);
}
}
}
```
### Example 3: Using the P-NUCLEO-LRWAN2 with the LoRaWAN OTAA (Over-the-Air Activation) ProtocolThis example demonstrates how to use the P-NUCLEO-LRWAN2 with the LoRaWAN OTAA protocol.
```cpp
#include <LoRaWAN.h>// Define the LoRaWAN frequency band and spreading factor
LoRaWANFrequency band = AS923;
int spreadingFactor = 10;// Define the OTAA keys
char appEUI[] = "YOUR_APP_EUI_HERE";
char appKEY[] = "YOUR_APP_KEY_HERE";
char devEUI[] = "YOUR_DEV_EUI_HERE";void setup() {
// Initialize the LoRaWAN module
LoRaWAN.begin();
LoRaWAN.setFrequency(band);
LoRaWAN.setSpreadingFactor(spreadingFactor);
// Set the OTAA keys
LoRaWAN.setAppEUI(appEUI);
LoRaWAN.setAppKEY(appKEY);
LoRaWAN.setDevEUI(devEUI);
}void loop() {
// Join the LoRaWAN network using OTAA
if (!LoRaWAN.joinOTAA()) {
Serial.println("Failed to join network");
delay(1000);
} else {
Serial.println("Joined network successfully");
// Send a message to the LoRaWAN network
char message[] = "Hello, LoRaWAN!";
LoRaWAN.send(message, sizeof(message));
delay(1000);
}
}
```
Note: Replace `YOUR_APP_EUI_HERE`, `YOUR_APP_KEY_HERE`, and `YOUR_DEV_EUI_HERE` with your actual OTAA credentials.These examples demonstrate the basic functionality of the P-NUCLEO-LRWAN2 and provide a starting point for developers to build their own LoRaWAN applications.
