Example code

```cpp
#include <LoRa.h>

void setup() {
  Serial.begin(9600);
  LoRa.setPins(5, 19, 23);
  if (!LoRa.begin(915E6)) {
    Serial.println("LoRa init failed");
    while (1);
  }
}

void loop() {
  Serial.println("Sending packet");
  LoRa.send("Hello World");
  delay(5000);
}
```

Mini project

Build an environmental monitoring system with a temperature and humidity sensor. Connect the sensor to the ESP32 and send data to a LoRaWAN gateway.

Common mistakes

• Forget to correctly configure the LoRaWAN parameters.
• Incorrectly connect the key to the ESP32 board.
• Lack of a stable connection with the LoRaWAN gateway.
• Insert incorrect or incomplete code.

Recommended accessories

• Temperature and humidity sensors
• LoRaWAN gateway
• LoRaWAN monitoring software
• High-quality USB cable
