Example code

```
#include <ESP32_LoRa.h>

void setup() {
  Serial.begin(115200);
  LoRa.setPins(5, 18, 19);
  if (!LoRa.begin(915E6)) {
    Serial.println("Could not start LoRa radio");
    while (1);
  }
  Serial.println("LoRa ready");
}

void loop() {
  Serial.println("Sending message");
  LoRa.send("Hello World");
  delay(2000);
}
```
