```cpp
#include <SPI.h>
#include <LoRa.h>#define LORA_CS 10
#define LORA_RST 9
#define LORA_DIO0 2void setup() {
Serial.begin(9600);
LoRa.setPins(LORA_CS, LORA_RST, LORA_DIO0);
if (!LoRa.begin(868E6)) { // 868MHz frequency
Serial.println("Starting LoRa failed!");
while (1);
}
Serial.println("LoRa started.");
}void loop() {
Serial.print("Sending packet: ");
Serial.println("Hello, LoRa!");
LoRa.beginPacket();
LoRa.print("Hello, LoRa!");
LoRa.endPacket();

```Receiver Code
```cpp
#include <SPI.h>
#include <LoRa.h>#define LORA_CS 10
#define LORA_RST 9
#define LORA_DIO0 2void setup() {
Serial.begin(9600);
LoRa.setPins(LORA_CS, LORA_RST, LORA_DIO0);

Serial.println("Starting LoRa failed!");
while (1);
}
Serial.println("LoRa started.");
}void loop() {
int packetSize = LoRa.parsePacket();
if (packetSize) {

```### Example 2: FSK Communication using Raspberry PiIn this example, we will demonstrate a basic FSK communication between two LoRa-Ra-01 modules using Raspberry Pi and Python.Transmitter Code
```python
import RPi.GPIO as GPIO
import spidev# Initialize GPIO and SPI
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT) # CE pinspi = spidev.SpiDev()
spi.open(0, 0)
spi.max_speed_hz = 1000000# Set FSK modulation
spi.xfer([0x80, 0x03]) # FSK mode
spi.xfer([0x90, 0x01]) # FSK frequency deviationwhile True:
# Send FSK packet
spi.xfer([0x80, 0x01]) # Start transmission
spi.xfer(b'Hello, FSK!')
spi.xfer([0x80, 0x00]) # End transmission
time.sleep(1)
```Receiver Code
```python
import RPi.GPIO as GPIO
import spidev# Initialize GPIO and SPI
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT) # CE pinspi = spidev.SpiDev()
spi.open(0, 0)
spi.max_speed_hz = 1000000# Set FSK modulation
spi.xfer([0x80, 0x03]) # FSK mode
spi.xfer([0x90, 0x01]) # FSK frequency deviationwhile True:
# Receive FSK packet
rx_data = spi.xfer([0x80, 0x02]) # Start reception
print(rx_data.decode())
time.sleep(1)
