Code Examples

### Example 1: Basic Telemetry Transmission using Arduino

This example demonstrates how to use the 3DR Radio Telemetry module with an Arduino board to transmit telemetry data from a drone to a ground station.

Transmitter Code (Arduino)
```c
#include <RF22.h>

RF22 radio;

void setup() {
  radio.init();
  radio.setFrequency(433.0);
  radio.setTxPower(RF22_TXPOWER_20DBM);
}

void loop() {
  char telemetryData[] = " Drone Telemetry: Altitude=100m, Speed=50km/h";
  radio.send((uint8_t )telemetryData, strlen(telemetryData));
  delay(100);
}
```
Receiver Code (Arduino)
```c
#include <RF22.h>

RF22 radio;

void setup() {
  radio.init();
  radio.setFrequency(433.0);
}

void loop() {
  if (radio.available()) {
    uint8_t buf[RH_RF22_MAX_MESSAGE_LEN];
    uint8_t len = RH_RF22_MAX_MESSAGE_LEN;
    radio.recv(buf, &len);
    Serial.println((char )buf);
  }
}
```
### Example 2: Bi-Directional Communication using Python and Raspberry Pi

This example demonstrates how to use the 3DR Radio Telemetry module with a Raspberry Pi and Python to establish bi-directional communication between a drone and a ground station.

Transmitter Code (Raspberry Pi)
```python
import RPi.GPIO as GPIO
from rfm22 import RFM22

# Initialize GPIO and RFM22 module
GPIO.setmode(GPIO.BCM)
rfm22 = RFM22('/dev/spidev0.0', 1000000)

# Set frequency and transmission power
rfm22.set_frequency(433.0)
rfm22.set_tx_power(20)

while True:
    # Send telemetry data
    telemetry_data = " Drone Telemetry: Altitude=100m, Speed=50km/h"
    rfm22.send(telemetry_data.encode())

# Wait for response from receiver
    response = rfm22.recv()
    if response:
        print("Received response:", response.decode())
    time.sleep(0.1)
```
Receiver Code (Raspberry Pi)
```python
import RPi.GPIO as GPIO
from rfm22 import RFM22

# Initialize GPIO and RFM22 module
GPIO.setmode(GPIO.BCM)
rfm22 = RFM22('/dev/spidev0.0', 1000000)

# Set frequency
rfm22.set_frequency(433.0)

while True:
    # Receive telemetry data
    telemetry_data = rfm22.recv()
    if telemetry_data:
        print("Received telemetry data:", telemetry_data.decode())

# Send response back to transmitter
    response = "Ground station received telemetry data."
    rfm22.send(response.encode())
    time.sleep(0.1)
```
