Code Examples
### Example 1: Python Script for Reading Vehicle Data using Pyserial and Python-OBD2 Libraries
This example demonstrates how to use the Mini elm327 Bluetooth OBD2 component with a Python script to read vehicle data, including engine speed, throttle position, and coolant temperature.
Prerequisites:
Python 3.x installed on your computer
Pyserial library installed using `pip install pyserial`
Python-OBD2 library installed using `pip install python-obd2`
Code:
```python
import serial
import obd
# Establish a connection to the Mini elm327 Bluetooth OBD2 device
ser = serial.Serial('COM3', 38400, timeout=1) # Replace COM3 with your device's serial port
# Create an OBD2 connection object
conn = obd.OBDConnection(ser)
# Read engine speed (RPM)
rpm = conn.query(obd.commands.RPM)
print("Engine Speed (RPM):", rpm.value)
# Read throttle position (%)
throttle_pos = conn.query(obd.commands.THROTTLE_POS)
print("Throttle Position (%):", throttle_pos.value)
# Read coolant temperature (C)
coolant_temp = conn.query(obd.commands.COOLANT_TEMP)
print("Coolant Temperature (C):", coolant_temp.value)
# Close the OBD2 connection
conn.close()
```
### Example 2: Android App using the OBD2 Library for Android
This example demonstrates how to use the Mini elm327 Bluetooth OBD2 component with an Android app to read and display vehicle data, including vehicle speed, fuel level, and engine load.
Prerequisites:
Android Studio installed on your computer
OBD2 Library for Android installed in your project
Code:
```java
import android.bluetooth.BluetoothDevice;
import android.bluetooth.BluetoothSocket;
import android.os.Bundle;
import android.util.Log;
import io.github.obd2.obd2library.OBD2Command;
import io.github.obd2.obd2library.OBD2Manager;
import io.github.obd2.obd2library.OBD2Response;
public class OBD2Activity extends AppCompatActivity {
private OBD2Manager obd2Manager;
private BluetoothSocket socket;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.obd2_activity);
// Initialize the OBD2Manager
obd2Manager = new OBD2Manager(this);
// Connect to the Mini elm327 Bluetooth OBD2 device
BluetoothDevice device = BluetoothAdapter.getDefaultAdapter().getRemoteDevice("XX:XX:XX:XX:XX:XX"); // Replace with your device's MAC address
socket = device.createRfcommSocketToServiceRecord(UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"));
socket.connect();
// Read vehicle speed (km/h)
OBD2Command speedCmd = new OBD2Command("010D");
OBD2Response speedResponse = obd2Manager.sendCommand(socket, speedCmd);
Log.d("OBD2", "Vehicle Speed (km/h): " + speedResponse.getDecimalValue());
// Read fuel level (%)
OBD2Command fuelCmd = new OBD2Command("012F");
OBD2Response fuelResponse = obd2Manager.sendCommand(socket, fuelCmd);
Log.d("OBD2", "Fuel Level (%): " + fuelResponse.getDecimalValue());
// Read engine load (%)
OBD2Command loadCmd = new OBD2Command("0104");
OBD2Response loadResponse = obd2Manager.sendCommand(socket, loadCmd);
