For optimal performance, you must use a genuine or high-quality ELM327 Bluetooth adapter with firmware version 1.3 or higher.

❗ Important:

• Low-quality clones or outdated ELM327 modules may fail to communicate with your vehicle.
• Some cheap adapters do not properly support CAN BUS (HS-CAN) or fail to initialize at the correct baud rate.

🔧 Verify Your ELM327 Compatibility: 👉 Use the ELM327 Identifier App (available on Google Play) to confirm your adapter's firmware version and capabilities before using OPL DRC Reader.

📱 Compatibility

• Android 6.0 or higher
• Bluetooth 4.0+ (BLE compatible)
• Must support OBDII over CAN (ISO 15765-4)

💡 Tips for Best Results

1. Turn ignition to ON (without starting engine) before connecting.
2. Use a reliable ELM327 Bluetooth adapter (e.g., V1.5+, V1.6+, or V2.0+).
3. Ensure Bluetooth is paired and the connection is stable.
4. Some older or non-standard ECUs may not respond fully – expect limited data on some models.
