Four Connection Modes of Car Engine Code Reader

Fiberall specializes in producing car engine code reader for more than ten years. And we are able to provide car engine code readers with different connection methods. At present, we mainly provide four connection modes. Bluetooth, WiFi, USB cable and OBD cable.

As for Bluetooth car engine code reader, we offer Bluetooth 2.0, 4.0 and 5.0 for selection. Bluetooth 2.0 car engine code reader is for Android and windows systems. Its compatibility is limited. Bluetooth 4.0 and 5.0 car engine code readers are compatible with Android, IOS and Windows systems. Compare to Bluetooth 2.0, Bluetooth 4.0 and 5.0 have advantages in transmission distance, stability, security and compatibility.

WiFi car engine code reader can widely work with Android, IOS and windows devices. Its compatibility is relatively strong. But it requires environment with wireless network. It has faster transmission speed than Bluetooth. But the power consumption is generally larger than that of Bluetooth car engine code reader.

USB car engine code reader is for computer. It is popular with researchers. It is plug and play, and there is no need for too many settings. And there is no need for network support.

Car engine code reader with OBD cable is handheld type. They don't need to work with mobile phones or computers. They have their own display screen. User can see all information directly on the display. But they are a little bigger than Bluetooth and WiFi car engine code reader. It's not convenient to insert it on the car all the time. But only use it when necessary.

No matter which connection mode, their basic functions are roughly the same. There are also some models with some special additional functions. Customers can choose the most suitable car engine code reader according to different application situations.
