OBD2 scanner tools communication channels
OBD2 scanner communication channels such as USB, RS232, Bluetooth and WiFi. But what scanner is the one with the right of communication you need?
Now, I will present some OBDII scanners with various communications to you.
USB OBD2 diagnostic scanners lets you use your PC and a hardware interface to get the information from the computer of your car, instead of displaying the test result directly on the screen of the interface (such as self-code scanners.) These PC-based tools are usually professional and works with one or more models of cars that can read error codes, clear fault codes, reading live data, etc.
These OBD2 scanners, for example, are Honda HDS, star of Mercedes Benz C3, C4 star Diagnostic Interface Nissan Consult, sbb key programmer, Motorola MC68HC05M programmer, developer of Motorola 705, Motorola MC68HC08 Programmer 908 and more. As you can see, some of them are professional diagnostic tools, some are car key programmer, and programmer ECU. No matter what you work as they work through the serial port.
There is a part of the OBD2 diagnostic tools communicate via Bluetooth. VAS5054 Take for example, vas 5054a is a universal diagnostic interface for the vehicles of the Volkswagen Group and all OBD vehicle systems from other manufacturers. The integrated Bluetooth interface connects the vehicle with a laptop, desktop PC or test system. No cables are needed for vehicle diagnostics using the VAS 5054A. The scope of the Bluetooth wireless connection is 5 to 10 meters, depending on the environment and the type of Bluetooth adapter used on the PC side. The Serial Port Profile (SPP) is used to transfer data via Bluetooth. Different Bluetooth security levels are supported.
In addition, there are some Bluetooth OBD scanners, such as elm327 bluetooth scanner tools, Nissan Consult 3, Launch X431 Launch X431 Diagun tool.
Such as USB OBD2 EOBD WIFI327 WIFI scan tool; WIFI327 OBD2 scanner is the latest PC-based scan tool. It supports all OBD-II protocols and is dispatched with a number of compatible programs. The output protocol (connection to laptop) is a USB cable, add the new form of communication: WiFi, Wi-Fi range is over 20 meters and running smoothly compared to Bluetooth communication.
