ELM329 vLinker is a next-generation diagnostic adapter created as a replacement for the outdated ELM327 version. Despite its fundamentally updated architecture, the adapter maintains full backward compatibility with all protocols and software designed for ELM327. This makes it a universal solution for both professionals and car enthusiasts.
A key feature of the ELM329 is its specialization in tasks requiring the transmission of large volumes of data, such as advanced diagnostics, coding, and programming of Electronic Control Units (ECUs) in modern vehicles.
Compatibility with Mobile and Desktop Devices
The adapter works with all popular operating systems:
- Android (smartphones and tablets)
- iOS (iPhone, iPad)
- Windows (laptops and PCs)
This is a fundamental difference from classic Bluetooth 1.x, 2.x, 3.x adapters, which cannot be used with Apple devices due to iOS hardware restrictions. While Wi-Fi-based adapters disable mobile internet on iPhone/iPad, the vLinker ELM329 Bluetooth 4.0 lacks this drawback, allowing you to maintain a network connection during diagnostics.

Detailed Technical Specifications
In addition to high speed and compatibility, the adapter features several advanced technical solutions:
- Intelligent Power Management: A built-in CAN monitor automatically puts the adapter into sleep mode when the ignition is turned off. This allows it to be left in the OBD-II port permanently without the risk of draining the battery. Operating current is only 51 mA, standby current is 3 mA.
- Increased Buffer and Speed: USART data buffer increased to 2 KB, and serial port speed up to 230.4 Kbps, ensuring stable communication without packet loss.
- Wide Protocol Support: Full OBD-II and extended protocol support, including those specific to American vehicles and heavy machinery (J1939).
- Multiple Wake-up Protocols: Up to 3 different methods to wake the adapter from sleep mode, increasing connection reliability.
- Long-term Support: The manufacturer regularly releases firmware updates via the VgateFwUpdater app, optimizing performance with new car models.
