Vgate vLinker MS ELM327 BT3.0 OBD2 Adapter – Android/iOS/iPhone

Introduction

Vgate vLinker MS BT3.0 is designed for those who want a powerful yet compact OBD2 adapter with exceptional compatibility. It builds on Vgate's proven ELM327 architecture but uses newer hardware (25K80) and communication via Bluetooth 3.0, which provides faster transfers and a more stable connection.

Unlike simpler adapters that only read basic DTCs, the vLinker MS also handles vehicles with multiple CAN networks – such as MS-CAN and HS-CAN in Ford cars or SW-CAN in GM vehicles. You can monitor live data, log measurements, check readiness for inspections, and save reports digitally.

Thanks to the built-in Battery Saver technology, the adapter can remain plugged into the OBD port without risking battery drain. It wakes itself up when you turn on the ignition and automatically goes into sleep mode after inactivity. This makes the vLinker MS ideal for daily use, both in passenger cars, light commercial vehicles, and heavy 24V vehicles.

Manual & installation guide

1️⃣ Preparations

1. Ensure the car has a 16-pin OBD2 port (under the dashboard).
2. Download your preferred OBD2 app according to your platform.
3. Enable Bluetooth on your device and keep it within 5m of the car.
4. Ensure good battery voltage (> 12 V).

2️⃣ Connect the adapter

1. Turn off the ignition before connecting.
2. Insert the vLinker MS into the OBD2 port.
3. Wait a few seconds until the LED lights blue (power on).
4. Turn on the ignition (ignition mode ON).

3️⃣ Bluetooth pairing

• On Android / Windows: Go to settings → Bluetooth → pair with “vLinker MS”.
• On iOS: Connect directly via the app's internal Bluetooth management (MFi).
• Code (if required): 1234 or 0000.
