Bluetooth to CAN Dongle

Wireless Vehicle Diagnostics & ECU Interaction Platform

The Bluetooth to CAN Dongle from Infiquity Auto Technologies is a compact, plug-and-play diagnostic and control device designed to provide wireless access to vehicle ECU data. Built on CAN, UDS (ISO 14229), BLE 5.0, and OBD standards, the dongle enables real-time diagnostics, ECU programming, and actuator control using a mobile application.

Core Capabilities

  • 1. CAN-UDS Based Diagnostics

    The dongle communicates directly with vehicle ECUs over the CAN bus using Unified Diagnostic Services (UDS). This enables standardized access to ECU data, fault codes, routines, and control services, ensuring compatibility across vehicle platforms.

  • 2. Real-Time Vehicle Data & Fault Diagnostics

    • The dongle provides:

      • Live ECU data streaming from vehicle sub-systems and sensors

      • Standardized Diagnostic Trouble Codes (DTCs) for rapid fault identification

      • Quick insight into vehicle health, enabling faster troubleshooting and reduced service time

      All diagnostics are performed in real time over BLE, making vehicle analysis efficient and user-friendly.

  • 3. Bluetooth Low Energy (BLE 5.0) Interface

    Using BLE 5.0, the dongle wirelessly transmits ECU data to a mobile application, eliminating the need for wired diagnostic tools. This provides a seamless user experience for technicians, service personnel, and vehicle owners.

  • 4. Data Logging & Traceability

    Onboard SD Card Logging

    The device includes an onboard SD card slot that allows:

    • Storage of complete client-server communication logs

    • Text-based logging of diagnostic sessions and ECU interactions

    This is especially useful for debugging, field trials, validation, and post-analysis.

Power & Installation Simplicity

  • ECU-Powered Operation

    The dongle does not require any external power source. It draws power directly from the vehicle ECU via the OBD interface, simplifying installation and reducing hardware complexity.

    OBD-Based Plug-and-Play Connectivity

    The device connects to the vehicle using a standard OBD adapter, enabling quick deployment without any vehicle modification.

Mobile Application Integration Vehicle ECU data is accessed through an Android mobile application over BLE 5.0, providing: Wireless diagnostics Live data visualization Fault code monitoring and clearing ECU interaction from a handheld device This makes the solution ideal for service technicians, field engineers, and fleet operators.

ECU Programming & Control

 

ECU Programming via SD Card

The dongle supports ECU programming using CAN-UDS, with firmware or data loaded through the SD card. This enables:

  • Software updates

  • Calibration and configuration changes
