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
