Bluetooth OBD2 adapters have revolutionized vehicle diagnostics, offering an accessible and user-friendly way to monitor your car’s health and performance. When paired with the Torque app on your Android device, these adapters become powerful tools, displaying real-time data and providing insights into your vehicle’s operation. This guide will explore how to effectively use Bluetooth OBD2 adapters with the Torque app, particularly in conjunction with systems like the Orion Battery Management System (BMS).
Understanding Bluetooth OBD2 Adapters and Torque App
OBD2 (On-Board Diagnostics II) is a standardized system that allows you to access vehicle data. Bluetooth OBD2 adapters plug into your car’s OBD2 port, typically located under the dashboard, and wirelessly transmit data to devices like smartphones and tablets.
The Torque app is a popular Android application that leverages this OBD2 data. It transforms raw data into visual gauges and readouts, displaying parameters such as engine temperature, speed, RPM, and much more. Its customizable interface and extensive features make it a favorite among car enthusiasts and professionals alike.
For those working with advanced systems like the Orion BMS, Torque becomes even more valuable. The Orion BMS, designed for electric vehicle battery management, outputs data via the OBD2 protocol. By connecting a Bluetooth OBD2 adapter and using Torque, you can monitor critical battery parameters alongside standard vehicle data.
Key Features of Torque App
- Real-time Data Display: Monitor a wide array of vehicle parameters in real-time.
- Customizable Gauges: Personalize your dashboard with various gauge styles and layouts.
- Fault Code Reading and Clearing: Diagnose and clear diagnostic trouble codes (DTCs).
- Data Logging: Record data for in-depth analysis and performance tracking.
- Compatibility: Works with most OBD2 compliant vehicles and systems like Orion BMS.
Setting Up Your Bluetooth OBD2 Adapter with Orion BMS
To use Torque with an Orion BMS via a Bluetooth OBD2 adapter, you’ll need to establish a physical connection and configure the software. Here’s a step-by-step guide:
Wiring the Bluetooth OBD2 Adapter
The Bluetooth OBD2 adapter needs to be correctly wired to the Orion BMS CAN bus network. CAN (Controller Area Network) bus is a communication standard used in vehicles. Here’s the essential wiring configuration:
| OBD2 Pin # | Connect to |
|---|---|
| 6 | Orion BMS CAN High |
| 14 | Orion BMS CAN Low |
| 4 & 5 | 12V Ground |
| 16 | +12V (Power for Adapter) |
It’s crucial to ensure these connections are accurate. Incorrect wiring can lead to communication issues or even damage to your devices. Refer to the full OBD2 connector pinout available on the OBD2 Wikipedia page for more detailed information.

CAN Bus Configuration Notes
- Termination Resistors: CAN networks require 120-ohm termination resistors at each end. Ensure your CAN bus setup includes these. Consult the Orion BMS wiring manual (https://www.orionbms.com/manuals/wiring) for detailed CAN bus wiring guidelines.
- Baud Rate: The Orion BMS CAN bus interface must be set to either 250 Kbps or 500 Kbps to comply with OBD2 standards. This setting can be adjusted in the “Communications Settings” within the BMS Profile section of the Orion BMS utility software.
- ECU ID: In vehicles with multiple ECUs (Engine Control Units), each must have a unique ID. If necessary, the OBD2 ECU ID of the Orion BMS can be changed in the “Communications Settings” to avoid conflicts.
Configuring the Torque App to Read Orion BMS Data
Once the hardware is connected, you need to configure the Torque app to recognize and display data from the Orion BMS. There are two primary methods for adding Orion BMS parameters (PIDs – Parameter IDs) to Torque:
Method 1: Manual PID Entry (Recommended for Beginners)
This method involves manually inputting each PID into the Torque app.
- Download Orion BMS Torque PIDs PDF: Obtain the PDF file containing the list of Orion BMS Torque Extended PIDs: Orion BMS Torque Extended PIDs (PDF).
- Access Torque Settings: Open the Torque app and navigate to “Settings”. This is usually accessed via the menu button on your Android device.
- Manage Extra PIDs/Sensors: Scroll down and select “Manage extra PIDs/Sensors”.
- Add Custom PID: Press the menu button again and choose “Add custom PID”, then confirm by pressing “OK”.
- Enter PID Information: For each PID you want to monitor, fill in the details from the downloaded PDF.
- Repeat: Repeat steps 4 and 5 for all desired PIDs.
- Return to Main Screen: Use the back button to return to the Torque main screen.
- Realtime Information: Tap “Realtime Information” to access the gauges display.
- Add Gauges: Long press on the screen and select “Add gauge”. The manually added PIDs should now be available to select for your gauges.
Method 2: Automatic PID Entry (For Advanced Users)
For a faster setup, you can import a CSV file containing all the Orion BMS PIDs.
- Download Orion BMS Torque PIDs CSV: Download the CSV file to your Android device: Orion BMS Torque Extended PIDs (CSV).
- Install File Manager: If you don’t have one, install a file manager app like “Astro File Manager”.
- Navigate to Torque Folder: Open the file manager and locate the Torque app’s home folder, typically found at ‘/mnt/sdcard/.torque’ or ‘/.torque’.
- Copy CSV File: Copy the downloaded “orionbms_pids.csv” file into the ‘extendedpids’ folder within the Torque directory.
- Restart Torque: Close and re-open the Torque app.
- Manage Extra PIDs/Sensors: Go to “Settings” and then “Manage extra PIDs/Sensors”.
- Add Predefined Set: Press the menu button and select “Add predefined set”.
- Select Orion BMS PIDs: Choose “orionbms_pids” to import the entire set of predefined PIDs.
- Return to Gauges: Return to the main screen and then to “Realtime Information”.
- Add Gauges: Long press to add gauges, and the imported PIDs will be available for selection.
By following these steps, you can effectively use Bluetooth OBD2 adapters and the Torque app to monitor your vehicle and, specifically, gain valuable insights into your Orion BMS performance. This combination provides a powerful and customizable diagnostic and monitoring solution.
