BUSMASTER Setup

BUSMASTER is an open-source PC software for designing, monitoring, analyzing, and simulating CAN networks. It is highly regarded by engineers for its rich feature set, including node simulation and message logging.

The WiCAN Pro supports BUSMASTER natively over Wi-Fi by utilizing the slcan (SocketCAN) protocol and a virtual serial communication (VSCOM) bridge.

Phase 1: WiCAN Pro Configuration

Before opening BUSMASTER, you must configure the WiCAN Pro to output the correct protocol.

  1. Access the WiCAN Pro Web UI.
  2. Navigate to Settings > CAN.
  3. Configure the following fields:
    • CAN Bitrate: Set this to match your vehicle's bus speed (e.g., 500K).
    • CAN Mode: Choose Normal if you want to interact and simulate nodes, or Silent if you only want to passively log and monitor traffic.
    • Port Type: Select TCP.
    • TCP/UDP Port: Note this number (typically 3333 by default).
    • Protocol: Select slcan. (Note: Do not use the ELM327 protocol, as it will not work with BUSMASTER)
  4. Click Submit Changes and allow the WiCAN Pro to reboot.

Phase 2: Connecting to the Network

  1. Ensure your Windows PC is connected to the WiCAN Pro's network.
    • If in AP Mode, connect your PC directly to the WiCAN's Wi-Fi hotspot. The IP will usually be 192.168.0.10 (for WiCAN Pro).
    • If in Station Mode, ensure both your PC and the WiCAN are on the same local network. Check the WiCAN's Status tab for its assigned IP address.

Phase 3: BUSMASTER Configuration

  1. Download and install BUSMASTER on your Windows PC.
  2. Open BUSMASTER.
  3. In the top menu, go to CAN > Driver Selection.
  4. Select the VSCOM (Virtual Serial COM) or SocketCAN/Lawicel hardware driver.
  5. Go to CAN > Channel Configuration or click the Connect button.
  6. When prompted for connection details, enter the WiCAN's IP address and Port (e.g., 192.168.0.10:3333).
  7. Set the baud rate to match what you configured in the WiCAN Web UI (e.g., 500 kbps).
  8. Click Connect or OK.

You should now see the green connection indicator in BUSMASTER, and raw CAN traffic will begin populating the message window!

!WARNINGFailed to start the hardware: If you immediately receive a "Failed to start the hardware" error in BUSMASTER, it typically means your IP/Port is incorrect, or the WiCAN Pro is not set to the slcan protocol. Double-check your Web UI settings and ensure your PC's firewall isn't blocking outbound TCP connections.
