1.4 Remote Access

This guide explains how to remotely connect to your Bianbu ROS board from a PC using serial, SSH, or VNC. It includes connection methods, step-by-step instructions, and tool setup.

Serial Port Login​

Serial port access is useful for debugging, monitoring firmware flashing, or working without a network connection.

Hardware Connection​

Connect your PC to the MUSE Pi Pro board using a USB-to-TTL adapter. Attach the GND, TX, and RX pins as shown:

Login on Windows​

Using MobaXterm as an example:

  1. Connect the serial adapter and check Device Manager to find the COM port (e.g., COM5). Windows Serial Recognition

  2. Open MobaXterm → Sessions → New Session, then select Serial.

  3. In the configuration session:

    • Serial port: Select the detected COM port (e.g., COM5).
    • Speed: Set to 115200.
    • Click OK to open the terminal session.

    MobaXterm Serial Configuration

Login on Ubuntu​

  1. Check the available serial devices:

    ls -al /dev/ttyUSB*

  2. If the device is /dev/ttyUSB0, connect using the tool minicom:

    sudo minicom -D /dev/ttyUSB0

    If minicom is not installed, run:

    sudo apt install minicom

    For first-time setup on minicom, configure the baud rate:

    sudo minicom -s

    Set Serial port speed to 115200 and save the configuration.

💡 Tip: If login fails or you get a permission error, add your user to the dialout group:

sudo usermod -aG dialout $USER

SSH Login​

SSH is a common way to access the development board remotely over a local network.

Note: Ensure the board is connected to the network. For instructions, see Section Network Setup.

Connecting from Windows​

Using MobaXterm as recommended:

  1. Open MobaXterm → Sessions → New Session, then select SSH.

  2. Configure the SSH settings:

    • Remote host: Enter the board’s IP address (e.g., 192.168.1.100).
    • Specify username: Keep the default value, bianbu.
    • Port: Keep the default value, 22.

  3. Click OK, then enter the password to log in.

Connecting from Ubuntu​

Open a terminal and run:

ssh bianbu@<remote_ip>

Replace <remote_ip> with the board’s IP address. On first login, confirm the fingerprint by typing yes.

VNC Login​

VNC provides remote graphical desktop access and requires the VNC service to be running on the development board.

For instructions on enabling VNC, see 1.3 Enable VNC Service.

Connecting from Windows​

Using RealVNC Viewer as recommended:

  1. Launch VNC Viewer.
  2. Enter the address <remote_ip>:5900 (e.g., 192.168.1.100:5900) in the address bar.
  3. Press Enter to connect.

VNC Viewer Login

Connecting from Ubuntu​

Using Remmina as recommended:

  1. Install Remmina:

    sudo apt update
    sudo apt install remmina remmina-plugin-rdp remmina-plugin-vnc remmina-plugin-secret

  2. Launch Remmina:

    remmina

  3. Configure the connection:

    • Select VNC as the protocol.
    • Enter <remote_ip>:5900 (e.g., 192.168.1.100:5900) in the address bar.
    • Press Enter to connect.
