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)

Using MobaXterm as an example:

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

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.

   

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 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 (using MobaXterm)

Using MobaXterm as recommended:

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

2. Configure SSH Settings:

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

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 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
