Now that you have your Pi up and running you want to remotely access it (in Headless mode) through VNC viewer, which you installed on your laptop or desktop (see VNC Installation Instructions ). Activate VNC on Raspberry Pi The easiest way is to click the Raspberry icon on the taskbar, choose preferenes/Raspberry Pi Configuration/Interfaces and toggle VNC to on (figure \(\PageIndex{1}\) Obtain Pi IP address Your desktop VNC viewer connects to the Pi over the internet through the Raspberry Pi's IP (Internet Protocol) address. This is a string of digits containing 4 sets of numbers separated by decimal points xxx.xx.xx.xx, and is like the web address for the Pi. These are assigned by your Internet Service Provider and may be static or dynamic. If it is static, it will never change, and you only have to do this once. If it is dynamic you will have to get the IP address every time it changes. Do deal with this we will set up a program that emails your IP address upon bootup. Note If you are at UALR you need to connect your Raspberry Pi to the IOT WiFi network, and this requires you to register it with IT Services (see instructions here). You can get your IP address by going to IT services and looking up your device Set up Desktop VNC Connection You can actually run multiple VNC connections at the same time. First you need to set up a connection, which you can do by right-clicking in a blank area of the viewer and choosing "new connection", or choosing file/new connection. This opens the panel if figure \(\PageIndex{3}\), you type in your IP address and give your connection a name Note If you have an existing VNC connection and it does not work because the Raspberry Pi IP address changed, you can right click on it, and choose properties. That will open the panel in the left image of figure 3, and allow you to update the IP address.

It is very important that you structure your directories (folders) on both your PC and the Pi so that you can keep your work organized. Therefore you should choose the destination folder with some fore thoughtl. PC2Pi To transfer from your personal computer (PC) to the the Pi you can use the collapsible menu at the top center of the Raspberry Pi desktop. You will need to navigate to the folder containing the file you want to upload to the Pi, and you can then place it on the Pi's desktop. Go to the collapsible menu and choose the "Transfer Files" options Choose Send "files.." Navigate to the folder on your PC having the file you want to upload and click on it Choose "Open" The file will now be uploaded to your Raspberry Pi desktop. Pi2PC THe following steps allow you to transfer a file from your Raspberry Pi to your personal compter or laptop. You should set up a destination folder in your PC before you start sending files. Right Click on VNC icon Choose the "File Transfer" option Choose "Send Files" Navigate to the directory of the file you want to send Click OK Choose the destination directory on your PC Choose Send Files. VNC Issues Sometimes you lose the VNC Icon and can not transfer files. This is because you are running WayVNC server on the pi and not RealVNC Server. To fix this you must operate on Desktop mode as you will be disconnecting VNC. start by typing: sudo raspi-config this opens the configuration tool and choose: 6 Advanced Options A6 Wayland W1 X11 finish and reboot Once you reboot you need to restart VNC Viewer, which you can do from the configuration tool or from preferences. In the case of the configurationt tool choose 3. Interface Options I2 VNC Yes finish
