Network Topology and Raspberry Pi Configuration

This page outlines how to reconfigure the raspberry Pi to use an external network instead of its own.

A better network connection topology is having all the machines working together connected over the same network. The Clover's Pi originally is setup to provide its own network through the access point mode therefore it must be reconfigured to connect to the wifi router and communicate with the other machines such as the motion capture system computer. This reconfiguration process can be found on the Clover website where the steps are repeated here:

  1. Disable the dnsmasq service. 

    sudo systemctl stop dnsmasq
sudo systemctl disable dnsmasq

  2. Enable DHCP client on the wireless interface to obtain IP address. In order to do this, remove the following lines from the etc/dhcpcd.conf file: 

    interface wlan0
static ip_address=192.168.11.1/24

  3. Configure wpa_supplicant to connect to an existing access point. Change your /etc/wpa_supplicant/wpa_supplicant.conf to contain the following: 

    ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
 update_config=1
 country=GB

 network={
     ssid="SSID"
     psk="password"
 }

  4. where SSID is the name of the network, and password is its password.

  5. Restart the dhcpcd service.

    sudo systemctl restart dhcpcd

To configure the wpa_supplicant.conf file use sudo for permission. Also, the permanently set static IP address of the Pi has been turned off so in order to ssh connect to the Pi. You need the one assigned when it is connected to the wifi router. This can be found by connecting the Pi to a monitor, and using a keyboard login with:

  • Username: pi

  • Password: raspberry

Then type:

ip a

You'll get a screen like the following figure with the highlighted IP.
