Network
The network configuration is not handled via the NetworkManager. Instead we installed a preconfigured static configuration. The default WiFi configuration is:
| SSID | ROS |
| PASSWORD | elfmeter |
| SSID | ROS |
| IP | 192.168.43.XXX |
| Gateway | 192.168.43.1 |
| DNS | 8.8.8.8 |
The default ethernet configuration is:
| IP | 192.168.43.199 |
| Gateway | 192.168.43.1 |
| DNS | 8.8.8.8 |
The configuration is applied through netplan and can be changed in /etc/netplan/01-netconfig.yaml and /etc/netplan/02-wireless.yaml. If you need to change the WiFi connection, either plug a monitor and keyboard to the computer or connect through ethernet.
When changing the car’s IP address the environment variable ROS_HOSTNAME must be changed as well. By default these environment variables are configured in ~/ros-config.sh.
