Setting up WDS bridging

The router connected to the base station will be used as the master router. The other router is the client router.
WDS briding should be enabled on the client router so that it is connected to the SSID of the master router.
DHCP should be disabled on the client router.
Assign static IP to Jetson and basestation.
Testing can be done to see if the bi-directional connection is established between the jetson and the base station:
- ping base_station_ip.
- netcat:
  - Listen on one computer: nc -l port_number.
  - On the other computer: nc -p port_number ip_of_the_listened_computer.
  - Characters typed in one computer should be echoed on the other computer.

Configuring environment variables and hosts

Setting up ROS_IP environment variable on both Jetson and basestation: export ROS_IP=their_respective_ip.
roscore will be run on Jetson, modify /etc/hosts on the basestation to map the address of Jetson to its hostname.
Setting up ROS_MASTER_URI environment variable on the basestation: export ROS_MASTER_URI="http://jetson_host_name:roscore_port"
Testing the ros connection:
- Run roscore on Jetson.
- Publish topic on either computer then try to echo the same topic on the other computer.
