ROSbridge with the RaspberryPi image

Hi Everyone!

Total newbie here so thank you for the awesome forum and support.

I’m using the Image on a RasberryPi 3 and am trying to install the ROSbridge package so that i can open a websocket and control the bot that way.

I’m having issues launching what I thought was the server as $roscore returns that I’m already running roscore/master (ROS_MASTER_URI) on a local port (11311).

I have put ROSbridge into catkin_ws/src/ and rebuilt the catkin workspace - but am unsure how to set up the next step as the tutorials I’m following say to run a roscore … but I’m already running the ubiquity one

Is there any advice?
