Setting up test computer

Hi Alan,

For now, it’s not possible to install companion manually.

Manual Companion RPi Install?

We would like to use the Simulink/ROS stack available via MathWorks for some controls experiments with our new BlueROV2, and from the Simulink side this is done by using Mathworks’ pre-canned image in the RPi side (some Raspbian version and a ROS Indigo build that works with it). I’d like this to run on the companion RPi, as we are moving towards “cutting the tether”, but I see the standard way of configuring the companion RPi is also via an image. Is there 1) a reasonably straightforward way …

It doesn’t start automatically on reboot.

For that, you’ll need to make .companion.rc to start with the system, this will call all necessary companion components.

Also can I change the IP address on gGroundControl from 192.168.2.1 is the same as my router and it is a pain fiddling with my network each time

You can use set_default_client_ip.sh (E.g: ./set_default_client_ip.sh 192.168.2.2) to set the raspberry IP address for ethernet connection. If you are running a Linux in your surface computer, you can use nmap to find the ip while scanning port 22 (E.g: nmap 192.168.0.1-255 -p 22).

Can you use the companion image ?
