Hi @en_morty,
Thanks for reporting the issue, I was able to replicate it and we are going to work on a solution as soon as possible.
To follow the status: bug: Failing to create bridges when configuring as a client · Issue #1113 · bluerobotics/BlueOS · GitHub
Now to help you using BlueOS:
On the first image you are configuring Companion to connect over a UDP Server running on the surface computer (192.168.2.1) with an UDP Client, on the BlueOS you are configuring a UDP Server when using the local ROV IP (192.168.2.2 / 0.0.0.0), for that to work, your matlab code will need to be a UDP Client.
That’s a temporary solution while we are fixing the issue, be sure to send something from the matlab code to register your UDP client.
