Hello, we had to change BlueROV 2 from RPi 5 back to RPi 4 and after the change we cannot see the SonarView in the Cockpit interface (neither in the dektop application or Cockpit Lite).

The iFrame says that the page is not ready yet and tries to load forever. The settings are shown in the figure.

Thank you for any help!

Hi @pavel.savin, welcome to the forum 🙂

Can you try turning on the “Use vehicle address as base URL” option and seeing if that helps?

Beyond that:

1. Which BlueOS version are you using?
2. Is that URL the same as the one you use to access SonarView outside of Cockpit?
  - If you aren’t already, can you try using the SonarView URL from the Available Services page in BlueOS?

Hello,

we are using 1.4.5., using checkbox you mentioned will make the iFrame working, but it displays only homepage of the blueOS in the RPi.

The URL is the same (as e. g. in the browser). I don’t have the ROV 2 now with me, but I can send the URL tomorrow, if it helps? : -)

Many thanks!

Pavel
