How to release Pc SDK Controller connection?

Developer Tools
1

Hi,

I’m using PCSDK 6.08 to connect to a controller and trigger a backup. Afterwards i make sure to log off from and dispose the controller. Still, it seems like a connection to the robot is in use, preventing other users to access the robot using e.g. RobotStudio.

Any thoughts on what I need to do to release the connection properly?

Thanks,
Henrik

PC SDK 6.08?! :slight_smile:

PC SDK is backwards compatible. I’d recommend you to try the latest version and see if the release of mastership + disposal of controller works correctly.

We have upgraded to PcSDK version 2024.3, but it still does not release the connection.
Closing the application seem to release the connection, but that’s not an option. Maybe if we break out the usage of PcSDK to a separate application that we trigger when needed. Doable but ugly and a lot of work.
Any other ideas?

It’s difficult to guess why that may be the case without knowing what code is running.

As far as I know there is no known bug that would be causing this behavior.

Found the problem.
We subscribed to the Controller’s ConnectionChanged event and forgot to unsubscribe.

Adding this line when cleaning up solved it:

controller.ConnectionChanged -= Controller_ConnectionChanged;
