Hi all,
I have just installed the ROS custom message add-on to the Robotics System Toolbox, and it seems to be broken - when I run rosgenmsg(folderpath), I get the error message:
"Undefined variable "hwconnectinstaller" or class "hwconnectinstaller.PackageInfo".
Error in robotics.ros.custommsg.internal.SupportPackage
Error in robotics.ros.custommsg.internal.setup.registerMessageCatalog (line 9) spPkg = robotics.ros.custommsg.internal.SupportPackage;
Error in rosgenmsg (line 33) robotics.ros.custommsg.internal.setup.registerMessageCatalog;"
I noticed another person with an identical problem commenting on the add-on 2 days ago. Does anyone know how to fix this please?

It's MATLAB 2017b, and that command unfortunately leads to "'hwconnectinstaller.PackageInfo' not found"...

Ok I am glad to announce that we fixed the issue in our product, and there is a new version for the addon 17.2.1 present.
On MATLAB from R2017b, >> roboticsAddons
Update your ROS Custom Message addon.
or can use MATLAB Home tab Add-ons > Manage Add-ons
