Error in CAN connection while operation

[Robotawi]

Hello
I have been using BarrettHand for some time with your ROS package.
I encounter the following error in the window in which I roslaunch bhand_controller file.
The error keeps being repeated, and the hand doesn't respond any more.

Would you please help me to find the problem?
Thank you

I have been having a similar issue, however only when I run the bhand_controller on kinetic. Is there any way we can get support for kinetic or using the peak driver v8.5.1?

[RomanRobotnik]

Hi David,
I'd like to upgrade it for the new peak driver, but for now I don't have time to do it, sorry.

[MohamadHalwani]

did you do so ??
Thanks :)
