Hi, Pavel
I am using a USB-CAN cable to check the libcanard worked fine or not.But after I open the UAVCAN GUI Tool, I got a fatal error as follow:

What should I do to fix the error? In my main loop, I just call the sendCanard(); receiveCanard(); spinCanard(); and I can see the nodestatus message per second through a standard CAN GUI Tool.

I am sorry the screen shot is in Chinese,the message is a external frame & data frame,the frame ID is 18015564 in hex style.
I'm confused that why I can not connect to the UAVCAN node through the UAVCAN GUI TOOL?
Thanks.
