SocketCAN buffer fills up

Hey!

 

I recently got a CAN-bus up and running on a Tinkerboard running Armbian, but I've run into another problem here:

The CAN-bus buffer fills up.

 

After sending a few messages I get an error saying "No buffer space available".

 

I've noticed that some other people are solving this by increasing the buffer size, but that seems like a weird solution to me.

And it wouldn't really help me much. I need to empty this buffer when I read from it, or manually (without restarting the CAN-bus).

 

Any ideas on how to do that?

 

Thanks :)
