Tilman Glötzner (GERMANY)
I would like to write a little program that sents a can message, while listing at the same time for a response from the CAN nodes connected to the BF537's CAN interface.
I tried to do this on the command line by 'cat /dev/can0 & ' and then using can_send. Unfortunatelly, this locks the can0 device, so that I cannot sent the can message. The demo programs in user/can4linux/ do not really offer a clue.

I think you can write a program, open the CAN device (e.g, /dev/can0), then do read() and write() on it. Please refer to can4linux/transmit2.c.
