### ros_canopen did not receive a response message

Hi, I trying to use ros_canopen to control a robot with canopen motors. I use indigo.

I run candump in a terminal. When I connect the motor to power ，candump receives:

can0 702 [1] 00 can0 082 [8] 30 81 00 00 00 40 00 00

So I suppose the hardware connection is correct.However when I run canopen_motor_node , it gave an error:

The branch of ros_canopen i use is indigo-devel,which i found out very different from indigo_release_candidate.Which one is more recommended?

I've tried to read the code where produces the "Did not receive a response message" but could to find out how to solve this problem.
