Hi Kevin,
I must admit that I'm not familiar with this environment, but I guess that if you want to see any real messages you should not put the CANbus in testmode. In this case nothing happens on the bus, only internally the Tx message is received by the Rx. Furtheron you have set the filter to ID 33, which means that only the message with ID 33 is received. To be active on the bus, you should also set the right bitrate. To see messages you don't need to send any message.
