How to capture sent message

[blairfancy]

Hi any way to capture sent message for file logging purpose? With can library it is easy has can message are clear but in canopen has we manipulate only object we do not have access to real can message sent. What i do in can is to put all sent and received message to a queue object for further traitement. Can we do the same in canopen?

hope my question is clear enough.

Which CAN interface are you using? Some of them support receive_own_messages and in combination with a listener you could be able to log all messages.

I use Ixxat USB can interface. 'receive_own_messages = True' seems usable on this interface.

Then you should be able to add receive_own_messages=True to network.connect(), then add a callback function to network.listeners. Let me know if you need more guidance.
