How to connect two channels simultaneously?

[wangxj2014]

We use "CanOpenCommunicationManager._canopen_network_0.connect(bustype="canalystii", channel=[0], bitrate=500000)" to connect canalystii device. How to connect two channels simultaneously?

What do you expect to happen when "connected to two channels simultaneously"?

A CANopen network lives on one CAN bus (channel). Many properties of the protocol depend on that fact, in essence that every node on the bus receives the same messages and any message sent reaches all of the other nodes. That is not guaranteed if you try to work with two independent CAN networks at the same time.

If what you want is to bridge between two buses, as if they were one bus, maybe the new can.bridge utility from python-can can help you.
