send
(msg, timeout=None)[source]¶ Transmit a message to the CAN bus.
Override this method to enable the transmit path.
Parameters: - msg (can.Message) – A message object.
- timeout (float) – If > 0, wait up to this many seconds for message to be ACK:ed or for transmit queue to be ready depending on driver implementation. If timeout is exceeded, an exception will be raised. Might not be supported by all interfaces.
