The CAN controller goes into bus off mode when my application tries to send a CAN message. There is no activity on the CAN bus. Why?

[lpcware]

There are many causes of this and all relate to an issue between the CAN controller and the bus. For example no CAN transceiver, CAN transceiver disabled, broken connection between the CAN_L/H pins and the CAN controller.
