Send and receive raw CAN frames using BSD sockets API.
Overview
********
The socket CAN sample is a server/client application that sends and receives
raw CAN frames using BSD socket API.
The application consists of these functions:
* Setup function which creates a CAN socket, binds it to a CAN network
interface, and then installs a CAN filter to the socket so that the
application can receive CAN frames.
* Receive function which starts to listen the CAN socket and prints
information about the CAN frames.
* Send function which starts to send raw CAN frames to the bus.
The source code for this sample application can be found at:
:zephyr_file:`samples/net/sockets/can`.
Requirements
************
You need a CANBUS enabled board like :ref:`nucleo_l432kc_board` or
:ref:`stm32f072b_disco_board`.
Building and Running
