Jukka Rissanen c0fcd8c9b5 samples: net: sockets: can: Fix the test termination criteria If enabling CONFIG_POSIX_API, we get three file descriptors open before any socket descriptors. The sample exit criteria checks socket 0 and 1 which is no longer a valid one, so change the check to be either 0 or 3, and 1 or 4 so that the test can be run in both when POSIX API is enabled or disabled. Also disable color printing for the test run so that it is easier to read the output log. Signed-off-by: Jukka Rissanen <jukka.rissanen@nordicsemi.no>		2024-03-27 13:40:13 -05:00

.. zephyr:code-sample:: socket-can
   :name: SocketCAN
   :relevant-api: bsd_sockets socket_can

   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
********************

Build the socket CAN sample application like this:

.. zephyr-app-commands::
   :zephyr-app: samples/net/sockets/can
   :board: <board to use>
   :conf: <config file to use>
   :goals: build
   :compact:

Example building for the nucleo_l432kc:

.. zephyr-app-commands::
   :zephyr-app: samples/net/sockets/can
   :host-os: unix
   :board: nucleo_l432kc
   :goals: run
   :compact:
