.. zephyr:code-sample:: ocpp
:name: OCPP charge point
:relevant-api: ocpp_api
Implement an OCPP charge point that connects to a Central System server and
simulates the meter readings.
Overview
********
Open Charge Point Protocol (OCPP) is an application protocol for communication
between Charge Points (Electric vehicle (EV) charging stations) and a central
management system, also known as a charging station network.
This ocpp sample application for Zephyr implements the OCPP library
and establishes a connection to an Central System server using the web socket
The source code for this sample application can be found at:
:zephyr_file:`samples/net/ocpp`.
Requirements
************
- Linux machine
- STM32 Discovery kit (32F769IDISCOVERY) or any network interface device
- SteVe Demo Server (<https://github.com/steve-community/steve/blob/master/README.md>)
- LAN for testing purposes (Ethernet)
Building and Running
********************
Build the ocpp sample application like this:
.. zephyr-app-commands::
:zephyr-app: samples/net/ocpp
:board: <board to use>
:goals: build
:compact:
The sample application is to built and tested on
.. code-block:: console
west build -b stm32f769i_disco
west flash
The output of sample is:
.. code-block:: console
*** Booting Zephyr OS build v3.6.0-rc1-37-g8c035d8f24cf ***
