| :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 |
