6.1 Programming config.json

The config.json file in the OCTT server is a critical configuration file that defines the operational parameters and settings for the server.

You need to provide the URL and the port number required on the target/client side to establish a WebSocket connection with the OCTT server:

  1. If required, edit the config.json file located in the demo_ocpp_v16_harmony/apps/firmware/src/sdcard folder and perform the following updates:
    • Set the SecurityProfile variable to 0 (non-secured profile).
    • Set the WS_URL variable using the URL and port number displayed on the OCA interface as follows:

      ???

    • The WS URL can be found on the OCA interface:

      ???
      Note: The WS URL format is: URL + Port.
  2. Copy the config.json file to the root of your SD card.
