4.10 SignedFirmwareStatusNotification

The SignedFirmwareStatusNotification message is used by the charge point to notify the central system about the status of a firmware update process that has been signed. This helps the central system track the progress and outcome of the firmware installation.


API Syntax	Description	Input Params	Return Value
CreateFirmwareStatusNotificationRequestPacket	This function creates a JSON object representing a firmware status notification request packet.	void	static cJSON

Example:

    signedFirmwareStatusNotificationSendFrame = CreateOCPPFrame(OCPP_MESSAGE_CALL_CODE, GetOcppStatesBuffer(SIGNED_FIRMWARE_STATUS_NOTIFICATION), CreateFirmwareStatusNotificationRequestPacket());
    if (signedFirmwareStatusNotificationSendFrame == NULL)
    {
        OCPPLogMessage(LOG_ERROR, LOG_SENDING, "Failed to create OCPP frame\n");
        return SIGNED_FW_STATUS_ERR;
    }


API Syntax	Description	Input Params	Return Value
SetSignedFirmwareStatusNotificationStatus	This function sets the status of the signed firmware status notification. The status parameter, of type SIGNED_FW_STATUS_STATE_T, reflects the outcome of the signed firmware notification process.	SIGNED_FW_STATUS_STATE_T status	void

Example:

                    else if ((uint8_t)signedFirmWareState <= (uint8_t)SIGNED_FIRMWARE_SIGNATURE_VERIFIED)
                    {
                        LogDebug("APP_LOG", "Signed Firmware State is %s \n", GetChargerFwStatusInfoStr(signedFirmWareState));
                        SetSignedFirmwareStatusNotificationStatus(signedFirmWareState);
                        (void)SendSignedFirmwareStatusNotificationRequest();
                    }


API Syntax	Description	Input Params	Return Value
SendSignedFirmwareStatusNotificationRequest	This function is responsible for sending a signed firmware status notification request.	void	SIGNED_FW_ERR_STATE_T

Example:

                    else if ((uint8_t)signedFirmWareState <= (uint8_t)SIGNED_FIRMWARE_SIGNATURE_VERIFIED)
                    {
                        LogDebug("APP_LOG", "Signed Firmware State is %s \n", GetChargerFwStatusInfoStr(signedFirmWareState));
                        SetSignedFirmwareStatusNotificationStatus(signedFirmWareState);
                        (void)SendSignedFirmwareStatusNotificationRequest();
                    }
