2.1.5 RegisterOCPPCallback(OCPPCallBackFn)
The RegisterOCPPCallback(OCPPCallBackFn) function allows you to register a callback function (OCPPCallBackFn) that will be invoked whenever the OCPP server sends a response. This callback function enables the application to handle incoming messages from the server. By examining the response code or message type within the callback, the application can determine if the request was successful or if there was an error, and decide on the appropriate next steps.
