Data Transfer

Description.

Data Transfer is used to transmit custom messages to and from the CSMS over OCPP.

DataTransferRequest

Topic: cs/josev or josev/cs. Used to send a custom DataTransfer message.
type	object
properties
id	type	string
	format	uuid
name	const	data_transfer
type	const	request
data	type	object
	properties
	vendor_id	type	string
	message_id	type	string
	data

Example:

{
    "id": "57828133-8cfe-477d-b829-0b60aff90c2a",
    "name": "data_transfer",
    "type": "request",
    "data": {"vendor_id": "vendor-id",
             "message_id": "message-id", # OPTIONAL
             "data": "data" # OPTIONAL
            }
}

data field can be any format

Data can be free form and the format should be agreed with the CSMS. The CSMS and Charging Station should be recognising the specific vendor and message ID and processing the data field accordingly. Josev itself will not do any processing of this message, it merely passes it between the CS and the CSMS.
