You would like to know whether it is possible to send/store 255 chars in any of the standard data types.
There is no provision for any standard data type to hold more than 255 Chars as per standard design of the product. You can in SDK, if this can be achieved.
For Example, Odata service datatype Binary has capacity to store more then 255 char. This is specific for AttachmentFolder and the Binary data type can be used only for attachments, media files or any file related queries.
This data type cannot be pushed with other standard fields because the underlying BO have the restrictions.
