[This is preliminary documentation and subject to change.]
The default maximum PDU size (maximum receive unit), has value 255.
See OBEX13.pdf section 3.3.1.3.
At Connect time the peers each send their “maximum OBEX packet length”, and each will thereafter use the value received as their maximum send size.
To restrict the maximum size packet we will *send* use the Mtu property.
