[This is preliminary documentation and subject to change.]
The minimum recommended PDU maximum size (maximum receive unit), has value 255.
See OBEX13.pdf section 3.3.1.4.
Even though the specification says that “This value is the minimum acceptable value for the OBEX Maximum Packet Length parameter exchanged in the CONNECT Operation.” we do not enforce this strictly as we know that some devices do use a smaller buffer size, we do write a Trace warning.
