Hello all,
I am programming for transferring data between my Linux box and mobile phone. But while transferring large files it takes quiet a few time.
I want to achieve maximum data transfer rates without affecting reliability of system. I am using "object push service" for this. And tried changing default MTU size in /usr/include/openobex/obex_const.h
But got same results.
Can anyone tell me how can i increase MTU size? Or is there any limitation on it? (I think Max. MTU size can be 64k).
Any help or suggestions are appreciated.
