Yes it certainly would matter doesn't it ? It basically tells that the overall UART speed is 115kbps... Generally BT chips on embedded systems nowadays are connected to HS UARTs which can support up-to 3.6/4Mbps. The device certainly has a different driver i.e /dev/s3c_serial1, So I am guessing it should support higher baud-rates. Also check out the MAX MTU size of the Obex. Try out obexftpd and obexftp command line tools on android, where you can play around with MTU for verification purposes... > Regards, > Ajith > > On Tue, Dec 28, 2010 at 1:00 PM, Ajith Kamath <sjce.aj...@gmail.com> wrote: >> >> Hi >> >> I have implemented FTP server V1.1 for Android over Bluez. >> But when I do the transfer to/fro , my speed is max 10.2~10.8KBps >> >> But then i checked Opp which is already implemented by google.
