When I sent data to h4 interface, h4 make frame and btsco sent that frame to the SCO channel. The frame size from h4 interface is varied periodically and somtimes larger than MTU size so SCO channel drop several frames. Of course I changed the MTU size using "hciconfig scomtu" command but it is not effective at all. Now, I tested the problem using samsung module based on CSR bluecore chipset. However, there is no problem if I use SCO over USB because the frame size from USB is always same & smaller than MTU. -- Youngwoo Park M.S. Student CORE(COmputer engineering REsearch) Lab Dept.
