Hi All, I am working on the eclair code base. And I just started enabling BlueZ and started working on it. The basic profiles seems to be working fine. But When I play media on my headset there is a time delay oocured when playing the media on headset and hence after 2 seconds of play it stops for 2 seconds and plays again. During this process I saw error message "a2dp_write failed err: -110".

As of now I am using the Baud rate of 115200 should I increase the baud rate. If yes please let me know how can I do that since hciconfig hci0 up is not working with baud rate more than 115200. waiting for ur reply guys Thnaks in Advance! -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting
