(two PCs, each with single adapter; client sends 48 bytes packet to server every 1 second) After establishing a L2CAP between two adapters, I tried to set the "automatic flush timeout" on the client adapter with timeout to be 2. The hci_send_req is successful, but after 7 to 8 seconds, the server adapter stops to receive any data while client socket is still sending data. If I set it timeout to 4, then everything is fine. What I am imagining is "some data on client adapter may be flushed, but the later packet should continue to be sent to server adapter". Am I doing something wrong? // build a command packet to send to the bluetooth microcontroller cmd_param.handle = connection_handle; cmd_param.flush_timeout = htobs(timeout); rq.ogf = OGF_HOST_CTL; rq.ocf = 0x28; rq.cparam = &cmd_param; rq.clen = sizeof(cmd_param); rq.rparam = &cmd_response; rq.rlen = sizeof(cmd_response); rq.event = EVT_CMD_COMPLETE; // send the command and wait for the response err = hci_send_req( dd, &rq, 0 ); if( err ) goto cleanup; ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Bluez-devel mailing list Bluez-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bluez-devel
