Briefly, the scenario is as follows: First, a serial Port is registered: "sdptool add --channel=2 SP" After that, dund is started and waits for incoming PPP requests: "dund -n --listen --channel=2 call dun" When an application - e.g. a web browswer is started on the phone, using a bluetooth access point configured via gnubox, the PPP link is fired up and the app works perfectly. Unfortunately, this works excactly once, because for some reason, the rfcomm device that was used for the PPP link disappears, which on the connection request makes dund complain "RFCOMM TTY creation failed. No such file or directory(2)" - I tried to (re-)create the device in /etc/ppp/ip-down but no avail... Here is the output of "hcidump -x" starting right before the application is closed on the phone: ---------- snip ----------- HCIDump - HCI packet analyzer ver 1.5 device: hci0 snap_len: 1028 filter: 0xffffffff > ACL data: handle 0x0029 flags 0x02 dlen 20 L2CAP(d): cid 0x41 len 16 [psm 0] 13 EF 19 7E FF 03 C0 21 05 03 00 04 85 72 7E 65 < ACL data: handle 0x0029 flags 0x02 dlen 25 L2CAP(d): cid 0x59 len 21 [psm 0] 11 EF 23 7E FF 7D 23 C0 21 7D 26 7D 23 7D 20 7D 24 48 57 7E BF > HCI Event: Number of Completed Packets(0x13) plen 5 01 29 00 01 00 < ACL data: handle 0x0029 flags 0x02 dlen 8 L2CAP(d): cid 0x59 len 4 [psm 0] 11 53 01 16 > HCI Event: Number of Completed Packets(0x13) plen 5 01 29 00 01 00 > ACL data: handle 0x0029 flags 0x02 dlen 8 L2CAP(d): cid 0x41 len 4 [psm 0] 11 73 01 3C > ACL data: handle 0x0029 flags 0x02 dlen 12 L2CAP(s): Disconn req: dcid 0x0041 scid 0x0059 < ACL data: handle 0x0029 flags 0x02 dlen 12 L2CAP(s): Disconn rsp: dcid 0x0041 scid 0x0059 > HCI Event: Number of Completed Packets(0x13) plen 5 01 29 00 01 00 ---------- snip ----------- And here are some notes on my configuration: - Gentoo Linux, Kernel 2.6.6 / patch-2.6.6-mh3.gz - Epox bt-dg02a USB BT dongle - bluez: kernel 2.3, libs 2.5, pan 1.1, sdp 1.5, utils 2.3-r1, hcidump 1.5 Any help and/or hints pushing me into the right direction will be greatly appreceated :-) Best Regards, Stephan Cremer. __________________________________________________________________ Zeigen Sie Emotionen mit der WEB.DE Bild-SMS!
