I'm trying to connect WinXP with 5.3-STABLE via Bluetooth using USB dongles. Specifically, BSD box has dongle that is recognized by the ng_ubt with the following trace: ubt0: SiW SiW, rev 1.10/15.00, addr 2 ubt0: SiW SiW, rev 1.10/15.00, addr 2 ubt0: Interface 0 endpoints: interrupt=0x81, bulk-in=0x82, bulk-out=0x2 ubt0: Interface 1 (alt.config 5) endpoints: isoc-in=0x83, isoc-out=0x3; wMaxPacketSize=49; nframes=6, buffer size=294 I followed Handbook, set up and started rc.bluetooth, hcsecd, sdpd and rfcomm_pppd. My dongle is recognized, pairing from WinXP side goes well. Connection from WinXP to FreeBSD can be always established but when I'm trying to send any data over this connection, it drops very soon with the following diagnostics: Jan 22 21:34:49 elrond kernel: ng_ubt_rcvdata: ubt0 - Dropping HCI frame 0x4, len=124.

Invalid channel state, cid=75, state=5 I tried to reduce MTU and MRU for ppp down to 512. It helped a bit - connection was alive a bit longer. Then again, connection dropped with the above diagnostics. Just have no idea where to dig further. Regards, Petr
