[Bluez-users] Make a local network using two Bluetooth USB Dongle

[PC32 YPXin]

Dear All:
	I have made a File Transfer using two Bluetooth USB Dongle(which is =
Bigabyte supporting Bluetooth Spec v1.1) between a linux box and windows =
machine.
	In windows, I can find the BlueDevice in linux and its service(such as =
Audio Gateway, include File Transfer), but I cannot transfer to linux, =
because timeout.
=09
	I do that as the document from bluez.org:
		Get the kernel 2.4.20, and patch it.
		then compile with support Bluetooth:
				<M> L2CAP
				<M> SCO links
				<M>RFCOMM
				<M>BNEP
			Bluetooth device drivers:
				<M>HCI USB driver
				<M>HCI UART driver
				<M>HCI BlueFRITZ! USB driver
				<M>HCI VHCI driver

	make, make install,make modules,make modules_install
	then reboot
	install the bluetools from bluez.org
	and ln /usr/sbin/hcid /sbin/hcid
	/etc/init.d/bluetooth start
	and get [OK];
	Then let windows to search the device, and found it, got its service, =
it was ok. Then transfer file, but failed.
	This is log from hcidump:

                                   =20

	I don't know why the L2Cap(s): Connect req broken?
	Very Thanks

to let others find your service information you need to run a SDP
server. Try starting sdpd.
