All work is based on linux kernel version 2.4.18 (RH7.3/8.0)
(1) Bluez kernel modules: Stable version is kernel 2.1, with "make
update" to update the kernel source. Replace header files under
Q: New kernel version provides a linux kernel patch, but seems it
can not be applied successfully.
A: (update 1/27/03) The bluez new kernel 2.3 can be installed with
some error. Just apply the kernel patch by "patch -p0 < linux-kernel-patch-xxx".
But for linux kernel version 2.4.18-14, there will be errors, just
ignore them. The compile the bluez kernel 2.3, and most modules are
successfully generated except "core.o" and "benp.o". While for
peer-to-peer mode without scatternet, this error will not affect
users. Then make install and you will find out that this baby works
like a sound. (Kernel 2.3 is best for lib 2.3 and utils 2.2. )
(2) Bluez PCMCIA driver: use btuart version 0.2, make modules as
(REMIND: Bluez kernel package can recognize usb bluetooth
devices directly. Modules are hci_uart.o, hci_usb.o and system module
NOTES: For Bluetooth devices with USB interface, like Errison BT
training Kit, bluez already has full support, by hci_usb.o . But
users must remove the "bluetooth subsystem in linux kernel", which is
rm -f /lib/modules/"uname -r"/kernel/net/bluetooth/bluetooth.o
Then the BT subsystem is removed. You can also remove it if it
modprbe -r bluetooth.o , then the bluez subsystem will work, by
modules hci_usb.o and bluez.o.
(3) Bluez lib: new version 2.3 works! This version enhances the lib
(4) Bluez utils: new versoin 2.2 works! Link quality is enabled,
with some more new features.
