[Bluez-users] Trying to connect using a BCSP dongle

[Bluez-users] Trying to connect using a BCSP dongle

[Turley, Scott-P27856]

[-- Attachment #1.1: Type: text/plain, Size: 333 bytes --]

Hello all,

I'm trying to connect a bluetooth module using the BCSP transport on a
Linux machine.

I have all my services running, but when I try notifying the Linux bluez
stack that the transport will be bcsp using:
"hciattach ttyS0 bcsp", the Linux PC locks up.  I have to reboot to
recover.

Any suggestions?

-Scott

which kernel version do you use. Can you call "dmesg -n 8" and try it
again from the console to catch possible error messages from the kernel.

I'm using kernel version 2.6.9-5.EL (kernel for RedHat Enterprise v4.0).
Here's what shows up in /var/log/messages:

Bluetooth:  HCI device and connection manager initialized
Bluetooth:  HCI socket layer initialized 
Bluetooth:  HCI UART driver ver 2.1
Bluetooth:  HCI H4 protocol initialized
Bluetooth:  HCI BCSP protocol initialized

Then it hangs.

When I type in:   hciattach ttyS0 any 115200

It doesn't crash, but it doesn't work either.  I get a slew of:

H4_recv:  Unknown HCI packet type c0
H4_recv:  Unknown HCI packet type db
...
