[Bluez-users] Problems with RS232 and BT - Can't init device hci0

[Bluez-users] Problems with RS232 and BT - Can't init device hci0

[zubiwat]

I have CSR chip connected to my PC by RS232
When try to use hciattach /dev/ttyS0 any 921600 flow I always get:
hcid[2594]: HCI daemon ver 2.4 started
hcid[2594]: HCI dev 0 registered
hcid[2612]: Can't init device hci0. Connection timed out(110)

When I use hciattach /dev/ttyS0 csr 921600 flow I get:
Initialization timed out.

I also tried to setserial /dev/ttyS0 baud_base 921600

What is the problem because i red almost every howto and mail on mailing list. 
I only get some signals from the device but he can't analize what is it.
Im using bluez-libs 2.5, bluez-utils 2.4  with kernel 2.4.22
Please help me!

try this:
$ strace -eopen hciattach /dev/ttyS0 any 921600

and watch, what's wrong.

are you sure that your ttyS0 is capable of more than 115200 baud?

Hi Maciej

try to run "hciattach ttyS0 csr". If your Bluetooth chip really boots
with 921600 baud you have to buy a serial card that is capable of it.
