HCI Config returns Can't Init device

Hi,
i am using 2.4.18 kernel with the RFMD serial port bluetooth
module. i have ported the Bluez Stack and HCI_H4 protocol modules. The RFMD device is get attached by

hciattach /dev/ttyS0 swave 115200 flow

the patch added in the hciattach.c is soft reset functionality included before sending param acess command in SWAVE function and after that reset again. This attaches my UART dongle with the HCI layer.

When i try to hciconfig uration i am getting the following errors.

hciconfig hci0 up

Can't init device hci0. Connection timed out(110) ERROR.

But i could have functionality with Kernel 2.6. The HCI config works fine.

Is there any patch to imply for the 2..4 kernel.

Please advise
Thanks and regards
Hariharan.v.

Hi Hariharan,

you need at least use my 2.4.18-mh15 patch. However if the 2.6 kernel works then use it.

Regards

Marcel

Hi,

i have patched kernel 2,4,18 with the yours respective patch. Since i am using Samsung S3C2440 processor, smasung officially supports only the kernel 2.4.18. hence i need to get
the best result of bluetooth using this kernel version 2.4.18 only.

Facing the problem is ,

Can't init device hci0. Connection timed out(110) ERROR.

Hi Hariharan,

there is no need to repeat your problem. I don't have a Samsung S3 or a Silicon Wave module (with UART interface) laying around. So I can't help here, but the 2.6 kernel will also work with the Samsung processor and so you should really go this direction.

Regards

Marcel
