[Bluez-users] Serial(HCI-UART) Bluetooth Module - Initialization timeout error

[Bluez-users] Serial(HCI-UART) Bluetooth Module - Initialization timeout error

[Benny]

Dear all,
            
We are now working with a RFMD Silicon wave based serial(hci-uart)
bluetooth module.  We are trying to test for its working under linux
2.6.  We have installed the Bluetooth stack (bluetooth.o) module and
the HCI Uart (hci_uart.ko ) module.
We have tested for the working under windows.

When we try to do hciattach the device with Serial port using the
following command.

             hciattach  /dev/ttyS0 swave 115200 flow

we are getting the INITIALIAZATION TIME OUT error. And it is the same
result with the following commands also:

             hciattach ttyS0 swave 115200 flow
             hciattach  -s 115200 ttyS0  swave 115200 flow
             hciattach /dev/ttyS0 swave 115200
                      
Has anyone faced this problem before. Any pointers? Please advice.

Thanks and regards
Benny

Silicon Wave or now RFMD never send me a development kit to improve the
support for it. I only have Silicon Wave based USB dongles and most
people I know uses the USB interface to attach a Bluetooth module with
this chip.

Look at the hciattach source code and see where this error occurs. Check
your kernel config and make sure that H4 is really configured:

	CONFIG_BT_HCIUART=m
	CONFIG_BT_HCIUART_H4=y

Regards

Marcel

Thanks Marcel for your reply. Yes we doing the same exercise debugging
step by step using the hciattach source. Yes we have chosen the
required configurations mentioned.

We are designing a Bluetooth remote device using a custom hardware
interfaced to a standard Bluetooth module(headset+SPP). We are
targeting this product for PC market.

So we have to suggest our customer a set of USB Bluetooth dongles
which supports Bluez on the Linux PC. We are finding that the CSR
based BT USB dongle is working fine under linux rather than the
SiliconWave based BT USB dongle. I may be wrong in this regard, I
might have missed some settings.

We have tried the following BT USB dongles:
i) unknown make(CSR)  - Woking fine for Audio and data transfer.
ii) Orchid (Silicon wave) - Not working for Audio but recieving data.
iii) ANYCOM USB Adapter 240 (Silicon Wave) - Not working for Audio as
well as data.

We are using linux kernel 2.6.9-1.667(Fedora Core 3) and using the
latest CVS BT-SCO drivers.

Please advice.

Thanks & Regards,
Benny

the ACL part should work for any dongle without any problems. I have one
of the Anycom 240 adapters by myself and the data part is working fine.
For the SCO support you should really go with CSR based dongles, because
the Silicon Wave seem to behave somekind of strange. However I am not
fully working on this topic.

Regards

Marcel
