Hello all,
We are presently working on Silicon wave Serial Port Bluetooth module
with Linux version 2.4.20.
When we try to attach the UART with HCI layer.
Bluetooth module : Silicon Wave bluetooth module. (H5 3 Wire interface)
Linux Kernel : 2.4.20.
We have done different trial with the module. Below we have given two
of them major, that we have noticed in our experiment.
Experiment 1:
When we connect Bluetooth module with the full functional serial port
(thatr contains Hard ware flow control)
The HCI layer is attached with UART layer.
But when we try to UP the HCI0 it returns
cannot Init Device hci0.
Experiment 2:
When we connect the Bluetooth module with 3 WIRE serial cable (consist
of TXD, RXD and GND)
hciattach /dev/ttyS0 swave 115200 noflow
Actually our plan is to work the bluetooth with 3WIRE (H5) Bluetooth interf=
ace.
Kindly confirm whether the HCI_UART_3WIRE functionality is included in
the linux kernel.
if possible, adivse us a path to fix this issue.
This application returns=20
Initializaion timed out.
Advise to fix it
Thanks and regards
Hariharan.v.

actually nobody implemented the 3-Wire UART support for BlueZ.

Hi Marcel,
Actually we are using the Silicon wave Bluetooth device that is
compatible with the
BCSP when it configured for 3 WIRE H5 protocol.
As per our study on 3 WIRE protcol (H5 ) from bluetooth.org
specification. The H5 and BCSP seems to be almost same except the
protocol number and Initialization process.
we handled the Initialization process (SYNC and CONFIG) in hciattach.c.
As per the document, the device is in Uninitialized state. We have to
SYNC and CONFIGURE
in order to make the device into ACTIVE mode.
Please verify it and confirm us whether we are anything wrong,
The H5 3 WIRE UART Transport layer specification document is attached
for your kind
reference.
Thanks and regards

please send an unified diff for the hciattach changes.
Is this statement "3-Wire UART differs only with the protocol number
definitions" really true? If yes, it should be very easy to integrate
the 3-Wire UART support directly into hci_bcsp.c without any unneeded
overhead.

Hello All / Marcel,
We have changed the hciattach.c and hci_h5.c (H5 3 WIRE UART Bluetooth driv=
er).
The Bluetooth module is up. We could read the Bluetooth device address
and scan the
bluetooth network.
Thanks marcel for your valuable support.
Now we are facing the general problem.
we are trying to run SDPD daemon, it fails.
we could not able to browse the bluetooth network.
This SDPD fail occurs, when we use the USB Dongle also.
We have only changed the hci_h5.c and hciattach with new name of the
dongle (H5 3 WIRE).
Our specification :
Kernel - 2.4.20.
For information:
we run sdpd
then we try to kill sdpd, it returns NO PROCESS is KILLED information.
Advise us.

Thanks and regards

this kernel version is a little bit problematic. Do your development
with the 2.6.12 kernel and then backport it. Otherwise nobody will
review it and it may become useless.

You add the basic configuration stuff to hciattach like it was done for
BCSP and then you set the TTY line discipline to N_HCI and switch to the
3-Wire UART protocol. However this must be implemented in hci_3wire.c
and linked correctly into the hci_uart.ko driver. The complete protocol
handling then has to be done inside the kernel.

Host side -> SYNC Command -> BT Device=20
Host side <- SYNC Response <- BT Device
Host Side <- SYNC Command <- BT Device
Host Side -> SYNC Response -> BT Device
Host side <- Config Command <- BT Device

Here after the device does not respond for any of the commands
Please advise us whether our command sequence for the HCI attach of 3 WIRE

Our progress plan in the Implementation of H5 3 WIRE in Bluez.
First we attach the module HCI layer with the bluez stack.
Second we build the driver to usr 3 WIRE stack.
our plan is a proper one or not. Advise.

look at the hci_h4.c and hci_bcsp.c files for examples. They show you
how to use our HCI UART API. The number of lines of code are very small
and it should be easy to understand what the callback functions are for.
The hciattach.c is a little bit more freaky. I need to split it into
more separate files for each transport or vendor.

Definitely follow the existing BCSP code. You should find you can
adapt it for 3WU with a minimum of difficulty. Some of the constants
are different (British humour doesn't always travel well) but otherwise
the core design is very similar. 3WU has some weird additional options,
but you probably don't need those.

create a file drivers/bluetooth/hci_3wire.c and start with BCSP as base.
In general you can do a driver that supports BCSP and 3-Wire at the same
time, but actually I really like to have two separate drivers. Try to
start from scratch and don't copy too much things. The second part is
adding support for 3-Wire to the hciattach program.

Hello all,
we wants to develop and implement the 3 WIRE UART support for the=20
Bluez Stack. can any one suggest an idea to develop and implement
3 WIRE UART in BlueZ.=20
May i follow the H4 UART Implementation with Some modifications related wit=
h=20
H5 (3 WIRE UART). We came to know that Packets has to be added before and a=
fter
the HCI commands according to H4 and H5 UART. Is it right ?.=20
We wish to know that whether it takes major development cycle.
As per Silicon wave datasheet the 3 WIRE UART is compatible with BCSP.
May we have to follow the H4 UART or BCSP one for our development.
Advise us.
Thanks and regards
Hariharan.V
