Hi Cyril,
Yes The bluez works perfect. It=B4s compilated and all utils are in the =
module.
I am sure that the error is stupidity of the configuration.
For the moment, It=B4s wins Sir Graham 0 GumStix 1
I hope I find the problem soon.
Thanks for you help.
Regards,
Sir Graham.

Are you sure craig didn't compile "bluez-utils" with specials options? =
Have a look at the file named "bluez.mk" in the directory "make" of =
the buildroot... It can be there.
Your gumstix will work well step by step, it's a matter of patience!=20
It cost us months to make all the serial ports and the sound working =
well!

Hi Cryril,
Yes. You scripts works. But now there is other problem. If the =
bluetooth script S30bluetooth is executed in the boot the ttyS3 don=B4t =
work.
We try to rename the S99SpecialConfig to S29SpecialConfig to execute =
before the S30bluetooth but the results is the same.
If we rename the S30bluetooth to s30bluetooth (desactivate this =
script) the /dev/ttyS3 works perfect.
The case is that we need the ttyS3 to connect a serial bluetooth =
module (support by Bluez) in H4 format (noflow). In the Red Hat this =
module works
perfect but in the gumstix we don=B4t know how the S30bluetooth must =
be configurated.
Any idea....?

Sir Graham.

Hi Cryril,
Here you are.
# cat /proc/gpio/GPIO4[6789]
46 GPIO in set
47 GPIO in set
48 AF2 in set
49 AF2 out set
Very bad!=20
Neither ttyS2 nor ttyS3 are configured correctly!=20
It's normal that you don't have anything on your output
=20
The correct configuration would be:
# cat /proc/gpio/GPIO4[6789]
46 AF2 in ...
47 AF1 out ...
48 AF1 out ...
49 AF1 in ...
The GPIO 46-47 are for ttyS2, 48-49 are for ttyS3.
Set them all correctly using the magic formula:=20
modprobe proc_gpio
echo "AF2 in" >/proc/gpio/GPIO46
echo "AF1 out" >/proc/gpio/GPIO47
stty -F /dev/ttyS2 -ixon speed 115200
echo "AF1 out" >/proc/gpio/GPIO48
echo "AF1 in" >/proc/gpio/GPIO49
stty -F /dev/ttyS3 -ixon speed 115200
A better approach is to create a file in "/etc/init.d" named =
"S99SpecialConfig" with the following content:
#------------------------------------------------------------
#
# Special config
#
start() {
modprobe proc_gpio
echo "AF2 in" >/proc/gpio/GPIO46
echo "AF1 out" >/proc/gpio/GPIO47
stty -F /dev/ttyS2 -ixon speed 115200
echo "AF1 out" >/proc/gpio/GPIO48
echo "AF1 in" >/proc/gpio/GPIO49
stty -F /dev/ttyS3 -ixon speed 115200
}
stop() {
}
restart() {
stop
start
}
case "$1" in
start)
start
;;
stop)
stop
;;
restart|reload)
restart
;;
*)
echo $"Usage: $0 {start|stop|restart}"
exit 1
esac
exit $?
#-------------------------------------------------
That what we made on our gumstix and it work perfectly. Since =
that, we don't worry about ttyS*.
Don't hesitate to tell us if it works or not. But, it should work.
If it doesn't verify the state of your GPIOs.
> we have the Build 516. Where are the configuration of the =
Second port, what is this configuration... and Why don=B4t work like the =
the first port?
That's a classical GPIO problem, the processor of the gumstix : =
Intel PXA255 can do different things using the same input/output.
For example, it can do bluetooth I/O or Serial I/O on the same =
connector. So, you need to configure by hand if you want the first or =
the second.=20
We will connect a bluetooth module to the second port.... We try =
this module in a red hat with bluez and works perfect. But I can=B4t =
configurate
the second port to works with bluez.... =BF?
After looking at your GPIO configuration the verdict is: =
Hopefully, it doesn't work! Else the problem would be very strange.
To test, you should try to communicate with a PC using =
hyperterminal or minicom.
Regards,
Sir Graham.

Could you show us a copy of the state of your GPIO?
From memory, use this command:
cat /proc/gpio/GPIO4[6789]
And a copy of the state of your ttys (from /proc/driver/...) =
before and after sending these commands:
echo "FooBarBaz" >/dev/ttyS2
echo "FooBarBaz" >/dev/ttyS3

I fogot that we added the patch for ttyS3 (look at =

Hello,
To configure the serial port ttyS2 and ttyS3, we used =
these command:
modprobe proc_gpio
echo "AF2 in" >/proc/gpio/GPIO46
echo "AF1 out" >/proc/gpio/GPIO47
stty -F /dev/ttyS2 -ixon speed 115200
echo "AF1 out" >/proc/gpio/GPIO48
echo "AF1 in" >/proc/gpio/GPIO49
stty -F /dev/ttyS3 -ixon speed 115200
(Replace the speed )

Verify the configuration of the relevant GPIOs too. =
From r374 on they should
be set to uart, but before you had to do it manually =
(see the tips and tricks
