Serial Port is a generic = serial port that can be used for arbitrary communication with the phone. = =A0Audio Gateway is for the handset. =A0I do not believe the phone will = attempt to establish an SCO connection with a device that is not = connected over one of the Audio Gateway channels.

here is one of the moment
did i must bind rfcomm to = phone channel where the serial port is shown or to where the audio = gateway is shown ?

I am not sure if = that will work, unless the phone recognizes your computer as a handsfree = device. =A0Normally there is a step in the phone where you have to add a = handsfree device, and then you have to go through a handshake on that = channel.

Also, make sure that you are connecting to = the correct channel. =A0If you run=A0

You have to connect to (or bind in your = case) to rfcomm channel 7 (in this example). =A0Otherwise, the phone = will not recognize that you are trying to connect as a headset. =

Second, you have to complete the handshake = defined inside of the bluetooth headset profile. =A0Once again, = otherwise the phone will not recognize you as a = headset.

There are a lot of little gotchas like = this that are kind of hard to track down. =A0Once I figure them all out, = I hope to write an article on my site, alongside of the code I release. =

well = the things i want to make samethin like phonecontrol.net in windows =

for managing telephone and other there is a good tool = gammu

and when the call comes or maked i want to establish audio = connection

so i want to make it work after HF profile is = registred and listening service is running
as i understand the audio = is channelles

the listening service is the = goal

2007/9/14, andrey = larin < = ubergitler@gmail.com>:
well
what i = do..
in gentoo and testing 2 phones SonyEricsson-w800 and Nokia = 5200

install bluez

registered HF service using = sdptool

using hcitool and sdptool
finding phone and it rfcomm = channel
on phone i set that my pc is can always connect to = phone
binding using rfcomm to /dev/rfcomm0
and just using = minicom

i even make a stupid script in bash to connect to rfcomm = on phone

when the ring comes i try at command to request audio = channel

but nothing

maybe same thing foget to = tell

2007/9/14, robert = < = rbscott@cadvium.net>:
Hello Andrey,

let me back up for a = second and ask how you are trying to access the
handsfree?

Is = the phone paired with your computer?
Is the phone paired with your = computer as a Handsfree device?
What kind of phone are you using? =
For your RFCOMM channel, are you connecting to the = channel=A0=A0channel
are you connecting to on the phone?
How are = you handing the RFCOMM processing?

I left out some steps about = Service Discovery and Pairing that I
assumed you already = completed.
