Can't connect to cell phone using dbus api

Can't connect to cell phone using dbus api

[Rafael Seste]

Hi all,

I'm trying to connect to my cellphone (nokia 5310) using the Dbus api.

First of all I created the device (org.bluez.Adapter.CreateDevice) and
it worked but it didn't request the pin code. The simple-agent was
running.

Then I tried to connect using org.bluez.Audio.Connect but it returned
the following error:

Error org.bluez.Error.ConnectFailed: Headset connect failed

I tried to change the profile to HeadsetGateway
(org.bluez.HeadsetGateway.Connect) and got this output:

Error org.freedesktop.DBus.Error.UnknownMethod: Method "Connect" with
signature "" on interface "org.bluez.HeadsetGateway" doesn't exist

Isn't it possible to connect with my cellphone? it has HSP/HFP.
Am I doing something wrong???

Thanks

You'd need to use CreatePairedDevice if you want to pair. simple-agent
will also do it for you if you run it as "simple-agent hci0 <address>".

That's because your phone isn't a headset :)

The Audio interface at the moment only supports headset-like devices but
not devices having the opposite role (i.e. those that usually connect to
headsets), like your phone.

I think you'll need to explicitly enable the the experimental support for
that interface by adding Enable=Gateway to /etc/bluetooth/audio.conf.
However, even then you're likely to bump against problems since as I
mentioned the support is still completely experimental.

It is but the audio profiles don't really work yet. Other profiles your
headset supports will most likely work better.

How can I create a PairedDevice using shell script?
object CreatePairedDevice(string address, object agent, string capability)
I don't know the parameters that I need to pass. What are object agent
and string capability?

thanks for the help.
I enabled the gataway and everything worked.
It was possible to make a call too.

Another question.
How can a get the audio from a call??? When the phone answer it
disconnect from the bluetooth.
