Activating speaker phone from application in S60 5th edition

[pedramz]

My application dials a number and I want to activate the speaker phone when the other side has answered. I do this in S60 3rd edition by sending a key event from my application to the Telephone application.
I am now implementing the same behavior in S60 5th edition (N97 at the moment). The key event would not work here because none of the softkeys are used for activating the speaker phone. I think sending a Pointer event positioned over the speaker phone button should work but I have not succeeded yet.

Has anyone tried this?
Or has anyone a better solution?

Thanks,

Pedram

With 3rd edition would would be better using this one: http://wiki.forum.nokia.com/index.ph...he_loudspeaker

Dunno if it works on 5th ed, anyway, feel free to try out..

try using the CallAudioControl API, it has a function to activate loudspeaker.so call that function when call is in answered state.

Download that API from S60 3rd FP1 or FP2 plugin

Thank you!

Can you tell me where I can find TelephonyInternalCRKeys.h ?
Or any other header file where the values for KTelephonyAudioOutput and KTelephonyAudioOutputPreference can be found?

I think the reason I used key events in the first place was that I had problem finding those two and I assumed they were not public.

Check the link again, the Api plug-in link is near the top of the page

The page mentions that there is a "CR Keys To Control Phone Volume API" which also includes keys for routing the voice call between the earpiece and the loudspeaker. I downloaded the extension plug-in packages but the only related plug-in that I find is TwoCenRepKeysToControlPhoneVolume.ZIP which includes a header file TelephonyInternalCRKeys_partners.h and this file does not have KTelephonyAudioOutput or KTelephonyAudioOutputPreference.

Is it possible that it was removed and we are supposed to use Call Audio Control API instead?

have a look into this thread: http://www.forum.nokia.com/forum/sho...d.php?t=154127

Thanks. I found the correct header file in Shared Data API.
Unfortunately setting the central repository values with these keys do not work in S60 5th edition.
I am going to try using Call Audio Control API.

im sure CallAudioControl will work for you

It seems that I would need MultimediaDD capability to use CallAudioControl. Is that correct?
In that case I would not be able to express sign.

hmm..i doubt its need, just give it a try without multimediadd

i think Writdevicedata capability required for your operation

I think my problem might be something else. What I want to do now is basically as follows,

// This is in my header file
CCallAudioControl *iCallAudioControl;


// In ConstructL
iCallAudioControl = CCallAudioControl::NewL();


// And to activate loudspeaker
iCallAudioControl->SetOutput(CCallAudioControl::ELoudspeaker);

Compilation goes well but on the installation I get "Unable to install" in the last moment. I get this as soon as I have the NewL line in my code.

Am I missing something?

have you installed a supporting sisx for callAudioControl which came with plugin
