Full duplex at BlackBerry JDE 4.7

Hello,

I know that sound duplex (playing and recording at same time) isn't supported at BlackBerry JDE 4.6.

I saw the article - 'Not sure I it is a bug or a feature. We use two players: one to record, another to playback', but I could not find the solution.

 

Does anyone know how to implement the application with the sound duplex?

Or, Does the BlackBerry JDE 4.7 support the sound duplex?

 

Thanks.

Regards, Ricos.

Yes. It is possible. Play and record on two seperate applications. Oh, make them background applications.

Is it impossible to implement the sound duplex in one application?

Thanks for your  reply.

 

I implement the full duplex with two applications(play and record application) according to your reply.

So playing and recording is done simultaneously on phone.

But when I count from one to ten, some digits isn't recorded.

I tested it on BlackBerry Bold 9000.

 

How do you think about it?
