Bluetooth AD2P Phone call with phone mic enabled.

Post by Mako79 on Tue May 07, 2013 10:11 pm

Hi everyone. I have purchased the full version SoundAbout.
In summary, is there an option to control the phone mic?

Scenario
I have purchased http://www.amazon.com/Adapsonic-Bluetooth-Cassette-Adapter-Streaming/dp/B008PUPBF6 AD2P Bluetooth cassette tape. It does NOT have built in mic. Please dont ask me to upgrade the head unit as the unit is a stock BOSE system with its own loom/harnest.

The AD2P stereo streaming is fine. When a phone call is received, i can only hear the person via car speakers. They cannot hear me as the head set profile (HSP) automatically assume the the bluetooth device has a built in mic and turns the phone mic off.

Is there anyway Soundabout can nominate the phone mic?

Thanks for your time in advance.

Android won't allow audio to be sent to Bluetooth A2DP during a phone call, so this cassette device must support both A2DP for media and also Bluetooth SCO for phone calls.

If a Bluetooth mono SCO device, is being used for a phone call, Android forces the Bluetooth mono SCO microphone to be used. The audio profile manager will not allow a switch to the phone's built-in speaker, when Bluetooth is being used. I'm surprised the device doesn't have a microphone somewhere in the receiver.

I wonder if Apple allows the phone mic to be used with Bluetooth and that is why this product doesn't have a microphone?

Thanks Dave
I had this cassette specially shipped from the US as they are not available in Australia.
I didn't read carefully in the description that it did not come with a built in mic.
I assumed thinking that all AD2P should atleast have a built in mic. I too was surprised.
Thanks for your timely response.

I wish Android would allow phone call audio to be played over A2DP devices. My guess is that they don't allow due to feedback concerns.
