Ringtone or CallerID to Bluetooth?

Post by SoundAbout on Thu Apr 03, 2014 1:05 am

The caller ID and ringtones won't work on a Bluetooth device (car), or a Bluetooth headset when it supports phone calls (even it the headset supports A2DP media).  

Ringtones may go to a Bluetooth headset via A2DP if the paired Bluetooth phone profile is un-checked in the phone settings.

It will also work if the manufacture has done some tweaking.  

What happens is the phone rings, and Android sends a notification to the connected Bluetooth phone device.  The device usually has its own beep or notification.   Android will stop any audio from going over Bluetooth SCO (mono) and Bluetooth A2DP while the phone is ringing.  

The only time this may work is when the Bluetooth headset manufacturer puts some firmware into the headset so that it can read contacts over Bluetooth and say them through the headset.
 
I've tried temporarily disconnecting Bluetooth mono while the phone rings to get it to go over Bluetooth A2DP.  That won't work either.  Once the phone starts ringing...its too late.

If the headset supports both Bluetooth protocols, then the ringtone won't be heard using A2DP unless the manufacturer has done some special tweak.

You can block the speaker from getting the ringtone. Since the Bluetooth SCO (mono) takes control as soon as the phone starts ringing, you have to do this:
1) Open SoundAbout
2) Press "Alert behavior"
3) Press "Bluetooth (mono) behavior"
4) Press "Ringtones to"
5) Choose "BT ringer (phone vibrate)" or "BT ringer (phone silent)"
