My situation:

  • Android (4.0.3) tab hooked up to my car stereo using the headphones connector.
  • Android (2.3.5) phone (HTC Desire HD), which I use to call, text, browse, etc.

Since my car stereo's Bluetooth device died I thought I could use the Android tab as a audio relay device. Problem is: the tab has no Bluetooth. It has wifi though.

Is there any way to use an Android device as a handsfree adapter over wifi? Some kind of wifi relay between the phone and the tablet, perhaps?

Am I right that you basically want to make phone calls from you tablet that are relayed to you smartphone? – Flow Jun 10 '12 at 16:07
I think he wants to connect to the tablet using Wi-Fi, and control the tablet (music choice, volume, etc) as if it were the bluetooth head-end of a stereo. So the tablet plays the music, but the phone controls the tablet's audio. – jlehenbauer Jun 12 '12 at 1:19
no. both wrong. I want to make a phone call with my phone, but in my country it is illegal to hold your phone at ear height. That is why I had a car stereo with bluetooth, so I can hear the person I am talking to over my car speakers. – spambas Jun 12 '12 at 9:55
EDIT: I need to replace that function and I already have a tab in my car directly connected to my stereo. I want my outgoing audio from my phone over wifi to my tab. phone-> wifi -> tab -> cable -> car stereo. If I can dial from my tab that would be an extra. – spambas Jun 12 '12 at 10:04
Nobody? Is it that strange? – spambas Jul 3 '12 at 9:59

Id like to do exactly what your are saying. Have my phone synced to my tablet using wifi or bluetooth and use the tablet as my handsfree interface for phone There is this app but its still in its easrly development phase although those that have used it say its not too bad and has plenty of promise

I was planning to wait for this to be released as a full release, but it is taking a little long. Any other ideas? – spambas Sep 7 '12 at 13:59

Does the tab has USB port. How about adding an external custom BT device. BT device talks to android app on tab via any serial library for example scm (
