Okay this is what I've been wondering...is there anyway to use an Android phone as a bluetooth headset for the Galaxy Tab (or any Android tablet for that matter)? im planning on getting T-Mobile's prepaid Android 2.2 phone and i want to keep my minute usage down by using Google Voice on the tablet. And since they both have bluetooth capabilities it should be possible to use it in this manner, right? I do not want to use one of those hideous, uncomfortable bluetooth headsets because im already going to have a bluetooth device (the phone) with me that im more comfortable using. Is there any way to do this or an app that enables this functionality?

no because your not forwarding your calls, your handling the call over bluetooth. this is what im talking about: people will call my tablet's Google Voice number, and I will be able to use my phone as a bluetooth headset for the tablet to take the call

its the same concept as bluetooth headsets today:
-you get a bluetooth headset
-you pair the headset with your phone
-you take calls on your phone but talk and listen through your bluetooth headset

the way im trying to do this is:
-you get a bluetooth-capable phone
-you pair the phone with your tablet
-you take calls on your tablet but talk and listen through your bluetooth phone

since the phone already has everything that a bluetooth headset has--microphone, earpiece, bluetooth radio-- it should be able to pair with the tablet and work in the same manner as a regular bluetooth headset

I have been looking to do the same thing with my Samsung tab. Instead of walking around stucked to my face.

Yes I could use a BT headset, but it won't dial out. There is a specific Bluetooth profile to do this.

i don't know much about this, but wouldn't the phone would need the bluetooth protocol that a headset uses? someone would have to make a program that would allow the phone to be used as a headset, but then also decide what gets priority if the phone needs to also access the mic or earpiece when you are on a call...

i don't mind simply using a bluetooth - that is more comfortable and flexible than me holding a phone in one hand.

I'm looking for a solution to this as well. But a different application.

using a tablet as a car-computer.

leave phone in pocket. take and view phone calls though tablet, which is mounted to dash, which is routed to the car audio system with strategically placed microphone built into dash.

I'm surprised no one has made this... seems like something many would be after.

The Phone app apk is there but it doesn't work Honeycomb, Google Voice also FCs. I think it's because Google knows it would take away from the Android Phones and that would piss off the carriers.

What we are seeking is the Bluetooth HFP (Hands-Free Protocol) (ver. 1.5) HF Profile. Many newer OEM car head-units support the HFP hands-free (HF) mode while most all Android devices and tablets support the audio gateway (AG) mode only.

I am not a developer but I would suspect that getting the AG portion of HFP to work would require changes to the BT drivers. If anyone has the HF mode working on an Android device, please chime in!

Do any devs have ideas? This would make tons of tablet owners happy. In an ideal world, we would be able to keep an Android phone in our pocket, and send/receive texts on the tablet through our phone carrier, as well as make and receive calls using our tablets as a Bluetooth speaker phone. This marriage of tablet to phone would be awesome, and generate a lot of money and interest in the app market.

Does anyone know if there has been any progress on using a phone as a bluetooth headset for a tablet? I am trying to figure out how to do this with a samsung galaxy gio and a samsung galaxy tab 7.

This is the exact solution I am looking for! Come on developers of the world, how hard can it be! ;)

So is the problem with this that Android doesn't support the necessary profiles in its bluetooth stack? Is there any way to add the profiles ourselves?

It would be nice if a developer would look into this.

    @swDevCPT: It shouldn't need any ROM editing. It could well need root, and Xposed (if we didn't have xposed, then the chances are much higher that it would need a ROM edit). The reason why I'm thinking it will need that is because the standard Android Bluetooth APIs only provide access to the RFCOMM protocol and certain controls surrounding using a headset with the phone (but as far as I see, no possibility of using the phone as a headset itself). The problem is that RFCOMM is a different profile than the headset and hands-free profiles - not to mention the headset and hands-free profiles are realtime, while RFCOMM is not. That should also answer your question @ulao2 - if we go with the normal (realtime) profiles, then latency (and quality) shouldn't be a relatively big problem.
    One thing I ran into the JSR-82 specification. Although I get a strange feeling Android doesn't support it, it is something I will be checking out in the next while. Not to mention, I'm not even sure it would be doable with those APIs, even if Android supported them. While they do seem to offer more flexibility, I haven't read/understood far enough to see if that would be able to do it (this was, again, something I stumbled on when I was actually looking for something else, so my first reading of the document was not with the intention of using it for this).

    Some Info

    Hi.

    Google launched the Google Glass and it has an app, as you may know.

    You can call from the google glass, recieve texts and stuff.
    i runs over bluetooth

    "MyGlass" its what we need right?

    see this page http://www.androidpolice.com/2013/0...oice-support-and-pushing-navigation-to-glass/

    So what we need is a port for MyGlass

    there must be a way to tell our phones that the other phone (in my case i want to do this with my tablet) is a google glass

    http://forum.xda-developers.com/showthread.php?t=2298214 i found that.
    the name of that page is: Run Google Glass on your Android phone

    i hope we can recieve calls and messages from out phone to our other phone (my case is a tablet)

    I havent tried because my internet is limited

    other thing that we can do is simulate that our phone (in my case is a tablet) is a car phone, if we can tell other devices that our bluetooth device is a ps3 controller and is a keyboard and mouse why not a car phone?

    EDIT: i just saw an apk in android police, its called GlassBluetooth.apk its from the system dump of the Google glass
    here the link http://www.androidpolice.com/2013/0...em-dumps-please-do-something-cool-with-these/ that might be useful i'll try it tomorrow

    Sorry for my english.
