  • Tablet As Bluetooth Headset

    Okay, so now that Android tablets are getting more popular for in-car use, maybe it's time to propose this on here.

    Some of us have Parrot kits and whatnot for bluetooth in the car, but for people using Android tablets, the easiest solution, if it were to exist, would be having the tablet itself serve as a bluetooth headset. This would effectively give you phone conversations over your car speakers, and you could either use the existing mic on your tablet, or you would wire an external one in.

    Unfortunately, nothing like this exists so far. There's solutions for seeing your SMS messages on your tablet, but nothing for voice. This appears to be because unlike the bluetooth stack for Windows, the bluetooth stack for Android does not support the Android device itself being used as a bluetooth headset. This concept has been brought up on XDA multiple times, but so far, no developers have picked up this project.

    Now, I could be completely talking out of my butt here, since I am not a developer, nor will I ever be, so please bear with me. I've seen some pretty crazy things done with Android, and it doesn't seem like modifying a bluetooth stack would be impossible. After all, somebody wrote that stack, right, and supposedly it's all open source, right? But whatever, let's say it's impossible. How about with the recent merge of the Android kernel with the Linux kernel? I've probably used Linux for about an hour in my entire lifetime, so I'm not sure what all capabilities it has, but I would assume that if the default Windows bluetooth stack has support for headset profiles, Linux probably does, too. Would the kernel merge make it any easier for a developer to get this done now?

    Forgive me if I sound really stupid, but I just really want to see this accomplished. It seems like it would be useful to a good portion of the CarPC community, so surely I can't be the only one.

    that is a great idea, I have been trying to find something like that but without success...

    since we don't have a developer in our car pc community who would be willing to make it possible, the only solution for this I think is to make a bounty...

    gather money and offer it on xda to get this working...

      i have got it done with a bluetooth dongle (bluesoleil 5.1)But thats not an option on tablets... i am using wifi to make calls from pc as well. maybe you could use wifi connection as well if you phone is a smartphone! But you will need a modem that way!

        Good idea. I can't offer much myself, but maybe we could get a good amount by combining a multiple pledges.

        Yeah, Google Voice via WiFi tethered through the phone is an option, but that uses a different number. It would be much simpler if a Bluetooth solution existed.

          Sorry to bring this thread back from the dead, but was anyone ever able to figure this out? Also, for seeing your SMS Messages, what app(s) are you using?

          If not, maybe we should propose this idea over on XDA.

            Tablet talk. It's not free and it's not perfect. But the developer is dedicated and constantly adding features. He recently added dialing and call receiving. The only problem is, it still uses the phone for communicating, the tablet can only acknowledge the call, or dial the call, but the actual talking and listening would be done on the phone. It's not quite what we are all looking for, but as close as it comes for now. Here is a link

              Yeah, I still haven't tried Tablet Talk out, but I'm going to soon, I think. While I would love to have the audio routed through the tablet, too (and I hope it eventually is), I am going to be trying to install a bluetooth module into my car as well, so that combined with Tablet Talk should take care of the problem for me. I've tried to install that module a couple times before and could never get the wiring right, but I think I know what I was doing wrong now, so hoping to get it working the next time I try.

                Thanks for the info on Tablet talk, too bad it doesn't route the audio to the Tablet :-(.

                I am going to see what I can find/develop with this... if I can't go anywhere, I think I will just be stock using a BT headset with a 3.5mm output into my EQ and I'll have to switch the input on my EQ when a call comes in. Then the Microphone of the BT Headset I will extend the wires of it and run the mic to my gauge cluster for talking on the phone... I'll just have to answer the call on my phone and switch the input on the EQ.

                Also, if you want to follow updates on this either go to my CarTab worklog, or check this post on XDA - http://forum.xda-developers.com/showthread.php?t=844605

                  That's certainly an option, but it might be easier to just get a module that's built for that. Just don't get one that nobody has ever heard of, like I did (I got the Schoshe BT800). That way, you don't have to worry about switching inputs and all that jazz.

                  I'll definitely follow your progress. Good luck!

                    That seems to be the best option as of now. you can still answer and initiate calls on the tablet so as long as your phone is paired with the external bluetooth device tied into the AUX input on the EQ, all you have to do is hit the source button on the EQ. Plan on doing this same thing with my setup

                      HI, i 'm looking for the same possibilities.
                      I have a carpc in the car with windows sistem and Centrafuse software. I can listen the music, use navigation, passengers can watch video, play games, with 3g dongle or Wifi connection can use the internet. I can connect my phone via Bluetooth for hand free call ect...When I call or recive the call music automatic mute and play on when cals endet. The Same with the use of Navigation.

                      I like this:
                      1:Combination: Android phone and Tablets.
                      Advantage of tablets compared with standard Carpc is lower price and does not require the sometimes complicated installation, and takes up little space. And tablets can be used in home, on vacation in hotel, camping, at work...
                      For tablets you need only Car Suction Cup Tablet Mount and connection audio out on tablets and audio in on car radio.
                      But it is also true that you have to remove the tablets when you leave the car and still again mounted. Whit carpc just turn on the car and drive away.

                      2:Combination: MINIX NEO X5 : http://www.focalprice.com/EH0099B/MI...304ATV_EH0099B
                      and 7" Touchscreen Android touchscreen : http://www.cartft.com/catalog/il/1597

                      MINIX NEO X5 has 1 x Headphone jack for audio out to car radio aux and 1 x Microphone jack for external Microphone for lphones call.
                      In this variant I see the problem that the touchscreen use Bluetooth connection to touch work. And I think it is not possible also connected Phone with Bluetooth.
                      Other problem is that MINIX does not have a built-in GPS receiver for Navigation apps. But you can use one USB external.
                      And MINIX can be used at home as a Android TV Player BOX

                      But the biggest problem is that there is no android apps like Centrafuse to use the Tablet as a carpc.
                      I'm surprised that no one software developer thought of this, because Android hardware has great potential for incar use.

                        I've been looking into something like this too.
                        I have a 7" Android Tablet mounted in the car connected to an amp via standard ISO connectors which I made up myself. This setup allows me touse GPS, media etc... exactly as you describe. both the phone and the car have TabletTalk which works well as far as connectivity, but the lack of audio was frustrating.
                        It seemed that one needed a seperate Bluetooth device to utilise handsfree, but then it wouldn't come through the car speakers, and it wouldn't mute the media.
                        I have found a possible solution though. STRIKE iK-1 BLUETOOTH HANDSFREE CAR ADAPTER KIT.
                        Apparently this thing connects to a head unit (in our case tablet/amplifier set-up) to do exactly what we're talking about. The drawback is that any phone must be paired to both the tablet AND the Strike ik-1 for this to work, and the tablet and phone must also use TabletTalk. But it seems it would provide exactly what we're after.

                        Thoughts anyone before I go shelling out my 'hard-earned' to experiment???

                          Based on that product being made in Australia I will take it that is the country you are from, which may make my solution a bit tougher for you to purchase however, I did go about this a different (similar but more affordable) way than using that device.

                          I purchased a Samsung HS3000 Bluetooth Headset and mounted it at the top of my headliner (where my sunglasses holder is between my map lights). Then I wired the Stereo output (3.5mm Headphone wire -> RCA Adapter) out from the BT Headset and into my MAIN input on my Equalizer. At the back of my EQ I used RCA Splitters to have both the Headset and the Tablet being input to the SAME MAIN input. I now have my phone paired with both the BT Headset AND my Tablet, so now when I get in the car I connect Tablet Talk and turn on the BT Headset and when an incoming call comes in, Tablet Talk pauses my Music and my phone routes the audio of the phone call through that BT Headset. Being that the headset and Tablet are on the SAME input in my EQ, I don't have to press anything on it to hear the phone call instead of my music. Then when the call ends Tablet Talk resumes my music, without me doing anything.

                          Oh and that Samsung BT Headset only costed me ~$32 USD, a lot cheaper than the device you posted. Your method seems like almost the same thing as mine just with a difference device in place of the Samsung BT Headset, so it should work, I just figured using this may save you some money, which who doesn't like to do that!

                            Okay that's a fantastic find. I didn't realise that TabletTalk would mute/pause the music whilst in the call and then automatically resume it. It would seem then that ANY bluetooth device with an output that could be connected to the Amp/EQ could be used and provide seamless use of the tablet. My next question then is, does anyone know of a Bluetooth Device that turns on/off with the cars ACC? This would preclude the driver from having to turn on the unit separately, and the mobile would pair automatically with both the Tablet AND the Bluetooth device.

                              Hmm, that would be nice, instead of me having to turn it on and off every time I get in/out of the car... I guess you could plug it in to power it like I did, then take it apart and pull the built in battery out, then leave the power switch to "On" and it should technically turn on/off with the car, no?
