Bluetooth Stack Protocols - Android Q&A, Help & Troubleshooting

Hi Everyone, I'm new here - just made an account because I cannot figure this problem out. I just started playing around with Xposed and I LOVE it by the way! but unfortunately that's not why I'm here. I have a Headrush bluetooth headset, it's great, has a built in mic, a2dp & works for calls even on a old ipod touch 4th gen for some reason though, my Lenovo a-5500f a8 ideatab running android 4.4.2 won't read the mic, I only have the media option, no call option.
I don't know what to do. there's like nothing at all on this, I read ONE forum that someone was experiencing my problem, and the only answer was that it's most likely because it's a WiFi tablet & wasn't meant to make phone calls on. I love my tablet & my headphones & would really be blown away if I could find a solution to this. I'm good with Linux & Windows, just learning Android stuff & it's really similar to Linux so it's not too far off, but I'm so clueless on this..
So an overview: my tablet won't detect the mic/phone call protocol for this headset, the headset works 100% on all other devices except for my new tablet.. I also have a few USB OTG's, is it possible I could perhaps run another bluetooth through a OTG? SixAxis works great, I can connect a controller, but not this mic..
any brainstorming to this helps, thank you.

[Q] Use phone as bluetooth headset for tablet?

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?
Isn't that like call forwarding or something?
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
yes!
Im looking thos for months my friend. But no one seems to know anything. We are talkin for clever and serius programming so it is not so easy to find sonething.
Profile
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 am seekung solution too.
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.
looking for the same here :-(
I want to buy a cheap tablet to leave in the car and use as a gps.
I'd like it to being able to be connected to my phone and work as a bluetooth hands free of sorts.
anyone has 2 android devices to try and connected and see what happens?
Me too - so i'm posting here to show that there is really demand for solution

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.
Why should it take people away from carriers? Me want to use my communicator as phone №2, so i could not take from my pocket the first one.

Because you could Google Voice, Skype, etc for a lot cheaper than a carrier.
same same, would be great solution to using tab as a phone
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.

Bluetooth Remote To Control An Android Phone

Hello, i've done a quick search on the forum here for what i'm looking for but all the posts are old and everyone seemed completely clueless at the time so maybe someone will have an answer now.
I have an LG Ally which is running Android 2.22 if I recall correctly. I currently have a setup so that I plug my phone into my stereo through AUX so I can use my phone to play music, and as a GPS when needed. I use the Music system that's built into android phone, but when i'm driving it's very hard to change the songs and still drive. I know they make bluetooth headphone that allow you to pause, skip, etc so there must be a bluetooth remote control that I can pair to my phone so I don't have to take my eyes off the road in order to change a song.
To make this clear, I am NOT looking for an app, nor am I trying to turn my phone into a remote control. I can't stress this enough, because a lot of posts I read while looking into this a lot of people where getting confused and thinking the person wanted to use their phone as a remote and this is not the case.
I would greatly appreciate some help finding something that would work, since i've not seemed to be able to find anything.
Sony Liveview
Check out the Sony Liveview to use as a bluetooth remote for you android based phones.
I would post a link but since i am a new member it will not let me so just google Sony liveview
Sony Smartwatch
Looks like the Sony Liveview is the older version so may want to look at the newer Sony SmartWatch
Maybe a Bluetooth game controller? Probably still need a helper app.
Not yet
I'm looking for the same exact thing, looks like it is such a small market that there are no products to suit the need.
There is a remote called Satechi BT Media remote that is compatible with iPhones.
If it works like like a Apple Bluetooth Keyboard, media functions should work with Galaxy Note, but I don't know about LG. Every company use different Bluetooth stack.

So i know this thread is a little old and i realize this doesnt directly help the OP, but could an IR remote, plugged into a USB host like a moto dock or one of those cables that enables the host command through the mini usb port possibly work? I suppose youd still need some sort of software to control the function...
I was thinking about this the other day when i had my phone attached hdmi to the tv, watching netflix. Once the episode was over, id have to get up and pick something else. A remote or a bt mouse might be a decent solution, but a mouse isnt very sexy as youd have to move around and click, as opposed to just using a directional pad or an arrow key.

I was looking for exactly the same thing, for the same purpose.
I wasn't aware of the bluetooth HID protocol until now and hence I was thinking about a different solution:
I thought about using a bluetooth headset for media control as these often include all the media control buttons.
However I only wanted to use the media buttons of the bluetooth headset while I was playing music through the headphone jack in my car.
Therefore I was seeking for a solution to connect the bluetooth headset in a way that its buttons can be used for media control but no music would be streamed to the headset or could be muted.
I think it's possible but some android hacking might be involved.
But that's a thing of the past with this new Satechi Bluetooth Remote, the amazon sales description states that Android devices are supported as long as they support Bluetooth HID. The customer review section also includes a guy who succesfully paired the Satechi with his Galaxy III.
The Satechi was introduced a couple of months ago so maybe other manufacturers will introduce similar and cheaper devices.
If your Android OS supports Bluetooth HID you can also use some Bluetooth HID devices which are advertised to work with iOS only (ie Apple Bluetooth Keyboard).

So this is a pretty old thread but Motorola has a product called the RZ100 which should fit the bill nicely. I use it for my GS3 (I travel quite a bit, so gs3 + HDMI out adapter + this remote = bliss) and it works without issues. The only thing I would like is an app that allows remapping the buttons on it (Ahem Android developpers...)

Thank you so much.
I'm using my Sensation with a Harman Kardon Go+Play and therefore had the same problem as OP.
I read your post and realized that I already own a Logilink BT0019 for other purposes.
I paired it and voilá, the music plays via the Harman Kardon, but the BT0019 media buttons still work.
Only Play/Pause and Next/Previous Song though because the sound level Buttons only change the Headsets volume which means that I do now need two remotes (the BT0019 +the provided Harman Kardon Remote for volume control.) but okay, cool.
I got the BT0019 for 22€, so it's a decently low priced solution too, even if I would not need the Headset for other purposes.
I know it's not bluetooth but the Mele F10 air mouse can do the trick via USB OTG.
I'm looking for a similar solution to control the media playing on an Android tablet for my daughter while on road trips. We have a Nexus 10 currently and will probably be getting a Nexus 7/Kindle Fire HD/Nook HD+ soley for her uses. Are there any android apps that might also achieve this using bluetooth? If I could control the media on the tablet using my Galaxy Nexus phone, that would be even better.
I succesfully managed to get what the OP asked for with an old TomTom bluetooth remote like this one (www ebay com/itm/331084156246) thanks to the informations provided by Norvan Gorgi at norvangorgi blogspot it/2011/10/using-tomtom-bluetooth-remote-with.html (insert dots as required ), and it worked brilliantly with both my SGS3 and my first gen Galaxy Note.
Basically, the remote is recognized as an external keyboard, so all you need is to remap its keys (the tomtom remote has 10 buttons) according to your needs, as per the instruction provided by Norvan in his blog.
Thing is, this stopped working when I installed CyanogenMod 10.2 on both my mobiles, appearently because android 4.3 now does not recognizes the remote as a keyboard anymore, but rather as an 'input device', ie with a nice 'joystick' icon next to it (and my own keyboard definition files won't work anymore).
Anyway, once paired with a 4.3 device the four directional keys and the central 'ok' one will sitll work, so it might still prove useful for someone, even if it does not have proper 'direct' media functions as it would have when set up as a keyboard.
Satechi Remote Control
I recently purchased the Satechi remote control because even though it says its specifically made for iOS, people in the reviews said it works on android and also because it works on 3rd party applications like spotify.
I have two Samsung devices, my phone which is Samsung Galaxy Note II and a Samsung Galaxy Player 4.2 which is just used to download my spotify playlist for the car. since the Galaxy Player 4.2 only has 512mb of ram its really annoying when i want to change song, very slow and I realised I pay a lot of attention to the device while driving and that isnt good!
so I bought the remote thinking it would help. now the problem is it doesnt connect to android devices because it requires bluetooth HID, according to a few posts found on this website and a few others, I downloaded bluetooth keyboard easy connect and on my phone it worked fine. however on my galaxy player it didnt work. it just keeps TRYING to connect, the device is running 2.3.6.
my question is, is there any other application i can use or anything I can do to use this remote on my mp3 player?
I realize this thread is very old but I found this thread searching for the exact same thing. I have not ordered this yet, but the Amazon reviews seem to suggest this item is exactly what I have been looking for!
Amazon link
Any current suggestions?
Do remotes just work as a HID keyboard or keyboard-mouse combo?

[Q] Multipoint bluetooth enabled phones

Hi Everyone,
Just to ask this question regarding Bluetooth functions on phones mostly on android. Has anyone knows an android phone which has a functional multi-point Bluetooth capability?
As i know only headsets can do multi-point to connect multiple phones at the same time, but not i heard of on phones.
This has been brought into asking since i was unable to connect on both bluetooth (blueant q1) headset and my live-view. It's only connecting on one device and then the other one will be disconnected.
----------
Knowing that this could use more power if this feature has been created, but can be made to be disabled as part of power saving settings.
I hope someone from the dev team can take a look at this functionality as this can be a great feature if enabled on android phones.
This could also mean modifying the bluetooth stack for this to enabled, but it seems to be a worthy one to be tried.
Thanks!
Hmmm.... seems no one is interested =(

[Q] HOX+ Bluetooth Phone issues

I have my HOX+ connected to the car via bluetooth. The music streams brilliantly. No issues there at all.
What I do have major issues is with Phone calls. Making outgoing calls is impossible it refuses to conenct to the bluetooth speaker even if you manually select the option, it just goes to internal speaker. If you select external speaker it goes ok but just wont connect to the car sound system at all.
In comming calls are iffy. Some times they pipe through the speaker but not all the time.
I know there are issues with HTC and bluetooth in general just looking for some ideas on how to try and fix the issue.
I have viper rom and elite kernel.
I was even thinking about buying this to see if it would help!
HTCs bluetooth stack has known issues with certain kinds of HSP devices.
The problem is that since the BT stack is propertary and closed source
it is hardly possible to change anything there compared to AOSP roms
where this is open source
So even if I guess you wont like the idea I can only suggest that
you try an AOSP rom if this is really important for you.
There is still not a 100% guarantee but chances are better that it works
About which kind of car BT device are we actually talking?
Even with the AOSP BT stack there are certain devices that have problems
espcially some kind of car manufature propertary solutions.
I use a Kenwood BT capable receiver and it works without problems
The device you linked may not help you because from the description
this is only for A2DP which doesnt include BT phone audio (HSP profile)
...
- this dongle is compatible with all devices with BT A2DP profile
...
Hmm ok so it sounds like the dongle shouldn't work as expected then ok! Just dont want to spend nearly £50 and find it doesn't work any better.
I have a Kia Pro Cee'd 2 with standard inbuilt car stero / bluetooth. I think it is the fact that it works sometimes bothers me more than if it didnt work at all!
I did try osap for a bit and had similar problems but will try again and see if I can get a good connection!
In the car I have buetooth connection, usb charging port and aux connection that is compatable with iphones. I actually get an iphone connection cable with the car!
Most of the bluetooth boxes I have seen only seem to have A2DP and AVRCP
connection profiles so I dont think these would work either.

well then this seems one of those sh.. devices
if you already have tried a recent 4.2.2 AOSP rom and it failed
then it prolly will still not work
Allthough there has been a patch in bluedroid lately regarding connection issues

[Q] Road Veles Android car stereo add bluetooth support?

Hello all,
I'm after a little bit of guidance on how I might add Bluetooth support to an Android powered Car stereo. It is a "Road Veles" single DIN WinCE and Android device with a 7" flip out screen. The reason I bought this stereo is to run an app by the name of MSDroid. This app was to connect to my vehicle's engine management system via Bluetooth.
Can't post links yet, easy search on Google for Road Veles, look for hit on Chinavasion
The specs say it has Bluetooth, but having tested the device out on the work bench what the specs don't say is that the bluetooth is only accessible for handsfree from WinCE, there is no bluetooth for Android. WiFi via USB dongle works great. I have purchased but not yet received a combined WiFi and Bluetooth dongle. I would very much like to have this combined dongle work with the device. The Bluetooth control is not visible under WiFi control inside settings like it is in my Android phone.
Can anybody point me in the direction of where to start with this? Can I root the device and mod to add bluetooth? Is there another ROM I could run? I have done a lot of searching but can't see much at all out in internet land on this stereo!
Any help greatly appreciated! Thanks in advance,
Arran
Hi, I'm not sure how these sort of things usually work, what sort of dollar value would usually be associated with making a some tweaks to an Android build? ...
Hi again, still looking into this. Any ideas how to tweak the Android 4.0.4 OS to make bluetooth appear inside the settings menu?
