Android Bluetooth Stack Development

Hey I know I'm more of a leech than a seed but I want to start an open discussion / brainstorm about the limited bluetooth capabilities within Android. Specifically on the HTC Dream (G1).
I don't have a strong grasp on Linux but I've been playing with different flavors since i was 13 (11 years). I don't have the knowledge or the support to even attempt this.
HOWEVER I do have a job and I do have the money (donation) to support anyone with the ability and the time.
That being said I would like to talk to anybody who would be Seriously interested in developing additional profiles for the bluetooth stack.
Anyone who has wanted to FTP over bluetooth or for me send my phonebook to my Lexus GS350 I would appreciate donations towards a common goal.
The $ would go to the developer or team. Of course after that it would have to be open source and free to the community.
I have not created a paypal or account for pooling donations but whoever is seriously interested contact me. I've got $300 (donation) to get you started (motivated)
Au Revoir,

i'm all about development and hard work, but with the release of blutooth 3.0, wouldn't it be better just to save the $ and put it towards the next android device that is compatible with bt3.0( which utilizes wifi for bt transfer...not to mention the improved battery life). what are your thoughts?

its not about the money. I'm using dudes cupcake rom whatever latest rom .92 and as far as i know there is no way to send my phone book to my Lexus when it prompts me to create a phonebook and because of this I can't use voice dial and nazi lexus basicly won't allow you to input anything while the car is in motion. the specs released on 1.5 only included stereo bluetooth theres still no push allowed or PBA

no, and sorry for the confusion. My point was that this android incarnation is lacking in bluetooth capabilities, and there has just been a new bluetooth technology released, not only having the wifi capability, but also all current profiles. I am sure that android will support this in the future with hardware in a new device, but for now, they are probably content with what they have, since it is an evolving technology.

Umm, Bluetooth 3.0 standard was just released. We're not going to be seeing any Bluetooth 3.0 devices for another few years, one at the minimum. Not to mention that the OP's Lexus would still require a transfer via Bluetooth 2.0 technology.

I would be content if an open phone with an open platform supported bluetooth features I could actually use.
I manually added one contact into the lexus and manually set the voice rec. and then attempted to call using 'dial by name' and it will only work if the dream is unlocked and awake.
BT 3.0 will be great. but I'd have to get a new phone and depending on the backward capabilities a new car too.
but that brings the question "how long do i have to wait for bt 3.0"
"how long do i have to wait for cupcake"
I was hoping with 1.5 they would expand on the BT stack and they did but not for anything I can use. whats funny is 2 years ago when I had Verizon and a Voyager I thought I was cool to have stereo bluetooth headphones to rock out too. and they want to market stereo bt as being a great new feature but its not new

This is an appropriate place to post issues with supported bt profiles already supported, but there is no guarantee that it will be addressed. i'm not speaking for anybody here, but me... butif it were my build, i probably wouldn't modify it for one make of car. There are other vehicles where this is working...am i right? i think so.
so far i think only broadcom has achieved and are planning to produce the new standard, but how long will it be till we see it??? my guess is 6mo- 1yr. Yes, stereo bluetooth is not a new thing, but i'm sure you can grasp the technology curve. "they" are only gonna release what they have to, in the time that will make sense to them, not the consumers. This
is a business, and will be treated as such. For how many years have we been scratching at the heels of EVERY advancement, just to PURCHASE it as soon as it comes around. edit...but to go along with you i was looking forward to file transfer myself, and it didn't happen.

what can i do on my car to verify the bluetooth version installed?, or bluetooth capabilities if you know what i mean
its a mazda 3 2010 sport
Thank you.

Your exactly right and thats what makes Android such a beautiful thing. Because we are longer governed by whatever corporate timeline 'they' decide. the timeline is to maximize profit. cupcake is marketed as a feature update to show dedication to their product and to their customer base but its not a dedication because they were forced to evolve it to make it compatiable with additonal hardware and minimize the media attention towards custom devleopment and end user modification. Google doesnt want to piss off Apple or HTC or T-mobile or Vodaphone ect because thats business.
Google doesnt care if you transfer over bt they dont care if you mod your phone. but when Apple says no mulitouch and vodaphone says No Bluetooth profiles they don't have much of a choice if they want Android to succeed.
and Thats why they made it open.
same with rooting your phone google had to fix it beacuse if they make it look easy they run into problems. T-mob or voda don't want you to teather your phone and use it as a modem and root allows this. so you must disable and discourage root and tell people its a security risk.
fcuk T-mobile and their G1 bs marketing. My phone is a Dream.
---btw the new radio gives me 3G in my house now wootwoot so i can actually talk on the phone with t-mobiles shi*ty service--- I only left Verizon because phones suck Donkey...Anyways..
its not just one car. go http://en.wikipedia.org/wiki/Bluetooth to see all supported profiles
there are profiles that all cars support. most likely PBA "phone book access"
I know when the Prius 1st came out I was like 16 or 17 lol and none of VZW phones could send phone book data to the Prius only because VZW policy with phone makers demanded they crimple BT profiles even on smart phones. so you couldn't FTP a mp3 and set it as ur ringtone you had to buy the ringtone for 2.99 or what i did back them I used Bitpim but you get the idea.

I would google some keywords and try and find a user forum for Mazda cars.
I know theres clublexus.com where I have learned a lot about my car.
for some Lexus (i know for sure the GS and LS models) you turn the car on, then hold down the INFO button while turning the Lights from OFF to ON four times. and the car enters a Service Diagnostic mode and you can view different settings and run diagnostics, clear error codes and rescan. I know theres a spot to view the bluetooth version and software version. You can adjust the Mic volume, send and recieve volume and adjust voice quality.
You really don't need to adjust your car (thats not what this post is about).
Depending on your car you can get updates from the dealer and you can find software mods online for some cars.
example; lexus had a override in the system menu to allow user input while the car was in motion. IN 07' that option was removed on all models so for my 07 Lexus i found a post from someone that had taken the Nav disc for the same model in 06 and he modded and issued a ISO for users burn to get that override feature back.

Bah! @ Bluetooth 3.0. Totally overhyped standard. Could be completely done with adhoc wifi and would be easier and more than 2x as fast.

[email protected]:
Yeah, it is... It's just a wifi coop mode, which requires both parties to have a wifi-radio free to use...
It's not really an optimization of bluetooth :/
Everyone else in here:
Well, i'm not sure you're gonna catch many devs in here (There doesn't seem to be any

Power management is much better in Bluetooth. Combining the two gives the best of both worlds. BT 3.0 will be able to connect, go into low power states and only turn on WiFi if a higher speed transfer is required.
BT 3.0 is more than just BT+WiFi anyway. The ability to have an Alternate Mac-Phy (AMP) like WiFi is one feature. There are other new features as well (like better quality of service). Also, an AMP could be a Ultra Wide Band (UWB) radio, with speeds much higher than WiFi with lower power consumption. The potential for 3.0 is really interesting.
But as others have stated in the thread, it will be a while before there are any implementations. We are just starting to see 2.1 devices in the market.

I know this is only my 2nd post, but I too am looking for better BT Stack. Dont get me wrong I love that I got back my stereo BT on my Pioneer Avic-D3 but unlike my Nokia N95 and my Tilt which lets me transfer my contacts to my Headunit.
Also another thing I miss is sending contact info from one phone to another!
Waiting for the time I can ditch my ipod and be apple-free LOL

I think a total update of the bluetooth would be cool. I think the 3.0 is a bit away but besides just a specific car profile i think it should be and all around compatible bluetooth. with all the devices and allow file transfer as well something that non g1 phones can already do. I think that alone will make it feel much better until until the newer technology is intergrated. That would probably lean me more to donating

I have two old Motorola RAZR's and they transfer data over BT, it is really surprising that the Dream falls short in this area.

I just miss the very basic file transfer (obex) to move images, mp3, contacts, etc. from device to device. I know I can set up an ftp or webserver to allow phone to phone access, but quite frankly we shouldn't have to use a work around for such a standard phone option. ALso, I like to bluetooth pictures from my phone right to the Kodak picture printer in Walmart and other stores. There is no way to install an FTP server or client on that machine (without some hacking).
I would donate if we had some devs on here taking up the task.

Personally, I'm not surprised that the Dream falls short in Bluetooth support. My experience with Bluetooth in Linux has been very unsatisfying. I don't know if that stems from the Blue Z stack, or if no one cares enough to do things properly. The last couple of times I upgraded Ubuntu or Kubuntu, Bluetooth was totally broken, and I had to figure out my own workarounds to get some of the functionality I needed.
What I would currently like to see is DUN support, so that my Tom Tom can access the internet. Very few BT phones don't have DUN, especially on T-Mobile. Makes me wonder why T-Mobile wanted to get the Tethering apps out of the marketplace. You can tether with almost every Bluetooth phone they sell!

Use HTC Touch Diamond 2 as a remote for a rc car

Hi everyone,
Okay, here is the idea. I have a HTC Touch Diamond 2 and I was thinking that it could be interesting to try to use it as a remote control to pilot a small car or plane (using the Bluetooth frequency).
I found several receivers in the 2.4 GHz frequency band, but I'm not sure whether it could work or not. Here are a few: link 1, link 2, link 3.
So the main questions are:
- Is it possible to program my HTC so that it sends information the receiver will 'understand'?
- Is there by any chance already an app that allows me to do just that (or something close to it that would need minor modifications)?
On top of this, I was also thinking of adding a camera on the car that would send back to my phone what it records. But this more than optional since it probably will make things much more complex... (I found transceivers such as this one and this one, but it looks like a lot of work to install and configure them).
Thank you for your answers and your help in advance!

Anyone to help me?

It won't work, sorry. Not with any store bought RC car. Your only chance is if you engineer the receiver yourself, including the circuitry that translates the radio signals into motor signals.

Thank you for your reply!
Ah, that's quite disappointing
But just to make sure, can you tell me exactly where the problem is? I mean is it a true hardware problem, in relation with the kind of signal that I can transmit with my phone (like a frequency incompatibility or something else)?
I was hoping it was possible to program my HTC to send the appropriate signal corresponding to what the receiver is expecting to get. Why couldn't it work?

Am I at least asking my question on the appropriate section of the forum, or is there another one that I should use rather than this one? Thx again.

Music dock for Android?

Hey all, I was wondering if there is something like a music dock for Android phones. Something like the Logitech Pure-Fi Anywhere 2 would look great. Something that has a remote control and communicates with the device (not just headphone jack in). If it works with iProducts then even better.
Suggestions?

If i am not mistaken a new mode was have to be incorporated into android as unlike the iphone that has a dock mode using its cable all the android devices either have mini usb or propriatary jacks that use the same usb specs in a different form factor!!
The best bet would be to use the standard audio jack but sell a bluetooth remote control to go with it, then using a modded open source music player and bluetooth drivers supplied by the dock maker do the functions you have suggested!!
I would buy one!!

Bluetooth remote hey? Haven't seen any around (that would work with android). I'd still prefer a dock like I described since I would then need only one remote control, not two.

yeah your way sounds the best, its just getting that feature added to Android as as ASOP so the phone would be able to take commands via usb as it seems it would need to be a system level command chain! so pluggin it in and seeing it popping up saying mass storage, pc suite, charge only and also have an Audio docking option would be the ultimate goal before the docks go into the design room!
Or maybe the dock is bluetooth 2.0 and all it does is hold the phone and charge it? that would take hardly any modification!! these are the ideas that need putting to companies like creative etc!! they should have no bother making models for the HTC ranges! and maybe samsung

No bluetooth please, sound quality over AD2P sucks.
A decent solution would be a standard 3,5mm-connected remote interface, just like on corded Nokia or Apple handsfree; luckily enough SGS's sound quality is decent.
A USB connector would simply be astounding, although quite difficult to implement: remember the iphone has a line out in its bottom connector so a dock is kinda straight-forward to make; going through USB either means rerouting the line out from the DAC (impossible to realize just with software) or creating a standardized driver to connect an external DAC. Read: nobody is gonna do it, as no big company is willing to go through the trouble of making something (very) hi-end only.
*Drools while dreaming of an USB attached DAC/amp*

Considering that most Android phones can connect in USB mode, there could be an external dock that plays the mp3s' on the phone. On the other hand, this makes your phone no different than a flash disk.
Shouldn't there be a protocol for docking this kind of devices? I think phone makers are really losing the game by not creating a protocol for wired music docking, the result is that there is a TON of peripheral for iProducts (from hifi to cars) but almost none for anything else. Crying shame.
In the end a 3.5mm would be the most realistic solution but still, i'd like some sort of remote control.

i would be quite happy with a cable that has a male 3.5mm on one end and a female apple dock connector on the other.
you wouldnt have problems then when you were round at a party and all they got is an ipod dock with no line in.
cant the enterprising chinese come up with a solution?
EDIT**on closer inspection i found that cablejive are doing something called a dock input cable. i would post a link but im not allowed
it may be what im looking for

Didnt seen anything abaut a dock...
However i got this product from Belkin and it works very cool for my intentions.
**cant post since im "new user" tho, google it: "BELKIN bluetooth music receiver F8Z492"
Its just tap 1 button and play the music via bluetooth (A2DP), very nice quality.

I suppose the above are both working solutions, though I don't really like the Dock input cable. I mean, you lose the ability of remote controlling your player and you would use that only with iPod / iPhone enabled hifi systems, which I find redundant (why buy such a hifi system if you have Android? Then again if you already have one, that changes things).

to be honest it wouldnt take much to develope the librarys for the controls through a usb cable, but with no ones builds being asop and a non general development tree with the xda scene as it is, it would be virtually impossible to the get this now very fragmented market of phones to have a standard for docks! heh i might even put this to someone I have consulted for in the US about bluetooth technologys to see what he thinks!

I think the idea would best apply to "personal hifi systems". Something like boom-boxes or even small audio systems. These could provide basic functionality through their standard lcd screen and remote control, but when you add a phone on, they'd have a really nice looking screen and new features (depending on the phone itself). Bluetooth can already music-pair with other devices but I think there are better prossiblities using USB (not to mention that your phone would be charging at the same time).
I think it's time for people to stop looking at docking as gimmicky and start developing docking methods that actually add to the user experience as well as functions.

When you think about how many media functions a modern smart phone has its crazy even samsung dont start shipping range specific docks for android devices!
I would love nothing more than my phone being on a dock over night charging! when i wake up to the alarm/custom song/internet radio station i press a button that keeps the music on then pops up todays appointments and meetings on my calendar! Then to top it off a text to speech engine reads out the headers from all my emails before cooking my breakfast and kissing me on the cheek goodbye

Unfortunately I think we may have missed Christmas (!!) but I believe there is something in the pipeline from one manufacturer that is developing Android docking solutions for later this year.

[Q] Using gps-500 with tablet?

I have a gps-500 (a usb based GPS receiver) from when my laptop worked and wondered if some guru out there found a way to make it useful with the tablet.
For the price, $19 or so to purchase the 'sensor', it would make the tablet become a cool GPS for any others where tethering is not an option.
(http: preceeds the line below, since I'm too new to post links)
//linux-tablet-pc.dhs.org/2010/12/13/gps-receiver-microsoft-pharos-gps-500-iii-gps-receiver/
googling "pharos gps-500 linux" turned up quite a few places of interest
I also wanted to thank the devs for the wonderful work they are doing to let us use with our newest toy.. i mean tool

i'm using a bt-1000x travel recorder, it's a bluetooth gps, i't working great, all i have to do is use a special program on the gtab so it knows about the gps, works perfectly with google maps

was wondering if you had gotten this going yet? I have a BU-353 usb gps receiver and haven't gotten it to work yet. also haven't found (so far) any threads in the Gtab forums talking about if usb gps work or not with the modified firmwares.

Nothing working for mine so far. I had looked at this,
wiki.navit-project.org/index.php/Navit_on_Android
it "works", as in 'it wont crash', no maps show though. I have not yet posted any questions or such to see if anyone knows a way to make the program take its input from my gps receiver. Though it may be as simple as linking the programs expected input device to /dev/USB (or whatever the proper syntax is)
The nasty thing is I had to get the Google Market working on the dev kits virtual device so I could use the virtual device to download a supplementary apk which was required by Navit (a text to speech apk) ...(the market via my tablet couldn't find it, or GPSTether either)
And found this as well, still no joy

I'm so new to all this android stuff, 3 weeks, but I'm having a wonderful time playing and experimenting
Regards and have fun,

Was there any more info on this? I just bought one of these GPS units and can't get it to work.

Android Bluetooth Driver

I was google'ing for anything about this bluetooth driver for android I have and came across this link :http://forum.xda-developers.com/showthread.php?t=585942
The OP has a pic of the exact app I have but they didn't have the apk file. Well I have it and wanted to post it somewhere someone might be able to fix it. Every time I try to run it says it has to activate over the internet but fails and closes.
Maybe someone can fix or bypass it.

I have the same problem .... and I can not connect the bluetooth mini keyboard .... my hd2 android [email protected] GRATEFUL help ...

that's an early version of the Teksoft "BlueInput" app.. it no longer works I reckon, the version has been bumped up in the meantime, and it now sells for 10€..
Hugely overpriced if you ask me, especially considering that the licence is only valid for 1 device (i.e one keyboard, if you have two like me you have to pay twice that), and the phone ID that is the base for the licence number generation changes as soon as you tweak one setting or two on your ROM.. And you only get 3 free resets of the registration number.
don't buy that crap, i've been hugely disappointed by the dev's attitude towards software licensing.
I ended up installing a CM7 on my SGS2, BT keyboards work pretty much "out of the box" on it without any 3rd party driver. but that's an interim measure, i'm currently trying to compile a whole new (and complete) BT stack for the SGS2, based on Bluez-4.96 (supposed to fully support the HID profile used for keyboards).

I was wondering the same thing.
