Dear XDA folks,
a bit of a story about what the problem is exactly, and how I want to fix it:
I'm a happy owner of an HTC desire with froyo on it, which works like a charm.
There's one small problem though, my car stereo seems to be a bit picky when connecting.
My bluetooth is on, I start the car, and the phone tells me it has connected to a headset, the stereo tells me nothing is connected.
Same happens with the A2DP function, phone says it is connected, stereo doesn't detect it.
After a bit of messing around with it, I found a way to work around this, after connecting, disable and enable the bluetooth profiles (called media and handsfree in android) once, and they both work like a charm.
----
What I want to do, is make an app which checks if the device is connected to the stereo (which shouldn't be much of a problem), and then switch both of the audio profiles off for a moment (one at a time) and then back on.
Problem is, how do I switch them from my app? I've been looking at the documentation for hours, but I can't seem to find out.
The bluetoothchat sample is a great start to build a BT program I think, but I'm pretty much stuck here.
Is there someone who can point me in the right direction?
Thanks in advance
Nobody? I succeeded with making an app that displays the paired devices (after a bit of borowing from the BTchat sample), so that pointed me in the right direction.
Still, I'm stuck with the problem of switching the profiles/services on and off, and I'm sure one of you can help me
Thanks
Hey I'm no expert but you may want to check out the app called tasker in the market, you could look into the app's codes cause from what I experienced, I see a state there that says 'if bluetooth connected...' Then you can add an event to trigger after that.it's an awesome automater app. Base the codes from there.

Great thanks for the idea, will try that right away.
Will let you know how it turned out.
-edit-
DARN can't find options to enable/disable a2dp and handsfree in tasker, maybe I'm missing it, but so far I don't think it is there.
Thanks for the suggestion though
Help?! Can't believe noone knows how to do this?
Heeeeeeelp! Still stuck with it

Heres how I do it. Im running dexter 1.3 mod. You have to install the bluetooth fix. Put you a7 in discovery mode and you gps into discovery mode . Scan for your gps once found pair it with the a7. It should come up and say paired but not connected and thats normal.
Download bluetooth pgs provider from the market and run it. It will ask you to choose your gps. Tap on your gps when you see it. after that you should see a bar that says start tap on that. Now you should see stats at the bottom of the screen from your gps. Now you can run your gps program and it should work mine does. I use copilot live. I also use it on my phone. After I install it on the a7 I had to copy my copilot directory from my phone to the a7 to make it work. There are other bluetooth programs on the market that do the same as bluetooth provider If that doesnt work you could try some of the others
hope that helps

I am hitting a dead end. I have tried both Dex's 1.3 mod with the bluetooth fix as well as the 1.4 mod with the same results. In either case, when I go to the market, the Blue GPS app as well as many others don't show up in searches when I try to get them (for example, when I search for meowsbox I only see 3 apps including the "Bluetooth GPS License" but not the GPS app itself). I can see them in my PC browser but not via the market App and in my browser they say they are not compatible with my device. I was able to download Blue GPS manually from source_forge by accepting non-certified apps but that didn't work either (connection errors).
For reference, I see the following in "About Device":
Model Number: A7-040; Firmware Version: 2.2; Kernel version: 2.6.32.9 [email protected] #1; Serial number 2496430001227; Build Number: Dexter's ElocityA7 Mod v1.41; EC version: 0.14;
Also, when I hit the market, I see the following:
Maker:Compal; Model:A7-040; Carrier:T-Mobile;
Any ideas?

this is the only way, and it works.. i have used a bT gps with it..
remember as mentioned to enable "mock location" in settings -> development
Can't find the Bluetooth fix for Dextermod 1.3 does anyone have a copy?
I purchased a GSat Bluetooth GPS receiver and want to use it but all of a sudden I can't enable bluetooth. I'm running 1.3 without any patches and I used to at least have the ability to turn on the bluetooth and pair up a headset. Now, in settings, I can't even get bluetooth enabled (I have WiFi just fine). I was looking for the bluetooth patch that was created for Dexter's 1.3 mod, but can't find it. Does anyone know where I can locate that patch?
I know that I could update to 1.4 (plus patches) but I've been spooked by some of the problems reported, and everything else is working well.
Update: OK, I found it at Post#690 on the Android Dev/Elocitymod thread. I hope it works!
if i recall the right file from examining dexters rom, he replaced either the settings or contacts apk that originally had bluetooth settings option from elocity w one that does not have those bluetooth settings, at least in the 1.41 rom. so upgrading will not help.

Bestialbub, if you have any advice for me I would really appreciate it. Your wife is so lucky to have you to help her... my husband is wonderful but l'm the techie of the family!!!
i might have the answer for that one;
1
download and install "anycut" from the market. its a utility application for making convenient shortcuts to important activities and menus in programs.
2
open anycut from your applications menu.
3
choose "new shortcut"
4
choose "activity"
5
scroll down to where i hope you see "Bluetooth settings"
you should now have a shortcut on the desktop labeled "Bluetooth settings". see if that gets you to what you need. it didn't work on my cm6 froyo rom for my x10 phone, and i don't have a tablet in my hands at the moment. i just got a force close error. i should think if the bluetooth app (it is an apk) is working right, it should open that menu, even though you may not find it elsewhere. sorry if it doesn't work.
EDIT; otherwise, if that doesn't work, using the same solution you may find one of the many "Settings" listings further down the activities list could be a bluetooth menu entry as well. they don't list the subnames sometimes for multiple activities/menu's in 1 program. you may also find some of these activities/shortcuts causes your tablet to reboot.

1. i did not remove bluetooth ... why would i do such thing..
2. previous roms had firmware bluetooth problems not "settings" in android.. different story.. different problem..
when its said "bluetooth fix", it means bluetooth boot.img fix, not anything else.. i would not recommend ideas, when you can actually just open and check yourself... and you're not using so why start advising on the firmware you havent seen.. your advise can be easily misunderstood, and you cannot see the problem, as you start directing in wrong direction, which lead to total confusion, which i see now.... why use shortcuts when settings offer a "bluetooth" option like all android would...
@dexter_nlb; i never falsely represent my suggestions as definitive solutions; just possibilities as workaround for a device i didn't have in my hands at the moment.
and for the record, *i* tried both suggested solutions, and yes, i verified the bluetooth settings shortcut i suggested (which could be a convenience for some to have direct access to from the homescreen) worked, as well as yours. i made the silly assumption someone would have checked the settings menu before asking.
@okantomi; under Wireless in the Settings menu in the newest elocity firmware, i cant say for elocitymod version youre running.
sorry dex couldn't CLEARLY answer this before chewing me out. @dexter_nlb; did you try my suggestion before snapping?
i wasn't making things up about your contacts.apk either;
Code:
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
permissions not listed in the contacts.apk you provided that are listed in the factory apk. suggestive that the contacts.apk provided in elocitymod could be lacking some bluetooth functionality OR accessibility to such settings, at the least in the contacts.apk; a system application in your rom.
i'm pretty sure users are permitted to answer questions on xda without your permission, even if they do relate to your rom. wouldn't they be posting directly to your rom thread if they thought you were the only one with all the answers?
and i'm not suggesting you would intentionally remove functionality in your rom; but your rom is a work in progress, just like all roms. i'm sure with room for improvement, and those improvements are generally made with feedback and insight from other users.
good luck with your rom developmemt if this is how you respond when other users try to help each other online, out of your thread nonetheless, on a forum thats says "xda", not "dexter's". you should be taking these opportunities to learn from other people that are willing to help you, instead of assuming you have all the answers. i only quote what other users have been freely pm'ing and emailing me in private, after you've clearly given this impression to other users, and not for the first time.
EDIT: @dexter_nlb; i will have my own a7 by next week. you can rest a little sounder knowing i won't be suggesting untested solutions in the near future. sorry for the scare.
bluetooth access is if the framework require that in combination with a headset that has speech support or similar, but direct related its not.
Contacts and Bluetooth works independently.. and some rights failing during bootup can be ignored, and yes, contacts and calendar is "motorola" design for mobiles, so bluetooth makes less sense here, and the access is not important.
people using BT gps units mostly fail with it, as they think they should have it in "connected" state when they use the bluegps4droid app, but no, just have it paired is ok.. and mock locations enabled in this case under development, but all info possible to find when looking for bluegps4droid..
my previous problem with bt, was firmware flashing in previous releases not happening for all ppl. 1.41 do not have the problem.
the "problems" reported on 1.41 is sdcard related, that did not exist on 1.3 or previous as it were not at all found in android, but only as mount in filesystem. now its fully supported but with some tweaks to work with.
I installed Dexter's Bluetooth Fix for version 1.3 and it worked...I got my bluetooth back. Now I'm trying to get my GPS receiver to connect again -it did so for a while last night and won't connect again since I rebooted. However, I'm sure that's an issue with the hardware I'm using and will keep working on it.
Thanks to everyone who is working on making this tablet work better. I have learned a lot from all of the discussions and explanations. It is very appreciated.
I had an old "Palm" branded Garmin bluetooth GPS receiver laying around; so, I decided to give this a try with my A7. Pairs with bluetooth fine. Connects with Bluegps4droid. GPS stats seems to report the correct lattitude and longitude, but Google navigation does not work at all. I own copilot; so, maybe I'll try that later.
I can't post this in development because I an still a nobody ...
Would it be possible to add in rfcomm for Bluetooth SPP serial port? The Nook would make a great tablet for telescope mount control over BT. You can't do it with the iPad due to the security around the BT stacks. It would also allow NEMA GPS modules to be read for different applications.
I'm running CM7 7.0.2 and this isn't yet available.
Just a dream?
Not sure if this is what you're talking about, but you can send the GPS data to the Nook form a GPS device like a Cell phone or GPS receiver. I use a stand alone GPS receiver and sometimes my Droid cell phone to send my location to the Nook to use CoPilot and Google Maps on the Nook. That's at least half of what you're talking about right?

Hmm, you got me pondering...
I got out my trusty Garmin GPS 10 and I can pair but it's not connected. That could be for a couple of reasons (the Nook only connects on demand maybe.) But if what you are saying is correct, maybe it does support SPP since it uses a comm port for the GPS.
But, when I connected from my notebook and checked the services, SPP wasn't one of them (just OPEX and AD2P.) I will keep playing but I half expect that part of the SPP stack requirements are missing.
On the plus side, if the GPS will work too, that is a second plus since it's nice to be able to ask the GPS for the specific time and location during the telescope setup (it matters.)
I'll look for an app in the Market that might read an external GPS devices and show the location. I notice most apps are for reading the phone GPS (which we don't have.)
Thanks!
Android does not support SPP, but there are multiple apps in the market which do, Bluetooth GPS Provider is the one which I prefer as it works very well and just works no matter what.
Thanks folks,
I fired up the Garmin GPS 10 and it works using Bluetooth GPS. That means an application can add in the SPP. That is perfect and gives us hope!
I really appreciate the responses!

Yes, apps can directly talk with a Blutooth GPS. There are a handful which do this, or again, Bluetooth GPS Provider will provide the BT GPS to every app that asks for GPS.
This isn't only about GPS. GPS is just one aspect. I want to communicate with any serial device over BT. My understanding from reading it that rfcomm and the applications can supply that function.
What I did notice last night is that even without an application that supplies rfcomm, the Nook would still discover the devices unlike the iPad. I could pair to pretty much anything I wanted but it wouldn't connect. That's normal from my perspective.
At least I know it can be made to work.

Well, the XOOM does at least. Not sure whether it was Motorola's or Google's doing though. I use a Bluetooth to Serial adapter from Roving Networks quite successfully with it. I'm unaware of any other devices that do it.
I agree that native Android doesn't support SPP but the rfcomm library does and if it's linked into the application, SPP works.
Now if I can only find a way to use VNC to control my PPC from the Nook without going through a remote server (maybe via adhoc or BT ...)
Any device at API level 5 (2.0) or above may support BluetoothSocket, RFCOMM and therefore SPP unless the OEM did something to screw it up.
I was wondering how many have experience with the Garmifone? My G1 is dying a slow death plus I am looking for a better GPS receiver that I can connect to the A500 to use aviation navigation apps.
What are some thoughts here? Could this kill 2 birds with one stone?
I have heard from a buddy that he did not like it, but I have not had any experience with it.
NOt sure if teather GPS needs to have root acess but that will share your android phones GPS with the iconia.
if your also looking there are bluetooth GPS recievers, I have yet to use one, they do pair with android phones not sure about tablets
Thanks for the feedback Brian.
I have been looking at the Bluetooth GPS receivers made by Globalsat and talking with the developer of the Naviator App. He has been using a Bluetooth receiver paired with his tablet I believe and it seems to be working. Since I need to upgrade my G1 anyway, and don't really care about all the social networking bells and whistles that come with a lot of modern phones, I was looking at the Garminfone for it's navigational abilities.

Good looking phone. Do you know how well the GPS signal locks in it?
mine has been fine always gets a lock
I've had one for over a year now. It works fine. I don't know anything about linking its GPS function with another device. I tried to find a way to use it as a GPS receiver for a PC application, but could not find a way to do that.
I use the GPS in my Nexus One for my A500, shared via bluetooth. It works 100% beautifully, since it can lock down almost instantly and tracks more accurately than this thing can. I use Sygic's latest release as my navigation app, the only problem it has is that the top part of the interface is cut off (it doesn't use the new HC full-screen mode, yet), so the signs that come up are cut off.
Hi all, the Pioneer SPH-8TAB-BT is brand new and decided to open a topic about it.
First issue I have that there is no call-out button in the software, while if I am dialing a number on my phone, there is a screen that shows who I am calling.
Second, is there any other FM app that could work. The stock one is too ugly.
I found out voice dialing works if you update PSS in the Google Play Store, but there is no Bluetooth dialer app yet

Would be better to ask in a Pioneer forum.
The unit you got is too seldom at XDA. Seems that this is a real tablet just with a connector to the head unit.
No one knows what´s in there.

Seriously??? You are kidding us, are you?
A car device without phone call possibility???
I would send this bull**** back wherever it comes from.... sorry, but this is not acceptable.
Just mounting a tablet on some mysterious radio without necessary functionality is not ready for sale.
OMG...
I agree, but other than that the device is great.
Anybody here who already has the device?
Update
I have the same model Pioneer has brougt an update on their site go to pioneer and go to software and type you're model nr to download the file unpack it to a usb drive so now you have the Cal function you have to update the pioneer sync app on the tablet and need a usb stick wit the download file plugged in to the system
