Bluetooth serial port? OBD2 device on android

Hi,
Since a few days im a proud owner of a HTC desire.
On this device i am trying to connect my bluetooth OBD2 car diagnose device.
Unfortunatly i cannot get it working.
What i did was search for the device in bluetooth settings, pair it with the phone (The bluetooth device says paired, but disconnected), and change the settings in the obd2 app to make sure it uses the device ( i tried torque and obd2 reader). This will result in the following bluetooth error :
1270932653682 **** OBD Comms thread starting ****
1270932653682 **** Connecting to OBD via bluetooth ****
1270932653686 **** Connecting to OBD via bluetooth (1) ****
1270932654262 *** EXCEPTION:Service discovery failed ***
Service discovery failed android.bluetooth.BluetoothSocket$SdpHelper.doSdp(BluetoothSocket.java:377)_ android.bluetooth.BluetoothSocket.connect(BluetoothSocket.java:201)_ org.prowl.torquefree.comms.OBD$CommsThread.run(OBD.java:305)_
The previous phone i had was a touch pro 2 running Windows mobile. I managed to use the diagnose device on this phone for a while without any issues.
What i am thinking is that i maybe miss out on a step on the android phone to get it working. This is because on my windows mobile phone i had to setup a serial port first. Could this be different in android, or am i doing something wrong?
Any help is welcome!

Anyone with ideas ?
Thanks alot!

do you need the software on the phone to run the obd2 connector? do they have that software available or is it just for data logging? the connection is there but there is no software calling for the data connection.
good luck. hopefully. the manufacturer developes or ports their software to Android

Yes you need to software to communicate with the obd2 bluetooth connector. You pair it with the phone, and then need to software to get the info.
There are currently 2 apps available, but they both fail to work. I thought it could maybe be a bug in android, but i can't seem to find any info about it.
I also expected i could have made a mistake while pairing the device to the phone, since i am only using android for a few weeks

it should be working, the only thing is that further down the debug the bluetooth stack blows up inside a native method

I'm itching to see what the UUIDs your bluetooth device advertises

Hey ! we have spoken through email
Im trying to see how i can get the UUID of the device. I tried it with my ubuntu laptop, but couldnt find it yet.
Im using the same bluetooth device as listed on the torque website, the one with the blue sticker on the side

I have bonded the adapter with my laptop. Then setup Serial port.
I did not manage to get the UUID yet, is the info below helpfull?

Yep thats fine on the bluetooth info, this is looking like a bug in androids handling of bluetooth, and it's a weird one at that.
Is your firmware a completley stock ROM for the phone? You haven't put a modified ROM onto it?

Well good to hear you at least know what is wrong.
My rom is a stock rom. This is the info from settings, software information :
Firmwareversion :
2.1-update1
Smallbandversion :

Software number :

Browserversion :

The phone's model number is HTC Desire A8181
Do you know what the bug consists of?
Thanks again !

Sorry, I haven't replied earlier, been busy for a few days.
It's looking very much like a bluetooth stack issue on the HTC Desire. Googling a reveals a couple more grumblings with the desires bluetooth stack but nothing concrete. Unfortunately I haven't got one of the devices directly to play with to verify my assumption, so fixing it is probably not going to happen (if I am able to work around the bug at all!).
Unfortunately I'll have to say you're out of luck /for the moment/, if one of my friends aquires one (or I can reproduce it on my Nexus one if/whenever Google/Brightpoint decide to deliver it!) then I will try to reproduce the fault and to get it to work for you (from my point of view I want this to work with as many devices/vehicles as possible!!)

Is there anything i can help you with? as i also really like to use this app.
If you provide me with things to check, gather or investigate i would be happy to do so!

Hi
Just to let you know I managed to sort a workaround out for torque with regards to the bluetooth problems and it is now connecting fine

The code was 1,2,3,4

I've been a android user since Sept '09 (G1/Dream) and now I recently got my X10.
I've had a Nokia 770,800, and now N810. I used a application called 'Carman' which would read a OBD2 Bluetooth unit which was connected in my car. I would simply plug it into the port under my steering wheel and it would show up easily on my Nokia. The software worked great.
There is code available, and the website for carman is: http://openbossa.indt.org/carman/
The bluetooth unit I got was this one: http://www.dealextreme.com/details.dx/sku.16921 (although mine is orange, got mine back in Dec '08)
It would be great to see this being ported over to Android. Hopefully this is helpful!

yeah i've been searching for awhile and apparently HTC broke the stock bluetooth stack with some kind of proprietary settings that makes most advanced functions not work (HID, SPP, etc) it appears if you use a rom thats not sense based (like cyanogenmod) then the profiles work

[Q] Cannot pair Nexus One to Windows 7

Hello, I hope someone will be able to help me...
Details: I have Nexus One, CM6.1 RC1 ROM, Clockwork Recovery [latest], app2ext on 16GB sd card. OS: Windows7 Ultimate 64bit
When I try to add Nexus to devices via BR radio Nexus and Windows 7 show different passkeys and therefore cannot be paired. This is so bizarre I even don't know where to start troubleshooting. Anyway I can successfully pair regular mobile (Sony Eriksson w880i) or conversely connect my Nexus to other devices such as headset, other mobiles, car.
Any suggestions?

If understand you right, you are saying that Windows passkey for bluetooth and your phone's passkey for bluetooth are different.
Now again I might not be understanding you fully.
Each device its obviously going to have a different passkey. If everything device on the planet using BT had the same passkey, what would be the point of the passkey in the first place? Type the windows passkey on your phone and type the phone passkey on windows. Or just use a USB cable.
If I didnt understand you correctly, I'm sorry.

This is not how it works. It ask if the passkey shown on the screen is the same one as on the other device. Yes or no question. I don't have a chance to type one. U c?

I attached a screenshot to explain.
Sometimes it does not ask for passkey and instead show error 0x80004005

Apple bluetooth keyboard

I can't seem to find a definite answer to this: Has anyone had an Apple bluetooth keyboard work with their g tablet? There's a laptop like case for the ipad that has a bluetooth keyboard that I would like to modify for the g tablet, but I'm not sure if the bluetooth keyboard that comes with it would work.
Thanks

I tried my friends ipad keyboard case but couldn't get it to connect to the g tab. Wish I knew how

Same here. I have an iPad (company issued) with the keyboard but I can't make it pair with the gTab. It sees the keyboard and asks for a code and I've tried 0000 and the classic 1234 and neither seems to allow a connection.
A while back when I was looking for something similar and found this.

At the time the seller claimed it would work on any bluetooth enabled device including Android devices even though he doesn't list it in his description.

I read that you can pick any code you want, then type it on the keyboard and hit "enter".

I tried that just to check but no dice. In order for me to type it on the keyboard it needs to be paired with the device. It doesn't pair so that didn't work. It was worth a shot though.

I tried using a seperate device and that didnt work either. Maybe some hack????
I tried typing on keyboard too and that didnt work... thought about it but no go.

I enter "0000" and it paired, but it shows up as paired, but not connected.

I tried..same result. Wouldn't pair

Hi all,
Sorry your having problems, what you need to do is get blueinput
its on the apps store, it works kind of.
Its been a few weeks since i set it up and used it,
From what I remember you have to install the apk into the system apk section on your tablet then just load the app and select the blueinput keyboard then it works.
it is limited and I lost connection a lot but as far as I could see it was the only way to get it to work.
Yes i used this with the mac keyboard, there is a topic on it somewhere in the g tab forums, and I believe it was a tutorial how to get it fully working.
If you guys cant find it I will do some digging or reinstall it and tell you all how to do it.

Yeah blueinput is what others are using, with that said most bluetooth things require a different program to get connected which sucks. They should have at least gotten bluetooth mouse and keyboard working in the Android OS by now...

actualy i found the post where all of the info is at.
http://forum.xda-developers.com/showthread.php?t=869747&page=4
also gunsjoe there seems to be a way to do this without blueinput.

I have not tryed prscott1's method my self but i think otheres have said it works.

[Q] Bluetooth keboard connection problems

I have a Galaxy note 8.0 (GT-N5110) running Jelly bean 4.1.2 and a problem I've hit is that I am trying to connect a bluetooth keyboard to it and I'm having problems.
When I connect the keyboard it pairs successfully but it won't connect to the keyboard to use it as input it only pairs successfully. I know it's not the keyboard because this is the second bluetooth keyboard I've gotten that supports my tablet and it just doesn't seem to connect.
I have other bluetooth devices that my tablet connects and in and outputs to fine. The keyboard connects fine with my mothers iPad my Glaxaly S4 both of which fun most up to date OS. I factory reset it when I first got the tablet and updated to latest OS so I can't imagine it's a bug in the operating system.
With this outline are there any solutions I haven't covered or tried?

Have you tried "External Keyboard Helper" - App?

I don't know. It worked for my chuwi V88 (very similar to pipo), but i used a custom-Rom. Just try it.

Sorry, i have no experiences with pipo-devices. I only know they are using the same cpu, as my chuwi (RK3188), an this one is really powerful!

Pairing a TomTom bluetooth remote to FRD-L04

Has anyone tried to do this?
My Honor 8 is Stock ROM, unlocked and rooted, and running Android 6.0.
I tried following the instructions on GorgiLabs from October 17, 2011, to no avail.
The instructions above are useful for Android 2.3 and below, except that someone tried with a rooted Stock ROM 4.3 by replacing a file in /data/misc/bluedroid. I tried that also, again, no joy.
I'd love to use my old TomTom remote while I'm driving. I believe once it is paired, I will be able to map the different keys. The problem is that Honor 8 recognized the device as a keyboard and asks me enter the pairing code, which of course I'm unable to enter on the TomTom Remote.
Any possible leads to force my Honor 8 to pair with this remote or anything similar that may lead me to find a solution would be greatly appreciated by me and all drivers I encounter on my daily commute.
Thanks!

I guess my question was hyper-specific. Let me try to be more general.
Has anyone tried to connect a Bluetooth device that requires a pairing code, but there is no way to type in the code from the device? Is there a work around?
Any, and I mean any clues to solve this puzzle would be very much appreciated.
