Hello all! I apologize if my question is in the wrong section.
I have a question about remote vehicle diagnostics, what software is better to use and is it possible to do it yourself?
Thanks for your help!
Hello!
Remote car diagnostics eliminates the need for a technician to be physically present to diagnose a problem with a vehicle. As far as I understand, it can be done with a hardware and software combination that connects a vehicle to a cellular network to obtain diagnostic data for further analysis.
Whether you can do the tracking yourself, I'm not sure, I think without the help of an experienced technician it can sometimes be difficult to correctly identify the problem. There are many nuances in the remote vehicle diagnostics process.

hi,
this is my first thread here, sorry for my bad english - but i'll try my best.
i want to connect my xda2 with the 22 pin-connector for mp3 in my car.
in your conectors-page is a note:
Audio needs to be capacitively coupled in, any DC bias seems to inhibit audio
i want to ask, what c is needed here? (how many farrad, what kind of C)?
please can you give me some tipps?
is there anyone who has built such a connection? is this a good way to connect the xda2 through the car-radio, or is it better to connect via audio-jack?
my opinion: i found it very uncomfortable to connect first the audio-connector (specially in the dark), and i would be very happy if it works through the 22-pin connector.
please please...gimme a tipp.
or did anyone connect the xda2 and car-stereo without couple-c?
c'mon please, a little answer and i'll be happy.
anyone must have finished a 22pol-connector by himself, or am i wrong?
ty
frustrated...(bad first experience)...
you may be asking too much of a technical question for the cuurent people who watch this board.. i get the impression that the xda-developers site started out with a lot of smart people reverse engineering and dismantling the devices, but its now become more of a software tech support site than a hardcore HTC guru site..
Hi there sorry to hear you have had a bad experience.
as stated xda-dev no longer is as good as it used to be.
i had a quick look at the diagram and from what i can see you should not need capacitors at all.
from what i can see if you connect up pins 3 and 4 to the necessary inputs on your stereo the sound is fine.
a problem i can see however is that to get output on these pins you need to attach pin 19 to ground with a 10k resistor...but this will also redirect the microphone so you wont be able to use it as a phone whilst you have it plugged in unless you also build in a microphone (mind you this should be pretty easy if you wish to do it).
hope that helps

Hi all
I need to develop an IT project for my HNC in Computing.
I'm a mature student with 5 years programming experience in VB. I've also got non-commercial experience with C#.
I was considering developing an application that would run on my QTEK 2020i.
I'm also a member of and MR2 owners club www.imoc.co.uk
I was thinking of combining these two interests and developing a diagnostic application.
Basically, as with most cars, the MR2 has a diagnostic port into which you can plug a diagnostic tool. Most of these tools simply run into a box with a single LED...the idea being that if there's a problem with your engine, the LED will blink and you are left to count those blinks and then look up that number of blinks to determine the error.
I was hoping to fabricate a connector from this diagnostic plug that I could connect to my QTEK 2020i. I would then read the pulses from the diagnostic port and interpret them programatically; presnenting the user of my application with an on-screen display of the erros and an option to print a report!
This could be expanded to encompass multiple vehicles...perhaps by providing the user with the ability to enter their own diganostic parameters etc.
Anyhow, I have no knowledge of developing on the .NET CE and even less when it comes to the potential uses of the various imputs on the QTEK.
Can anyone tell me if ANY of this sounds plausible?
Cheers
Wayne
This sounds a fun little project. Have you thought about using a modified Bluetooth GPS reciever to transmit the signal via bluetooth to your PDA which you could then check up apon when your running the engine on the move.
All you'd need to do is listen to the bluetooth com port and display the relavent data regarding your engine.
Just an idea to make it a wireless mod for a more impressive feature.
(Now I'm wondering if a QTEK 2020i could program an ECU for full engine customisation on the move.)
I saw a bluetooth car diagnostic system using a Microsoft smartphone at the Modaco meetup last year. Didn't get me excited, but did a full job at getting full diagnostics...

tbh I'd have no idea where to start with modding a Bluetooth receiver (don't yo umean transmitter though?).
Once I've got the application running it would be easy to expand later as I would hopefully develop it in a way that the different aspects of the application work very much "black box". I'd just have to write something to do the bluetooth side of things as an additional "black box" later on.
So, it sounds as though this is very possible then!
any idea if anyone on here knows enough about the numerous QTEK ports or how to access those via the .NET CE! :S

There is already a C# based OBDII diagnostic program out and contains all Source Code as well
OBDGauge 1.3 for PocketPC
http://www.qcontinuum.org/obdgauge/
I was coding my own version before until i found it, and decided not to reinvent the wheel
I used a XDAII Serial cable and connect it to the OBDII Port to my XDAII. Works perfectly, however, my Universal doesn't have a Serial Port, unless u get a Bluetooth version
i'm sorry if this question is vague.
I'm working on a app for work that needs to be kept classified until done if it can be done.
I was wondering if there is way to use the bluetooth function on the phone within an app. without having to root your phone.
it's hard to ask this question with out giving away the classified information.
http://developer.android.com/guide/topics/wireless/bluetooth.html
?
You can write code that sends and receives data over bluetooth if thats what youre asking. One example is handling the NMEA messages from a bluetooth GPS
do you think it would be possible to use a android phone as bluetooh headset?
Really depends on the phone and what you're connecting with. I'm not sure if a phone can receive A2DP connections, but it could be possible. Phones definitely can recive data connections over bluetooth, I just don't know enough about A2DP to know if the phone could work as a server for it. Someone else who knows more about A2DP maybe will know though.
It also could be possible to use something like SPP or RFCOMM.
Really, there isn't a good way to answer such a vague question.
sorry i have to keep it classified due to work, if it was a personal project i would give the full details of it.
Totally understandable I just wish I had a better answer for you.
thanks for your help i will keep researching looking the google information and etc
I think that if the Android libraries don't provide what you need (and I suspect they don't), then you are stuck, without root/SU.
I've developed an FM radio app that speaks to the FM chip via HCI, and spent a few weeks trying, but was unable to get raw HCI access except via existing command line utilities on the phone.

Hi all,
Was poking around in secure settings in launch activity and in the drop down menus it mentioned obd, and diagnostic activities. Curious to know if anyone has looked into that and whether or not that has anything to do with interfacing our car's OBD II system via some bluetooth hardware. OBD is a pretty standard "architecture", so velocity, fuel consumption, etc are easy to grab. Would be neat if car mode had some sort of obd functionality built into it (ie logging, fuel efficiency display, etc)

You didn't tell which model or firmware version you saw this on?
A screen shot would be good too.

Thank you for the details.
Note that you're posting in the wrong forum. This is an S5, not S4 forum. Notwithstanding that, I haven't seen the apparent Android hooks for automotive OBD documented or discussed on XDA before. Nor does a cursory search appear to pull any threads up about that.
There are OBD threads, but they invariably assume the use of a hardware OBD II chip (inexpensive versions exist). What you ran across appears to be an OEM tie in feature.
Here are a few existing OBD apps and projects:

I don't feel that I'm posting in the wrong forum as from my understanding (could be wrong tho) car mode was ported from s5 (along with UPSM, kids mode, baby monitor, etc) by tamirda. Thence, since more development must happen on the original device's (S5's) thread and the inherently increased awareness of said device's features and functions, it seemed only logical to post it in said forum. Furthermore, I too have searched XDA which only ever increased the need for me to create this post.
Now I am also aware of these apps and bluetooth/wired obd devices (in fact I have used many of them), it doesn't negate the fact that I noticed something that I have not seen documented. Anywhere. So, it is with the deepest confidence of entering an uncharted territory, that I had to ask if anyone had the slightest inkling of an answer somewhere on paper that perhaps (or not) the OEM is planning to implement (or unbenounced to us, has already implemented) obd interfacing into the galaxy car mode.
Again, as I stated in OP, it would be nice if car mode kept track of mileage, economy, distance travelled, obd logs, extra gauges, vehicle status monitoring....etc) as an extra built in feature. Thanks for your quick and kind response
Hi this is my first post here after it being recommended from another forum
I’ve recently purchased a android unit for a 2012 Range Rover evoque and the USB port is not working. It’s the only one and there is power, it’s able to charge devices but I cannot use a memory stick or my CarPlay adapter
I’ve attached some photos of the system information from factory settings and a photo of usb device test
If anybody has any ideas on how I can fix this is would be hugely appreciated!
If you need anymore information about the unit just ask
Anybody have any ideas at all?

Seems to be a hardware issue. You should get in contact with the seller to get this fixed.
I’ve tried contacting the seller and unfortunately they are not interested/don’t want to help
Then open a dispute and send the unit back.

The last option is to connect a small USB hub but I would be sending it back because who knows down the track what other issues may arise.
I put a small hub in the middle of my center console so that all the USB's can be inserted at anytime.
Sending it back/disputes/refunds etc are not a option. I’m stuck with the unit and I’d really like to find a way to fix it

So how to find a way to fix it if the data connection is broken in a forum?
This is no software issue. It´s a real hardware issue.
Sending this crap back is the only option, if you don´t want pay for a repair at a local specialist.
@sandpita
Sorry, but a USB hub does not make any sense if the USB does not work at all, just spending 5V, but no data. Didn´t you read his posting good enough?
I know from past experience with Linux/android boxes/libreelec/coreelec that 9 times out of ten a USB port that has 5v but no data is normally a software, firmware or kernel issue. I was told this and another forum would be the best place to get advice for these types of devices. Of course if sending it back was a option I wouldn’t even be here

My apologies, I didn't read it correctly and relax it was a simple error on my side.
Hey , i think i have a very similar version of this unit .
Mine is a new version for a 2012 RRS
I also had this issue ! , i resolved it by looking at the cable that goes into rear of the unit and one of the pins came unclipped. it happened after removing it so many times. Pushing it in fixed the issue.
Also, If this dont fix it. Enable developer mode . Looks for USB settings in there, theres an option in there that can change it from USB charging mode to data
Issues so far with mine
OEM interface didnt work - Update from seller
Overheating - Update from seller
Mic not working - Added a USB microphone
GPS signal weak - New GPS antenna
I am onto the last problem which is stopping me putting it in the car.
When ever i use Bluetooth Phone, I get a relay clicking sound from inside the unit . I then cant hear anything from the person on the other side. When i end the call it then clicks again and the stereo starts playing.
I also get the same clicking sound from Google Voice
Could you show me a pic of your phone app on your unit ? also.. Do you get what i mentioned above ?
Hi thanks for the reply ! I have very similar issues to yours!
- original car menus show a black screen with the digital version of the physical buttons it replaced Down the sides
-Reverse camera is also a black screen
-Usb not working as mentioned- I’ll try your cable fix though I’ve already enabled developer settings
-I haven’t had any overheating issues but I haven’t been on any journeys longer than a hour or so yet
Microphone is working ok and the Bluetooth audio and phone all work ok
I will add some photos tomorrow when I’m back with the car
My seller is useless and won’t help at all they simply ignore me, what update did they send you? My vehicle is a 2012 evoque dynamic lux
