Hi all,
i'm trying to pair my bluetooth OBD reader to my android headunit but seem to have a problem with the pass code. When pairing with my phone (as per the instructions) I am prompted to input the code (1234) but when pairing with the headunit it just connects and 'pairs' without any prompt which then causes a problem with the App associated with the reader.
Anyone come across something similar before?
Also is it perhaps worthwhile flashing my headunit with another rom? Mine uses the RK3188 so i'm guessing I need to be having a read of this thread

When you just pair it through BT it doesn't promp for code until you open torque app and set up car profile that's how I got mine to work

Yeah i'm not using the torque app its a bespoke OBD1 reader for Toyota engines, as soon as you connect to it with a phone etc it asks for the code but with this headunit it just instantly pairs without even asking and so when I open the app it just crashes as it hasn't been paired correctly.
ok so bumping this with some pictures as still have the problem.
Just to clarify the OBD reader is a bespoke item for Toyota engines and has a specific app for use with it with 100's of people are using on phones/tablets (including myself on LG G3).
instantly connects and pairs to headunit without the need to input passcode (unlike when pairing with my phone)
in the app for the obd reader you then select the reader from the list of devices, it should be indicated as OBD1READ like so
but instead reads
and the app insta crashes as a result of this

Yes, solved it this way.
Thank you.
Hi,
I've just purchased one of these head units for my car. I can connect my phone to it via Bluetooth just fine for calls and music, but I want to connect the head unit to my ODB2 bluetooth dongle so that I can create a Torque dashboard for it.
However, when I go to the general settings, Wifi is listed but Bluetooth is not. I've searched and searched but there is no way for me to connect the head unit to a Bluetooth device. I've tried various third party apps that claim they are able to enable Bluetooth and connect to devices, but they all just seem to hang when I try to enable Bluetooth. Tried a system reset too, but that Bluetooth option is still missing from the settings menu.
Please can anyone help?

I'm also interested in knowing this. Torque doesn't seem to detect my bluetooth ELM327 at all. I also attempted to connect a USB-based ELM327 module, and Torque seems to detect it, but it doesn't work beyond that, and the headunit gives me a low-power warning light.
Hi did you get anywhere with this I have the same problem can't get Bluetooth options to show
I have exactly the same problem. I'm running a PX5 unit from Witson. Custom built for a Koleos. MCU is not a standard MTC device. I have no bluetooth option available in the settings and the stock bluetooth app does not display any search option whatsoever. It seems that it broadcasts itself for other devices to detect it but you can't search for devices. Seems like they may be handling the bluetooth via the MCU directly and not via android which is strange because they openly claimed that this device was compatible with the OBD II dongle that I purchased. They even shipped it in the same package. Will keep looking and post if I find anything.
I had the same problem with a different Chinese head unit. Solved by buying a WiFi ELM327 dongle which connected fine with the head unit's built-in WiFi.
Update to my earlier post...I managed to get mine working over BT with the WITSON unit. In the end I had to disconnect my phone completely and reboot the unit. Then I found a search option on the dialer page. Searching found the OBD II module and I was able to pair with it. After I was paired with it I was able to add my phone again and both can run in parallel. I have not been able to test much but it seems like this continues to work until the unit goes into a deep sleep and shows the startup logo again. If that happens then I need to go through the learning process again. Meh...
Hi friend, just a question, in the dialer where did you find the search option I cant find it in my android radio??
If you have the swm 8802 you cannot connect to obd2 this requires bluetooth 4 and the 8802only support bluetooth 2
Always Connect ODB First
The ODB readers are a tad picky but they connect using the same menus as any other BT hardware (headset, speaker, etc). First, turn on the car ignition, do not start.
2. Make sure no other BT equipment is connected to the head unit or even on & near by.
Next, place the head unit in searching/Discovery mode and then & only then plug the ELM BT Module into the car ODB II Port. Most cars must be 96 & newer. 95 GM with for the plug but won't work. They're usually ODB 1.5, don't ask, your screwed.
Finally wait for the module to pop up and ask for the code, it's 1234 not 0000.
After your paired, THEN open Torque and let it connect. Don't start the vehicle till the car icon stops flashing.
You should be good to go from then on. If you ever have problems after that. Make sure the app is totally closed, force stop and then follow this procedure again.

Mine connected no problem. Did it just like I do on my phone. I just got mine too though. Could be an update maybe
the original question wasn't answered and I have that problem too. I don't have a Bluetooth discovery/search option anywhere. the small bluetooth-like icon on the main panel just changes the color of the leds.
so can't connect new phone. although Bluetooth seems to be working, since an older phone, already paired, is still working.
Following this as my head unit is same. Theres no blietooth menu/option but it connects to a phone.
Ive tried a third party bluetooth manager but all that says is bluetooth disabled by admin??
A fix
That happened to me trying to add and ODB2 bt dongle. I had to use the app for bluetooth linking provided by the head unit. When I purchased the unit, I changed the bluetooth discovery and pairing code to 0000. Well, changing it to 1234 allowed me to add the ODB dongle.
I saw it on a YouTube video, and well, it worked for me. (And no, no native bluetooth option, came disabled for my unit as you said)
Hope it works for you too.
same problem with me
Hi sir did you found solution for this problem. I also have this problem with my native bluetooth. when i turn open system setting bluetooth missing. i try to open using shotcut and found shotcut to turn on bluetooth but when i turn on. it do nothing.
I can play music, make call using bluetooth app provide from head unit. Problem is i cant use it with OBD2 . same with your statement this bluetooth only stream signal to other. this Head unit cannot find other bluetooth.
Kindly please assist me. did this head unit still have hope to turn on native bluetooth or not. I still search many post regarding this issue. But issue bluetooth like this not many discussion.

Change the pair code in the bluetooth custom app provided, to 1234 and try again.
I had this happen and I think I figured it out.... in factory settings there's an option to choose bluetooth connect automatically or with pin. I checked with pin and was able to pair. I think the options are reversed in the settings
I have the same problem i can't connect to the android 7.1 car head unit any more , the bluetooth setting is missing , the wifi settings appear but bluetooth doesn't appear any more
Anyone can help me to fix this issue please ?

I bought a bluetooth usb adapter and I can't select it on the system. I think this would be the way out, but we need to replace the driver inside android. Does anyone have any ideas?

I have a Teyes Spro with the same Bluetooth issues as most on this post describe. Did you find an answer to your usb adaptor to solve the Bluetooth problem? I was told to add a line to the config.txt file but cannot locate where to access that to add it.
Bought a Teyes Spro headunit and I have a problem with Bluetooth discovery on my obd II and tpms modules. Does anyone know what is in the "Developer" tab? It is password protected not accessible. The 168 factory access code does not work for it. Anyone know the password?
a. I am a normal user, mainly need to use Bluetooth for phone calls, GPS maps and spotify. I realized that the caller apps does not allow me to put short cuts (quick dials) to my favorite numbers. Is there any way I can do it?
b. It is rather useless to have a headunit if there is no internet connection. I have my HP for WiFi tethering, and also a WiFi dongle. Both doesn't work well because the head-unit can only detect WiFi upon restarting the system. I am not sure why, If I were to shut off my engine, start it up again. The system will not be able to detect WiFi.
c. My head-unit comes with Zlink (apple car-play). Okay, this is funny. I connected my iPhone to the head-unit, but upon connecting to zlink, the Bluetooth connection is cut.
d. I intend to get the ELM327 so that I can see those cool gauges. But can the head unit support both ELM 327 and my iPhone Bluetooth simultaneously.
e. Lastly, do I really need to root it to get it perform? I am not good in all these.
For advice pls.

Can someone give me some advise pls
Hi Tweakmax,
i have the same version as you have. i bought mine from Isudar and is currently installed in my skoda.
A)I'm also not verry happy with the dialer app. First of all, the app is called bluetooth and has a bluetooth icon while it is a dialer. The contacts showed up after 2 hours!! The default launcher does not support custom widget elements such as a shortcut to person. I suggest installing an other launcher.
b) I'm not expierencing this problem.
C) My usb ports don't work. How did you manage to install car play? I have android Auto. By the way. Why do you want to use car play if you have an android head unit?
D) I can confirm that the ELM327 is working. Make sure to unpair the OBD2 dongle from your phone. Then unplug/plug the obd2 adapter.
E) root is not required. You can install other launchers and install APK's.
Hi, i have problem connecting with the obd2 using the original bluetooth app, it says that pin or incorrect key. But when i downloaded an app off playstore which could allows me to use my own pin (1234) i can connect to the obd with no problems at all. but when i open torque or obdlink app it tries to connect again using the original BT app which will then have the incorrect pin or passcode. My question here is how can i change my bluetooth default pin from 0000 to 1234? I'm using an android 7.0 headunit.,
