SWM8802 Bluetooth settings missing

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.

Hello there,
My problem is some how different. My hu use the bluethoot to find the obd2 adapter but there is no dedicated pair button. I can pair my phone for calls and music but connecting from phone to hu.
My unit is a 8227l from seicane.
Has anyone any solution? Thank you!

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?

Display 'Torque Pro' directly to head unit without relaying through mobile device

New to forum, as well as new to the Android, Android Auto head units
I am looking for a better understanding of what's needed exactly to display the 'Torque Pro' app directly to a 'Head' unit without passing through a third device
I have the scanner port device
I have the 'Torque Pro' app running on the s9+ mobile device
Goal is to have the app running on a head unit minus the s9+
I have been reading, researching
Down to a Sony Android Auto unit
Or
Joying head unit that uses a sim card?
I am also concerned about quality of music playback, radio and FLAC files
Many thanks for your thoughts

To have OBD directly your only option is an Android based unit like the Joying. Android Auto just mirrors certain apps from your phone.

You'll need an OBD2 dongle. Just install Torque on the head unit and link it with the dongle same as you would with an Android phone.

Would this obd2 dongle be a USB, Bluetooth or WiFi connection?
I'd still want to be able to connect to phone to the head unit for calls etc. But for the torque Pro to work without the phone.

Yes, Bluetooth connection from head unit to OBD II adapter. You can have multiple Bluetooth connections so your Anroid head unit will be connected to your phone for voice and media and the OBD II adapter for data.

Bluetooth not connecting to car

having trouble connecting the Bluetooth to car
Keep giving me " no compatible device was found " in the car side and "connection time out" the Android side
Car is Mercedes GL 2013
Android 10 head unit from China
Photos attached

Not Android Auto, requested move to Android head units forum.
You might find out what unit you have and search for topics from the MCU version of the head unit.

You can´t connect to the car BT-Device.
There is only the possibility to connect to a phone with activated BT on it.

Thank you,
a bit strange ! I wanted to transfer the audio to the car through Bluetooth instead of the AUX cable
Any software modification possible?

No, BT is not possible to modify.
You just can connect to OBD devices (some at least) and phones.

I could not even connect to OBD devices.. tried two OBD devices !
I managed to connect my phone only

You need to delete all connections on the radio and the connection to the unit on your phone.
After that has been done, reboot phone and deactivate BT on your phone.
Reboot the head unit and first of all, bond the OBD device. Take care that the pin code is set correctly on your unit. It´s almost 0000 or 1234.
When you finished bonding your OBD, connect your phone.
It works only in this order.

Identify android head unit with BT problem

Hello! I've got Winca W2-RL1051 Android 9 Head Unit. Unfortunately I can use bluetooth connection with my iPhone only. OBDII adapters (I've tried four models) don't create a pair with it. Head unit finds it, requirea password, writes "Connect OK", but it doesn't work in Torque or Hobdrive. I hope the problem is in soft.
I attach HWGEtInfo.zip from my head unit. Can anyone tell me what to do?
Thanks in advance!

Based on the HWGetInfo you do have a FYT compatible unit.
Does the name of your OBD device start with OBD or Gooddriver? If yes, it should be able to pair. If your OBD device has a different name you can forget it (although you might still try #14 of my Q&A thread)
Secondly: These units are quite stupid. What is the pincode you need to pair your OBD? If it is different from the standard pin code (1234 I think) of your unit, then change the pin code of the unit to the OBD pin code.
First unpair your iphone (same for android phones btw) and completely forget it.
Then (try to) pair your OBD device.
Then pair your phone again.

Thank you. The name of my device is 'OBDII". I tried, but it doesn't work. Maybe it's because of I don't know how to completely forget my iphone after unpairing. There ain't such option in Settings menu, Should I root my head unit?

No. rooting your unit doesn't make a difference at all.
Does your phone see it and can connect to it when you plug the OBD device in your car?

Yes, OBD device works ok with android phone and tablet. No problems at all.
Head unit can connect with phones only. It doesn't see another bluetooth devices (e.g. remote controller).

Settings -> Car settings -> Extra settings (password 123456) -> Config info ->
If the checkmark is in the BC6 checkbox, then you need to deactivate it and select BC8.
If BC8 is selected, then deactivate BC8 and change it to BC6, reboot the device,

There's no such options in the settings of my head unit, alas.

Literally have the same problem with you bro.
My headunit is 8227L china crap

Literally having same issue and also 2 of my friend's with our new head unit.
My headunit is a RK3399 PX6 from Sygav.
Obd2 shows in bluetooth menu but won't connect ever after using code 0000 and 1234.

Have the same issue. Gave up, return all OBDII bt devices. I saw a video by Charlston. He said Bluetooth obdII has to be in top level. So if you have multiple devices, remove and forget them and put the OBDII first (first position). If you get it working than put your smart phone in. Will try to add his link.

Anyone have problems with the Rear Defroster/rear defogger not working? It worked with my original unit. Guessing the wirings incorrect on the new Allwinner T3 I bought. XRC-403 2019 04 12. Guessing that's the number on the back of the unit. I have a Single Zone.

Can you help me connect Bluetooth obd2 adapter with Nakamichi android car stereo. The Bluetooth settings in the unit does not have the option to change the password which is 0000.All my obd adapters use 1234.Please help.
Also the joying unit in my other car connects with adapters that only have obd2 as their internal name..

If Bluetooth is capable, why my previous head unit could connect with every device?

So, if in this forum some people say it is not possible to connect any device via Bluetooth except for the phone because it is soldered to the HU or whatever, why my previous head unit with the same wires and android version could do it?
I ordered a boison px6 and test it but I had to return it for some size reasons. I got to make it work with an OBDII and Bluetooth multimedia remote control with NO ISSUES, directly from the Bluetooth settings.
So, now reading the posts in this forum, it seems my new Joyix head unit, which seems to be almost the same unit except for the size, it cannot connect to any device via Bluetooth... how is that possible?
By the way, the seller doesn't agree.

I'm not sure where you got that information, but it is not entirely true. The bluetooth is capable of connecting not only phones, and phone audio but elm327 based obd2 adapters as well. All the units I have had, have this capacity.

Can a Bluetooth Device (not smartphone, not OBD) works with Android PX5/PX6 device?
I have a Dasaita PX6, with Hal9k ROM and RF210 bluetooth module. I can only pair smartphones and OBD devices. I need to pair a bluetooth lights module to control ambient lights but BT can't recognize it (my phones can do it). I read something...

Well I have bought a separate Bluetooth wifi dongle and I will write here if I got to pair both the OBDII and the Bluetooth multimedia button on the wheel.
