Bluetooth option is missing from device settings menu

Hi.
I bought a headunit via ebay.
At device settings under wireless & networks section only wifi option is exists, bluetooth is misssing.
It must be bluetooth capable, because it works with android phone. Only one bluetooth icon is on the device homescreen which operates only with phone calls, contacts.
We have a bluetooth ODB item, but we cant connect it to the cars headunit, because there is no separate bluetooth menu under the device settings menu, where can i search or find BT devices, and therfore i can not pairing this ODB device to the headunit.
How to solve that problem? Is there eny idea or advice?
Sorry for my english...
Model number: CAR_G20
Android version: 5.0
Kernel version: 3.4.67
Build Number: ALPS.LD_kk1MP10.V2.2
MCU: XY-M4-AndroidBT-4730EU-180408

I have the same problem. Did you found the solution?

Many head unit suppliers do this. They compile a crippled settings apk without bluetooth settings.
There is not much to be done about that.

I have this on my unit, I bought it from Seicane (haven't found out who the manufacturer is yet).
The bluetooth isn't available to android, as it is a host device (can be speaker and hands free kit, not normal profiles for android).
Unfortunately even plugging in a USB bluetooth dongle doesn't help as they have crippled the settings

android settings, in the upper right corner of the magnifying glass icon, press. manually enter bluetooth, you will find bluetooth settings. in the bluetooth program, from the pairing of the phone, change the name and pin to 1234. ready

Android bluetooth

No, you won't. You are talking about the Settings apps on phones. Most head units Settings program don't even look like the phone settings app as they have Settings apps which combine Android settings with car settings. . Most head units Settings apps don't even have a magnifying glass icon to tap on.
What's more: The Settings apps in Joyings are compiled without bluetooth settings, and this is the case on many head units. You can easily see this if you decompile the apps as they are pure java. Most users do not even realize, but most head unit Settings app lack a lot more functionality than the (mostly) standard AOSP Settings apps on phones.
Joying apps have a special bluetooth app that contains part of the bluetooth settings to do the pairing whith a number of selected devices.
Most head units have crippled drivers with compiled in white lists and black lists that only allow paring the phones and bluetooth devices they sell.
Please let us know which head unit you have and please share a photo of your head units settings screen, with all those users who don't have that. Instead of advising people incorrectly.
For example you could look at this video to see how many head unit settings apps look like. You see the bluetooth app allowing "some" paring. Then you will see the difference.

Still no luck huh?

I just got a head unit that also has no Bluetooth settings and no apparent way to pair with devices. The difference is that mine came with an app called just "OBD" (blue icon) and it is there only to help you pair the OBDII dongle. You just open the app, scan, pair and open Torque.
I didn't find the app in the store, but I'm sure if you reach out to your seller, they will be able to help.

Any update sir. i also have this problem. i want to connect hondata using bluetooth. but my bluetooth only have function phone call, contact.
Bluetooth not same with android phone.
kindly please update if you found solution.

Ummm no he is 100% correct. Worked for me like a charm. Mabey you should pay somebody to do it

Junsun V1 - start equalizer/AUX/BT music/CarInfo... from launcher

Hi!
For some reason I cannot reply to the thread https://forum.xda-developers.com/t/junsun-v1-start-equalizer-aux-bt-music-from-launcher.4237797/ ( it keeps asking me to log in/ register and then sends me back to the homepage).
I just recently bought and installed a Junsun V1 Pro (got the base model - 1GB + 16GB).
I downloaded the bluetooth settings apk and installed it with the apkinstaller that was already available on the head unit.
For some reason the bluetooth settings apk keeps crashing when I try to open it?
I've never fiddled with things like these before so most likely I'm doing something wrong.
My only goal here is to be able to share internet connection to the head unit via bluetooth, since BT is always active on my Galaxy S10e and I can't be bothered to activate wifi hotspot everytime I get in my car.
Any ideas?
Thanks a million!

Install the app QuickShortcutMaker and try to find the activity to find and start Bluetooth devices list.
I thinks it's not 'BluetoothSettingsActivity' - but I don't know why...

Hello friend, I think that for your phone to share the Internet every time you get in your car you would have to use macrodroid.
I have it on my phone and I have it configured like this:
As soon as the phone detects the Bluetooth connection with my radio, it automatically activates the shared connection.
And when turning off the radio and disconnecting the phone from Bluetooth. It is programmed to automatically disable Internet Sharing.
I hope it helps. All the best!

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..

Unknown devices MCU and bluetooth problem

Hello everyone, first a greeting
and then I wanted to ask for information, having just bought an android car radio for my dacia sandero, and I found some problems:
1) bluetooth connects me ONLY to apple android phones but to no ODBII devices, I have tried 2 without success.
From here they go into settings I can't understand which car radio model is mine, Android 10 MCU STx, 8-inch display I try to attach some photos, if someone can help me with bluetooth or even flash the rom.
Asking sellers until now is unable to help me.
Thank you in advance.

Looks like you're looking for support for a new purchase or recent purchase. In the first instance, what does the seller suggest when requesting support?
If the seller is unable to help you with your purchase, take some time to read through the forums, you might find a number of answers to your questions, with a little effort. Be prepared to give back, contributing - writing about your finds to help others.
I noticed your original post in Android auto has changed from this duplicate post, but that doesn't change your involvement to do some ground work and using the search function.
XDA isn't paid support, if your seller isn't providing you what you need, you have to make some effort - like searching.

It´s always the same issue...
Pull out the OBD dongle
Switch off BT on any smartphones you are connected with the head unit
Delete the BT connection to the head unit on all phones.
Delete all BT connections from your head unit.
Do a cold boot
Connect the OBD dongle to the car
Connect AT FIRST the OBD dongle and test the connection.
After the connection is established reboot the unit
Wait until OBD is connected
Connect NOW your smartphone by activating BT on your phone and search from the head unit.

no success

HI.
I tried the suggestion without success, deleted the cell phones also restored the network settings at the time of the BT search (made from cellular settings) the ODBII device is found, but at the time of the connection it disappears and returns to the main search screen.

Did you set the PIN correctly? Mostly for these OBD devices is 1234 or 0000.

yes in car radio bt (phone) setting is presetted 1234, maybe better change in 0000?

That depends on the BT dongle.

I try to connect again with the mobile phone to verify the PIN of the ODBII, after I try again with the car radio,
or if better i can download/use another application to setup the BT
I would like to try other ROM if possible, since there are other problems
1) the cell phone usb dongle is recognized, but it connects ONLY in 2G / 3G despite being a 4G with reduced speeds of course.
2) the BT menu is very brainy compared to that of a mobile phone, I don't understand the reason to put it under the TELEPHONE menu instead of elsewhere.
PS. if u can do we can connect with messanger cam or whatsapp to see the situation in realtime.

All Android radios have a reduced BT setup.
You won´t find any other implementations.... and no, you can´t change the BT app, this is dependent of the hardware.
Check the Alwinner threads with MCU: STM*** for any updates regarding your unit. I don´t know if there are custom ROM available.
...and no, no support via PN/Messanger... sorry.

No problem for support its only not important chance, for MCU i don't know where i can find upgrade.
but a bit question, ROM Custom or Not i know what mean, but MCU what do? that dont understand it.
Custom rom? yes if possible but for me if work fine i do downgrade, somethime the ROM downgrade its better than
upper version.

MCU: This is the controller for your main unit where the SOC is mounted on. You need to stay on STM*** what is mentioned in the system settings. May be there is a newer one, but to be honest... Please ask in the related threads. We don´t need tons of threads about one and the same units.

Joying UIS7862 7" setup (Including working Android Auto Wireless)

Playing around with my new unit to try and get it configured. I thought I would share what I have done so far and issues I am having.
Root:
I tried creating my own flashable image, but it did not like my 6315_1.zip file, even when signed with SignAPKv2. I was able to decipher my way into 4PDA where a user had submitted a working boot image patched with Magisk (attached). I updated to Magisk 22 from the Magisk Manager after install.
Android Auto:
Three ways to do it.
CarLink (aka ZLink)
This has worked quite well for me, but only supports wired connections. Hopefully they will update soon.
HeadUnit Reloaded
Wireless Android Auto (Note: phone calls not at 100%)
You need to be on the beta version of HUR which supports wireless android auto.
For Joying to support it, you need to change the config.txt build prop to sys.fyt.bluetooth_type=0 (you can flash link below bluetooth0.zip).
Phone calls do not come through the stereo. In HUR I get the error "Bluetooth is not connected." The phone shows an issue with bluetooth connection and says to try rebooting.
I don't know if this is an issue with the unit and it's dodgy BT or if it is the beta version of HUR.
I'm trying others to see what happens with different settings
0 = Wireless AA, unreliable phone over BT
1 = Factory default, no wireless AA
2 = Bluetooth cannot connect to anything
3 = Bluetooth cannot connect to anything
4 = Bluetooth cannot connect to anything
***Potential workaround
Phone seems to work again if bluetooth is turned off then back on. This does not seem to affect AA since it is running through a direct wifi connection at this point.
I have set a tasker task to turn bluetooth off then back on when it sees the wifi direct connection made.
The phone still says "Bluetooth is not connected" during calls, but the
Base HUR settings to not take advantage of this really nice display. I set the following in HUR's graphics settings for a big improvement:
Resolution: 1240x720
DPI: 200
Render surface: SurfaceView.
Android Auto for phones
Looks pretty good. I'd love to be able to use it for other drivers
Problem
Cannot reliably connect to other apps. NPR One and Pandora both say "there is a a problem opening....."
These apps work fine if they are playing before you open.
Adding apps to skipkillapp.prop does not seem to help
Tasker:
Difficulty reading bluetooth connections. May be related to sys.fyt.bluetooth_type above.
Prevent force close when turning car off:
Added net.dinglisch.android.taskerm = -10 to skipkillapp.prop.
Seems to be working. More to come...
Other Issues:
Deletes all google contacts:
Well known issue, remove syncing google contacts under settings -> users -> accounts -> google.
To get contacts back:
Go to contacts.google.com
Select Settings (gear icon in upper right) -> Undo changes
Go back however far you need to when you still had contacts
Recently I reset to factory defaults which killed the ability to connect to google play
Fix found in Joying forums (here).
Download firmware and place on flash drive
Go into app setting and wipe storage for Google Play Services
Immediately plug in firmware USB and let it reinstall
Magically works again after reboot
FytHWOneKey
Doesn't seem to work on this unit. Developer previously mentioned mute button (seperate in other units) was a direct android call which could only be captured with Exposed?

Hi fellow, I follow ytour post and see that you know what you're doing with the headunit

I wonder what sys.fyt.bluetooth_type=0 does in hardware terms.
The UIS7862 unit has bluetooth onboard of the SOM as well as an external USB attached Bluetooth module.
So does sys.fyt.bluetooth_type=0 select the onboard Bluetooth and sys.fyt.bluetooth_type=1 select the external USB module?
If this is the case then it may be necessary to attach a bluetooth antenna to the Unisoc module. Although I believe one of the WiFi antennas does double duty as a bluetooth antenna for this purpose.

Correct.
Do not use sys.fyt.bluetooth_type=0 on uis7862 FYT. Doing so loses bluetooth Low energy (BLE) and your hands free audio likely sound bad.

Is there a page I can go to in order to see all the options to put in the config file in order to customize it. I love had my unit for a while but am just learning how to customize the firmware

Android radio and problem with central lock after install -Citroen ds5

Hello Everyone. Sorry for my bad english not my native language.
I read all internet and cant find solution to fix my problem.
I buy this Heade Unit - https://pl.aliexpress.com/item/4000...t_main.21.21ef1c24K3NInA&gatewayAdapt=glo2pol
Afrter install everything working fine (steering wheel buttons, 4g, GPS, etc) only one problem with cetral lock. When I turn off the ignition after about 5 minutes, the central locking does not work with the remote control, and when I turn it back on works normally. Funny thing is that 2 people bought this radio but with android 10 (i have 11) and they all work.
I check canbus setting in the herad unit option and i have RZC >Peugeot/Citroen>ALL. The name of canbus is Raise but i dont have on the list that name. I can change RZC to ALLWORLD>Peugeot/Citroen?DS5 but what I wouldn't choose the door functions,sensors etc - not working. Only RZC >Peugeot/Citroen>ALL. have correct setting, but what about cetral lock? how to fix that -it looks like the radio puts the key module to sleep. in the settings I have something like lock control but some pin wants:

You really should contact the seller.
As you did not show MCU and Android version, no one would be able to help here.
On top: The French cars are some sort of difficult and b i t c h y, when it comes to CAN connection and providing car functionality. May be you got the wrong CAN adapter.

Spoiler: photo about device
Seller send me canbus Raise like one the pictures
Spoiler: CanBus
tell me what to do?
And last thing he send me RAISE can bus and when i check in the settings i don't have that Can BOX TYPE, and must use like on pictures - because it's the only one that works (steering wheel buttons) but no central lock
Spoiler: CAN BUX TYPE
but i can update this:
Spoiler: UPDATE CAN BOX
can a bad canbox setting cause this problem?

Yes sure. Even if you chose the wrong type (low, mid, high)
Remarks:
That the door lock is not working anymore with connected radio, that tells me that there is a mismatching CAN box setting. Seems to deactivate the central locking mechanism, there is an interference in the CAN signals.
That should throw an error message in the OBD for sure. You need to get in contact with the seller again and tell him that there is an error which deactivates the central lock.
Ask the seller which CAN box settings to use. If the sell units for your car, they should know which version to use to get at least most things working as expected... But you should know: There is only a minimal set of functionality available for most cars. Mostly they are providing Clamp 30, Clamp 15, RVC and light.
If your car is not listed in the CAN settings, you should not count on any further functionality.
You can update the CAN box, if you have the right file for it. Did the seller send one to you?

I checked all settings. I can mark my car on the list but if i do this steering wheel buttons not working (only on that HIGH). I Update canbox but its nothing change (no new funcion, settings etc) work like basic.
maybe some settings of the radio cause the BSI to go to sleep. some function consumes energy and bsi sleeps to save energy.

Just to drop here some info that may be useful to someone. I had precisely the same issue with the central locking system on a Citroen C4 II e-HDI, basically same stuff as DS4. The problem was the canbus decoder (Raise). I was sent another one from simple soft (XP type) and it works perfectly. maybe it's helpful for someone else. regards

Sorry to resume an old post but I've finally managed to solve this issue without external players.
Basically, what happens is that the ****ty Canbus BOX "raise" it's like always connected and draining energy.
You can lost a lot of time talking to the chinese seller, OR (if you have a bit of DIY skills) you can simply connect the RED wire of the canbus box to any power source that goes on when ignition is on (for example any led or the lighter 12v).
After that you'll enjoy a car without any chinese headunit added issue!! Cost of this? 0 euros!

saw a few posts here about that other people can't connect the device also, they don't mention the BT options, and I can't access to the dev options only the factory settings requierd password, the password 126. (8888 gives me options to change boot logo)
the only option that's works for me(was the defult one) to connect my phone and see it in the bt app is this: GOC_BC5_3008
In the other options I can't see my phone and OBD2 when I try to detect new bt device.

Someone with the same issue
Bluetooth connection issues
Having trouble with OBD dongle. Have installed 3 apps and although dongle will pair with head unit, the only option to select within apps says 'dummy FF:00:00:00:FF:FF'. This comes up even if dongle isn't plugged in but at the same time dongle...

Which suggests its a issue with the unit.
You both look to have a PX5 (well maybe as you can never tell 100% with these units)

I tried this, saw the comments.
I can't change my BT password it's on auto option.
In other BT options in the factory settings I don't see on the bt app my phone or the OBD2, tried them all, some even crash the app.
tried to reset the bt and wifi settings but no change.

Post in the MCTD section, they are the maker. But the BT function is deliberately crippled in these units so finding a fix will be hard. I went FYT as the maker and can use OBD on BT and UsB.

sorry I don't know what FYT means.

The 2 major makers are FYT and MCTD, there are 100's of sellers but most are made by these 2 makers.
