Allwinner R16 : pair ELM 327 Bluetooth OBD adapter

Hi,
I use a ELM 327 Bluetooth OBD adapter with Torque Pro on my Android Phone and it works great.
On my Allwinner R16 unit (Android Auto), I can't pair my adapter.
The unit came with a bluetooth app that only "see" my phone (looks like only phones can be discovered), and no other option to scan and pair a bluetooth device.
Am I missing something?
Any help would be greatly appreciated.

I had the same problem. I had to get a new dongle that does not have a passcode. These headhunts' bluetooth implementation will not accept OBD2 dongles that required a passcode while pairing. I am guessing it is due to poor design.

Go into the Bluetooth settings on your headunit and change the pass code to match your device.

Thank you, I will try that solution.

I tried doing so, setting my headunit to 0000 to match the dongle passcode. No go. I ended buying the no passcode OBD2 dongle for $20. Chinapost, 20 days to get to Florida.

@Gregory In the settings I do not have Bluetooth section.
The only way to deal with Bluetooth is through the bluetooth app that comes with the ROM (and it's pretty disappointing).
In the aforementioned app, I tried to set the same bluetooth pin code as the dongle but It does not works.
My guess is that it only pairs with phones and nothing else.
Here is the only way I have to manage bluetooth...

New android head unit

Hi guys!
Finally it looks like I'm going to replace my car, and I'm going to take my a amplifier and components to a new car, but not the head unit. I'm seeking to buy a new android head unit, and found this one on eBay:
https://www.ebay.co.uk/itm/25369100...7d776fc1640a9cbe7502037fff88436&ul_noapp=true
The main issue is that unit should fit Volkswagen Jetta and should have pre out, so it will be connected to external amplifier.
What do you think about unit I mentioned above? Any other suggestions?
Thank you

I have one of the smartech ones from ali express which I am impressed with

Thanx for advice!
I see that all these units can be connected with standard connector (i think it calls ISO connector), and also there are RCA outputs. Are these RCA outputs come before the internal amplifier and can be connected to external amplifier?
Thank you

All units can use an external amplifier. all of them have RCA for this.
All the specialised units like volkswagen, mercedes come with Quad lock and not standard ISO tho.

so if i have VW, i must look for the HU compatible specifically with VW?

Hi guys!
I'm waking up my thread. Almost month ago i got this unit https://www.ebay.co.uk/itm/10-2-4G-...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649, it should be (according to description) be compatible with my VW Jetta 2015. But once it was installed and connected it behaves little bit strange: all car info (such as doors status for example) and steering wheel control works till the engine starts. When engine was started all these things stopped shown and work. I checked that power cable is not connected, and the seller sent me a new CANBUS, but it still doesn't work. I will appreciate any help on this issue
Thank you

Solved - just used the canbus decoder from previous installed system

Did you find any solution?

Hi! I have the same problem with TPMS device USB connectivity with Android multimedia head unit. I tried everything, but so far no result.
Did you find any solution?

Hi! I have exact the same product and i see exact the same pictures, that means I have the same issue on my head unit PX6 with Android 11. I also updated the app to the newer version without any result. Any idea someone?

Hi, I didn't solve the issue. I have tried TPMS on two other car Android multimedia with Android 6 and 7 versions, but without any success.

Do you guys own the TPMS from the head unit seller?
If not there is most probably the issue.
There are wo many aftermarket TPMS... and the head unit supplier just implements their own stuff. Also OEM TPMS are mostly not supported.

TPMS is not from the head unit seller. Supposedly it should work with Android car aftermarket multimedia, but it seems that's not the case.

Exactly!

If I have a look at the provided pictures... It seems to be clear: The TPMS on the wheels are not connected. They need to get activated wheel by wheel.
So go through the settings of this app and try to get them activated. Ask the reseller how to activate if that is not written anywhere. If this is not possible: Send them back and get your money back.

Sorry, byt this is not correct. I 've tried everything, but the problem is not the avtivation of the sensors. The usb receiver can not be recognized by the HU. The app runs, you can choose the wheel sensor to connect, but nothing happens. The power light on the receiver flashes as before, and nothing more. Thanks anyway!

Sorry to say, but who told you that the car functions would work?
If I read the text at Ali, there is no single word written about car functions.
That what they offer is working... your steering wheel... nothing else did they offer...

Ok i see, would these functions work with a different canbus decoder?

In most cases the firmware needs to be developed to show the information as an overlay or pop up message.
May be there is someone here who has a VW which shows the information on the screen and you both can compare the content of the firmware and may be you are able to use another firmware from Joying on your unit.
I´m out here, because I don´t have a VW.

By the way...
As this unit is a PX5, you may be wrong in this forum.... May be post a picture of the "About Tablet" where we can see the MCU version of your unit.

There are some threads already open in this forum, so try to search for MF1-px5
Nothing I can support with this kind of unit.

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...
forum.xda-developers.com
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.
