I have a generic PX5 head unit from Ali Express which I've had for a couple of years.
I've managed to sort out most issues but have not managed to find a solution to a Wi-Fi issue.
I use a 4g USB dongle for mobile data.
The Wi-Fi in the head unit has to be started manually every time I turn the car ignition on. this is despite having the unit set to automatically connect to available networks.
Is there a setting I have missed or is it normal to have to switch on the wi-fi manually every time I use the car.
In input gratefully received
Thanks

Hi All,
Recently purchased and installed a Joying head unit (4GB, PX5 Octa Core) (link to product)
As this head unit runs android I am trying to tether the mobile data on my android mobile over to the head unit via the bluetooth tethering function. Problem is I dont think its working. Does anyone have any experience with this or know how to get it working?
Steps:
On the mobile, make sure its connected to mobile data
On mobile, turn on bluetooth tethering
Pair mobile and head unit via bluetooth
Still no internet access
Can you access data via hot spot? Make you mobile device a wifi hotspot and connect the headunit to your hotspot.

Yeah I tried this and it works fine. I just though it be better to use bluetooth tethering seeing as the phone is already hooked up to the head unit via bluetooth. Using the WiFi hot spot option just adds another process to the mix.
Because Joying remove a lot of the standard android setting I was thinking there might be a way to access the default android settings again to be able to play around with bluetooth properly. While writing this thread up however I did email Joying about the ability to bluetooth tether and their response was:
"Our head unit can not support Bluetooth tethering"
Hi, I am trying to achieve the same solution however I do not think it's possible. My understanding is that the bluetooth connectivity allowed by the hardware in the head units doesn't cater for the 'full stack' of bluetooth functions, so we're stuck with telephony and audio only with no data transfer.
I would *really* love to be corrected though! It would be great if it could be solved by software alone.
Failing that, could a bluetooth USB dongle work to provide full BT support?

I consider this a bug. It did work on the Sofia 3GR units on Android 6.0.1.
It (currently) does not work on the Android 8 PX5 FYT units (like the OP has as well). Can't say anything about the QD units.
Well that gives me some hope at least.
I did note at least 3 'Bluetooth' apps running on my device (that I've been playing with since my previous post).
Perhaps a custom mod may be the answer...
Sorry proto, I've had about five units and all the same. You're right and it sucks. I don't think it's a big as I've come across it many times and only in a few eBay postings did the seller actually specify it has a general bluetooth connection. Otherwise toy even have to buy their obd to get that to work

Ok thanks for the replies. Hopefully it will be fixed with a firmware update in the future or something.
Is there are any news about this Bluetooth tethering?
I am really interested because my WiFi is really really slow...
I saw that some Bluetooth function are missing, like the possibility to remove paired device or select Bluetooth tethering.
It’s highly unlikely Joying will fix the Bluetooth, they would need to produce a seperate rom with normal BT configured and u would not have access to the Joying BT app.
Currently Joying route all Bluetooth communication via a service called btlink, from there it goes to the joying bluetooth app.
Joying have fundamentally changed the way the Bluetooth is configured so it functions with only their software.
All these headunit manufactures do this to the BT so it functions with their software and they never offer a fix

From which library/framework/binary/whatever is this btlink service started/called?

Remember that it only worked with a HACK. Joying intentionally disables this functionality.
Bluetooth information
Init.sy.rc
Service blink /vendor/bin/blink
Init.connectivity.rc
Chmod 0666 /dev/tty (This should be tty00)
Now I have modified mine but I think the system/vendor/ect/Bluetooth/bt_vendor.conf is set to
- UartPort = /dev/tty00
Blink is interacting with /dev/tty
Android system is interacting with /dev/tty00 ?
Hopefully all the information is correct as I have modified my unit lots to try give back the Bluetooth to the system and I didn’t keep many notes.
But in short the the system is trying to access the Bluetooth on the wrong Uart port, where as the blink is attaching to the tty device, allowing the joying software to work.
This prevent the android system & apps interacting with the Bluetooth.
Also this is the test app I have been using to try to get it to allow permissions to turn BT on, but it get denied every time
Bluetooth Discovery : Bluetooth LE Scanner
https://play.google.com/store/apps/details?id=com.manjul.bluetoothsdp
i have the 10.1 american version.
if i remember correctly, bluetooth has an issue when your using it as a "media" access point
i think the bluetooth is set for A2DP... probably physically somehow.

Did you try to create a symlink like
Code:
ln -s /dev/tty /dev/tty00
And is it indeed tty00 or tty0?
Did you give the scanner root access?
Bumping this for a slightly odder issue. I'm trying to connect my Joying stereo to a Hondata KPro ECU, it sees the ECU but refuses to link to it in settings, rendering apps like Hondata or RealDash useless, so in turn I'm using a crappy $20 tablet until someone can show how to fix this BT issue.
Joying was no help other than to tell me to buy their OBDII adapter, which I did, but LONG story this is a 2008 Honda engine in a 91 MR2 that has no OBDII port. I've bought an OBDII port off eBay and tried using pinouts from the ECU to hack together an OBDII port but no luck.
Having it via Bluetooth would be easier, it sees the KPro, so there must be a way.
same problem
dont buy this joying head unit

Hello Everyone,
I have Eunavi 2din Android 8.0 Octa Core 4GB RAM. Usually i connect it to my phone Via Wifi for Internet connection for Google Map, spotify, etc.
I am planning to equip 70Mai Dash cam to My car which have a wifi (Hotspot) connection.
Is it possible to connect Wifi to 70Mai to my Head Unit while still Connect to my phone? because i want to make it as wireless as it can, i dont want to use a USB cable/RCA to connect 70Mai to my Head Unit for display function.
Have you worked out 70mai connection to the head unit? how it works?
Hey everyone. I recently picked up an aftermarket Android Auto/Apple CarPlay unit for my 2014 Lexus IS. The unit I have is Android 10 with a Snapdragon MSM8953 Qualcomm Processor. I have a couple of issues that I need help with.
The unit connects to my phone through Bluetooth but as far as the hotspot goes, it doesn’t connect at all. Z-Link needs a hotspot connection and my unit doesn’t automatically turn it on for my phone to connect to.
Basically the same as #1 but my Bluetooth doesn't connect and when I do connect it, the hotspot automatically starts up and I have internet connection. So it's a hit or miss when it comes to Bluetooth connecting or hotspot connecting. One connects but the other doesn't. Vice versa.
I’ve noticed in many other peoples Z-Links, in its settings they have the option to “Connect Automatically”. I’m not given that option at all. Is there any sort of thing I can do to make Z-Link start automatically? Rather than having to press the application every time I start the car?
I am assuming that once I figure out how to open the z-link application automatically, both issues 1 and 2 will fix each other.
I appreciate the help! Thank you!

Hy. I had the same Problem with the same Unit in the same Car. I ordered a "only DATA sim for tablets" from my Provider and installed it on the internal sim-slot from the Unit, and my Problem was gone.
The Unit himself can not handle Thethering (also named as Hotspot) with a Cellphone AND the (Carplay-Anroid Auto) Connection to the Unit.
(BT is only to handshaking in the first step but then wlan is used to use Android Auto or Carplay function of this Unit)
Before you ask, yes- this is not a feature of the car, but the head unit. The car cuts the power to the ignition/acc wire when the key is turned off immediately, and the Atoto S8 gen 2 shuts off the display as expected. However, it does not "sleep" the app or shut down peripherals like USB ports and Wifi for a solid 5 min after.
I have a wireless charger as well as some accessories connected to some of the USB ports, and they continue to stay illuminated and drawing power even after I left the car. The Wifi too, and this is a more annoying issue as if I'm using, for example, a shared hotspot from the head unit's SIM card or have a wireless AA setup, it doesn't kill the connection when the car is turned off. My phone continues to try to stay connected to the car, which is especially annoying with wireless AA / Carplay, since your phone THINKS it is still connected, but you can't see/hear what is going on anymore. In fact, turning the key back on during any point of this 5 min delay will reveal the screen is still on and notifications have been sounding, etc, you just didn't know.
I kind of hate that. I want my phone to disconnect and go onto my home's wifi when I get out of the car and stop playing my music in a silent vehicle. I can either manually disconnect wifi on my phone every time I get out of the car, or wait 5 minutes for the car to finally shut that down and sleep.t
This is my first Android head unit that doesn't shut off and need a cold boot every startup so I'm very unfamiliar with how this works. Has anyone experienced this? Is there something I can do about it? Oddly enough, bluetooth DOES disconnect right away, so the head unit seems to know that it should turn that off right away with the car. I wish it knew to turn off wifi as well so that everything connected to it stops when the car does.
Hey. I do it the other way around. The head unit shares the hot spot from my phone. However, what I do should be useful for your situation.
I have a Samsung phone. It comes with Bixby, an automation app. I have it turn off my phone's hotspot when the Bluetooth connection is broken with my head unit.
You could do something similar to have it either turn off the wifi and/or connect to your home Wi-Fi when the Bluetooth disconnects. If you have a Samsung phone you could use Bixby and if not there are other automation apps like Macrodroid, Tasker and others that you can try.
I tried a SIM on my head unit but the head unit doesn't support the bands that my mobile provider uses...if you wanted to know.
Hi,
I just got my Android Head Unit installed in my car with Zlink to use Carplay. I am an experienced computer and iPhone user but have never worked with Android or an Android Head Unit. Can I and if so how do I connect a second iPhone to Zlink and Carplay?
only one device can be displayed

I know that because I have Carplay in my other car. But both I and my wife use this car and I can't find where/how to connect her phone too? When Carplay opens there are no such options so it must be in Zlink somehow?
that is in the iphone carplay settings and the radio automatically connects to the last paired device
I understand that but where do I add the second phone? Shall I turn mine off and let Zlink look for a new phone?
I have a problem that people can barely hear me on the phone. The Carplay volume was also very low but that I managed to fix with Siri talking and at the same time increase the volume on the steering wheel. Also it takes a very long time before Zlink / Carplay starts when starting the car. The guy I bought it from asked me to reset the unit.
First time I used it I connected wifi in Zlink but now on a video i saw the guy connected hot spot in Android. Which way should I use now after resetting the unit?
And thanks for your help!
you = I understand that, but where do I add the second phone? Do I turn mine off and let Zlink search for a new phone?
=yes, cancel your pairing and let the second phone connect
Ok got it. Can I make other settings in Zlink by opening the app?
not much
You forgot to tell me where I should connect my wifi? To Android system as hot spot or in Zlink option? My unit has a SIM card installed if that makes any difference?
The Bluetooth as I understand I will connect on OEM phone app?
carplay works with wifi and bluethoo transmission the sim is only to give internet to the android system (google maps etc) not for carplay actually carplay is on your mobile and mirrors your radio
the rest already in google

So I should connect both Bluetooth and wifi to Zlink / Carplay?
I don't remember any option to connect BT on Zlink?
I found out today that people can't hear me using Carplay phone because the Android unit uses a built-in microphone on the screen and not Mercedes OEM.
Is this normal?
