Fake mobile network connection on a HuiFei KGL head unit?

I have some issues with TomTom Go from play store, it won’t start if I don’t have a mobile network connection, I took out the SIM card because I don’t want to pay 2 mobile carrier plans, so I am tethering automatically with tasker from my Note 4 when it is connected to the HU.
I asked couple questions regarding this to TomTom support but they can’t answer my question right now, it is escalated to their devolvement department.
I was looking for a xposed module or an app to make fake mobile connection.
Is there such thing, I found an old module but it does not work anymore and it is not supported anymore.
My HU is rooted and running on:
MCU: MTCB-KGL-V1.77
Android: 4.2.2_27082014
FW: 2.02
Any help is appreciated!

HELP! Dasaita PX6 Max6 Headunit wont connect with iPhone Hotspot

I’ve purchased a Dasaita PX6 headunit. It’s advertised as Max6. Here are the specs:
Build number:
rk3399-userdebug 9 PQ2A. 190305.002 20190828.185647 test-keys
Kernel version:
4.4.167
#593 Tue Aug 27....
MCU Versipn
MTCE_HA_V3.30_2
I am also running an iPhone XS on iOS 13.2.
I’ve tested the hotspot on my iPhone with other decided and they are able to connect. I’ve also tested other iPhones on the Dasaita to see if it will connect to them. Unfortunately, I’m not able to get any iPhone to connect to the head unit. The head unit is able to connect to other SSID that are not iPhones. Can anyone help me with this? Thanks!

Have you seen this?

Yes, I have. I've tried all the tips. Nothing. It's weird because the head unit can pick up other hotspots/wifi SSID, but it does not find my iPhone. Initially, I could see the iPhone hotspot. It says "Connected...Saved" - this repeats 3 times and then it goes away.

Is your hotspot configured for G and N?

Not sure - whatever the standard is for iPhone XS running iOS 13.1.2 - I assume it's AC...

There is no way I can configure this - it happens automatically in the background, configured by Apple.

Even with the new MCU 3.37 update, I still get this problem occassionally. I've been turning the personal hotpot on and off multiple times, before the wifi connects itself!

Dude! You’re luckier than I am! I have that MCU as well, but my hotspot is not found ever! After it’s found the first time, it connects, saves the SSID, and then never displays or connects ever again.
I think this is both an iPhone AND head unit issue. It’s weird because not only can I not see the iPhone hotspot on head unit while sitting in the car, but I can’t see it on other devices either. However, as soon as I walk about 5 feet away, I can see the ssid.
So weird.

Hmm, when you turn on personal hotspot for your iPhone, you got to make sure to keep the screen on, at the page where to turn on your hotspot to wait for the headunit to connect. Then keep trying multiple times, or change your hotspot password!

Could be the location of the WiFi antenna.

I had the same issue on my Samsung Note 10+, I had to turn off "Allow 5ghz" in my wireless sharing options advanced settings. Then my MAX6
connected.

I was having a similar issue with my iphone hotspot being found, but not connecting, just saying "saved." The was being caused by the bluetooth connection between the head unit (car kit) and the iphone. You need to go into the iphone's bluetooth connection settings for the head unit (car kit) by tapping the "i" icon and then turn off carplay in the settings there. This should allow the iphone hot spot to be found and connected to by the head unit. It worked for me.

Same for me... Sometimes, turning off and on the iPhone then connects. in some cases it connects immediately ... boh

MIUI 11.0.3 Bluetooth connection problem

Dear All,
I have bought this phone 1 week ago but I have problem with the bluetooth connectivity. When I would like to connect the phone to a bluetooth car device the pairing code request dialog not shows up and because of this the pairing fails. Do you have any solution for this? With Redmi Note 4 (MIUI 11.0.2.) the car works well. I tried it with other car devices but there was the same problem.
Thank you in advance!!!!:fingers-crossed:

Try going to Settings-Apps-Manage apps-Bluetooth and Clear data-Clear all data. It helped me for some time but now Bluetooth problems appear again and I have to do it every time after answering the call while listening to music via Bluetooth.

Hi! try changing your AVRCP version from 1.4 to 1.6 in developer options

Thanks for reply! Unfortunately it does not work! The pairing request dialog window is still not popping up...

Maybe you need te change the bluetooth notification priority to high and maybe check permisions.allow it to show on home screen etc

Thank you for everyone! I found the problem! The app of my bluetooth watch caused the problem, after uninstalling it the bluetooth works again.

I face a similar problem with skoda car infotainment.
In my case pairing is successful but on the first call connection breaks. Even if connection is broken and car's infotainment starts seeking for a Bluetooth connection Redmi note 8 thinks it is still connected and it stucks there. when connection breaks a message pops up that reads something about AVRCP not supported and redmi note not responding
A have unpair both devices many times but same thing happens again and again.
I have to point that i came from a Redmi note 6 pro, where EVERYTHING regarding bluetooth connections and multiple connections were operated just fluently. I have redmi note 8 just 2 days
On redmi note 8 are always connected an amazfit stratos and a meizu ep51 handsfree and there are some other apps installed like mifit.
Do you thing that i should start first by unistalling all apps?

i unistalled amazfit app and it seemed that was getting better but i assume that phone it cannot deal with multiple bluetooth connections. Unforunately it cannot managed android auto (wired connection) and car infotaimnet (bluetooth connection). On the first call connection drops.
I flashed a custom ROM- based on China roms- but things didnt got better. Having both redmi not 6 pro (which handles all bluetooth connections just fine- even transfering active call via bluetooth headset to the car infotainment as soon as it establishes a bluetooth connection while i am getting into the car) and Redmi note 8 on developer options i copy all setting from Redmi note 6 pro to Redm note 8 but all issues are still there.
I wonder if it can be used the bluetooth app from the Redmi note 6 pro to the redmi note 8 but i dont have the knowledge to do it

I have the same problem. It sucks that redmi note 3 which i had before worked 100% ok...

All these issues make phone quite useless considering that everyone goes wirelessly. I wonder if this disappointing case is claimable from Xiaomi.

just noticed the same problem, both of my RN8pro bluetooth mac is 00:00:46:00:00:01 which is nonsense.
maybe you all got the same mac as mine, which is generic mac.

How can I check Bluetooth mac address ? Do I think there is something can be done?

Settings > about phone > all specs > status.
There's a bluetooth mac near the bottom.

I checked my Redmi note 8. It's seems normal, 28:16:7f:b5:65:2b is it?

MIUI 11 - Android 10 version?

The only workaround i found is to keep one connected bluetooth device at a time. So before i get into my car i have to disconnect bluetooth headphones and reconnect them after. Bluetooth management of Redmi note 8 is a big mess. I assume that is a phone's hardware problem its incapability to manage two or more bluetooth connections simultaneously.
I contacted Xiaomi customer care regarding bluetooth issues and i was finally asked to perfrom a test. I wonder how a test could resolve it

In the attached screenshot in developers options the max connected audio devices option is 2 but it's deactivated so i cannot changed it eg to 3. Could it be the solution to bluetooth connectivity issues? Is there any way to activate this option and change it?

Bluetooth not working

Shouldn't have to "teather" it.
If you set up a wifi hotspot on your phone, your head unit should pick up the Wi-Fi and you will have internet access on the head unit.

BT type lost

Greetings. Whilst trying to get my OBD dongle to connect to display OBD data for FCCL I tried changing the module type in Fac Settings. I now, using genius, cannot remember the default. HU is a GS from Xtrons PQS1039BL. Many Thanks
