Dear Emil

I tried everything with automation and with manual connection baed on below steps:

tting rid of all automation and manually starting it all (regardless of Android version on master and slave):

Uninstall AAGW on the master

Start the headunit server from within Android Auto on the master

Create a hotspot on the master

Open AAGW on the slave and make sure it's not set to tether

in AAGW make sure you select the masters hotspot

If AAGW is set to non-root mode make sure you select the masters BT (just press the button AAGW will do a BT scan of nearby devices and you can pick it from the list)

Go to the car and plug the slave in

Start the car

If slave is running in ROOT mode, slave will first try to connect to the masters Wifi and you will see a notification on the master that AA is running, only then the car should recognise a plugged in device.

If the slave is running in non-root mode, first you will see a splash screen on the car, then you will see slave connects to masters Wifi (if not already connected), then you will see AA starting on the master.

In all cases slaves connects to car's head unit.

Slave connects by wifi to master

The problem starts when AA on master should start sending information to slave. AA does not start on master and no information from AA can be found on car's head unit. On car head unit I can only see Android Auto screen and black screen when for expample map from AA should be seen (when I connect phone by wire I can see map and not balck screen).

I started in AA on master head unit server, but it does not help.

I feel that there is only one step missing to get it all working, but without your help I am not able to make that last step.

Master - Samsung Galaxy S20 Ultra

Slave - Samsunb Galaxy S10

Car - Mercedes W213 (E class).

Please help, as I have not received any feedback from you on my 2 posts and 2 PMs sent in the past.
