HUDiy launches fine but Android Auto does not... help

I had to get the new monitor and it's working fine to launch and I can even play music through the HUDiy part of the app, but I can't get Android Auto to start up. (I want it to start full-screen but it doesn't start at all.)
I have attached the monitor info that I have and the main_configuration.json.
Ideas?

Your screen has a resolution of 1920x1200. Running Android Auto in full screen requires setting the experimental 2K resolution, enabling DRM (available only on Pi 4, Pi5 and x86_64 platforms), and setting the width/height margins. In the attached configuration file, the rendering surface dimensions are set instead of the margins and the Android Auto resolution. The settings for a 1920x1200 resolution should look as follows:
Code: Select all
"androidAuto" : {
"speechAudio" : true,
"mediaAudio" : true,
"resolution" : "2k",
"bluetoothAddress" : "",
"autostart" : true,
"fps" : "60",
"dpi" : 160,
"widthMargin" : 640,
"heightMargin" : 240,
"width" : 0,
"height" : 0,
"x" : 0,
"y" : 0,
"gpsDataSource" : "GPSD",
"useRpiDrm" : true,
"dayNightMode" : "COMMON"
},
AndroidAuto: 2K: 2560x1440
Screen: 1920x1200
widthMargin = 2560 - 1920 = 640
heightMargin = 1440 - 1200 = 240

I just tried the changes and AA still wouldn't launch. HUDiy launched fine as you can see from the images that I attached.
(Music plays fine, and I even made a phone call and that worked amazingly well... through HUDiy, not AA.)
Ideas?

Does Android Auto work via USB?
In the photo, the hotspot icon is not visible in the status bar, which indicates that the hotspot is inactive. If the hotspot is turned off, wireless Android Auto will not work. What platform are you using Hudiy on, and what exactly is your setup? Did you modify any operating system settings or config? Please also send us the logs from the $HOME/.hudiy/logs directory.
Please also check that your Raspberry Pi has proper wlan country set

If you are using external WiFi adapter, please check that it supports 5GHz hotspot setup (according to your config file).

I'll be honest that I actually have 2 WiFis on my Pi5... wlan0 and wlan1... and I changed wlan1 to be the default *assuming* that HUDiy would always use wlan0 automatically.
Well, I see now that I am incorrect on that based on what that link showed, and I have now put the MAC address of wlan0 under the "hotspot" node.
I may not be able to test it though until after 6am EDT tomorrow (away right now), but I'll let you know what happens. Thanks!!

Yeah, I made the change to the hotspot node and still AA wouldn't launch.
Like I stated, I do have wlan0 and wlan1 and wlan1 (and USB WiFi dongle) is the default node for WiFi communication.
I want HUDiy (and by extension Android Auto) to run on wlan0 and I know that the Country Codes are fine on the Pi because before I added the wlan1 I successfully tested HUDiy/AA on this same Pi5 and it worked fine.
My Python script (an A.I.) works on default wlan1.
I have attached the modified main_configuration.json and the log.zip.

In the provided logs, it is visible that the hotspot is not activated due to a missing device with the provided address. Is the address you provided correct? Is the wireless adapter already set up when Hudiy is launching? What is the output of the
nmcli command?

Please try setting the address in main_configuration.json to 2C:CF:67:C3:7C:8C, as searching for devices in the network manager might be case-sensitive.
Code: Select all
hardwareAddress" : "2C:CF:67:C3:7C:8C",

Several more things had to be tweaked in the NetworkManager stuff as well as what you asked me to change, but it's ALMOST there!
The AA did start... for a few seconds... it actually looked like it might work, but then after maybe 10 seconds it just died. I tried it again and it would launch HUDiy, then AA would start to come up and it would die again.
I even placed the phone very close to the Pi5 (would would have made connectivity between it and my phone super easy), and that didn't seem to make any difference.
When AA died and it just went back to the HUDiy main screen the hotspot icon was missing from the bottom right, so I'm guessing that it's still a hotspot issue.
I will attach the newest logs (anything dated today) to see if anything jumps out at you. I appreciate the help, BTW!
