I have tried it on 3 different pies, same result

Ideas?

Edit : first issue can be solved by adding dtoverlay=dwc2,dr_mode=host on config.txt instead, but mic issue still persists

i am a noob. I managed already to install emteria as android on my raspberry 4b. Then i installed the gx-android-display.apk software to have control over my victron cerbo gx stuff. I want the raspberry and the 7inch touch screen in my boat. I have the multiplus and a batterie. But i have managed to install everythimng on the raspberry so far, i also use the kiosk mode, that if i start the raspberry always new, the display GX software runs automatically. Well done so far.

But, as the raspberry always dont get power when i leave the boat, then 3 days later come back, i have to switch on main power also.That means the raspberry powers on and always comes this menu item "Modify system settings", "allow modifying system settings" where i have to select it. Then i have to acknowledge, before the soft starts. I want this to be removed, so the victron software starts with "power on" all the way through.....

Does this make sense what i said?? lol

Can someone help, to remove this menu ?

Thank you very much

Best wishes

Chris

I don't know how to fix this.
Any suggestion will be welcome.

The Raspberry 4 is always Online on the Emteria Panel while the Raspberry 5 stay online only for the first 20/50 minutes after it is turned on. After this time it goes Offline on Emteria Panel.

Both devices have the MDM flag active.

When I load MDM Settings App with the Raspberry pi 5 the device reconnects to the MDM and goes back online.

I also connected the Raspberry pi 5 to two different internet lines (ADSL and SIM) with the same result.

Do you have any ideas?

I’m developing a POS solution that relies on software from a PSP (Payment System Provider). The problem is that when the app runs for the first time, it prompts the user to grant permission for using a USB PIN pad. This user interaction is not intended.

Is there a way, through MDM, to pre-grant this app permission to access USB devices automatically?

I’ve already tried some approaches via ADB, but they haven’t worked as expected.

I try to arrange the config.txt and the cmdline.txt in the BOOT partition but it seems to me that it works only in the early phases of the loading process, after follows the display resolution. The issue arises if I connect a display that hasn't the 1080p60 resolution available: the RPi arranges the HDMI resolution to one of the available res for the monitor and, if I connect a 1080p60 capable monitor after, the requested resolution in the Emteria settings remains at the older one. I have an app that works properly ONLY at 1080p60 so I need that Emteria res remains to 1080p60 forever.
Thanks Andrea.

Does the automatic OS update feature currently work on Raspberry Pi 5 with this OS version?
Could there be any known limitations, or am I possibly missing an additional requirement?

Thanks in advance for your help!

I’ve enabled Kiosk Mode and set the app to auto-launch at boot, which works fine after reboot.
However, if the app crashes or is exited for any reason, it does not automatically relaunch.

Is there a recommended way to ensure persistent execution of the app in such cases (e.g., watchdog process, system setting, MDM configuration, etc.)?

Thanks a lot for your help!

I am evaluating Emteria OS on Raspberry Pi 4 (4GB). I tried to encrypt the device by going to Privacy and Security and clicking Encrypt Tablet.
But nothing happens. No error or message or anything. Seems like it's greyed out.

It's necessary to have encryption enabled for my usecase.

Please suggest what can be done to enable encryption.

emteria is 14.2.0 on a RPi4, connection attrempts were tried via Ethernet and Wifi (directly from Hotspot mobile phone)

Thanks for the help

That's the correct resolution. The Raspberry Pi Settings app on the device confirms the same - requested resolution 1920x1080@60, current resolution 1920x1080.

However when I open either Cromite or Firefox the browser looks like it has been zoomed in. The resolution they are using is 1440 x 810, according to a resolution test site. It means I can't fit enough detail on - the pages I need to use have been designed for 1920 x 1080. The browser zoom lets me zoom in further but not out. Does anyone know how to get a browser to run at the full resolution?

Thanks,
Stephen.

Any ideas?

Thanks in advance,

i am using HDMI port 0 with a 100Hz refresh monitor.

can anyone help fix this...

I also tried using adb via wifi and it worked, but I couldn't get the image via the scrcpy program (again - it works without a problem on lineageos).

Reading the internet, I came across guides that it is necessary to enable OTG. So I modified the config.txt file by adding the lines:
dtoverlay=dwc2

and in the cmdline.txt file after the fragment: roowait I added:
modules-load=dwc2,g_ether

but that didn't help. I connected with adb over wifi with the RPI, and executed with shell: dmesg | grep dwc. This is response:

Any ideas what could be wrong?

My device is:

• Raspberry Pi 4 with 8 GB RAM, 128 GB SD Card
• Emteria Android 14 (I also tried Emteria Android 13)

1. I could perform the first step in the instruction by opening the SD Card on my Windows 11 PC, which opened the boot folder, to extend the cmdline.txt at the boot partition. Other partitions are not readable on this Windows 11 PC.
2. But when I insert the SD Card back into the Raspberry Pi 4 and boot it up (step 3), I am unable to write to the /odm/lib64/hw folder via 'adb push' (step 4) because /odm is not writable.

• 'adb root' followed by 'adb remount' don't work with Emteria Android because adb complaints about not being able to run root on production builds.
• I can only connect to Raspberry Pi via adb WiFi, because it looks like connecting over adb USB is not supported on Raspberry Pi at all.

Therefore, either the instruction page does not mention what Android versions or builds such an approach works, or am I missing something in how to write to the read-only odm partition?

Thank you very much in advance for any advice.

Does anyone have knowledge of how to tweak the OS to allow me to go headless form the start?

Thanks

I only really want to install realdash but when I go to the APP store my PI5 isnt recognised as a device.

Any thoughts pls.

I'm trying to register a Redmi phone for MDM as per the instructions here: https://emteria.com/kb/device-enrollment-using-qr-code

After scanning the code and setting up the wifi, I get the error: "Can't set up device. Couldn't download the admin app."

Best,
Paulo

Any hints if that is possible at all?

I have tried my best to read all the support here first before posting, but I am a bit stumped. I have created a script named "gpio", and for the sake of sanity it currently contains only the example code from the site. I have placed it in /data/init.d/, set root:system as the chown, set chmod to 0755, and used dos2unix to ensure correct line endings. I have tried it with and without an extra line to write to the downloads folder to confirm loading. But no matter what I do the script will not run at startup.

I see a handful of the guides here are a bit older, is there any extra steps I am missing for Android 14? Are there any logs where I can see what is happening? Thanks!

When I recently downloaded and installed emteria.OS (v11.11.0) on a Raspberry Pi 4, a UUID directory is created under both /mnt/media_rw/ and /storage when I connect a USB memory.

Does this depend on the OS version?

Thanks

When I try the same webview app on a spare Elo Backpack 4 we have laying around it works perfectly. Is there a way to activate WebGL in the webview?

a list of language codes would be appreciated if applicable

I already tried using sudo commands and other methods to access as root like going through the folder in file manager apps, but none of them worked so far. Is there anyway I can get root access to modify the files and folders I mentioned inside Termux? Or is there something else I can do access the GPIO pin?

Am I doing something wrong, or is this feature not supported?

But how can standard apps (not ones I've built), gain root access?
I'm thinking of Tasker, file managers, Aurora etc. It seems like they think they don't have root access, I guess these apps are looking for "su" and can't find it?

There is some discussion of a root option under developer options (which I can't see).

Actually (as a BTW) I can't see the terminal under developer options either.

I was thinking I might have to symlink sushell to su but the correct way would be helpful.

I have activated a license for a RaspberryPi 4B, but while reinstalling the activation state shows as active but a text at the bottom says need to activate and is in trial version. Could you please help.

Are these known bugs and are there any known fixes?

Is it possible to run Emteria OS without a screen? I have a raspberry pi 4B on which I have installed Emteria 13. I believe it has booted but all ports are in an ignored state therefore I am stuck.

My use case is as follows.
I am blind and want to use the raspberry pi to run a program called the vOICe which conveys images through sound. See http://www.seeingwithsound.com for details.

I suspect accessibility tools are not installed on Emteria OS because it is primarily used in industrial contexts.

What can I do? Can I set any parameters in a configuration file where I can enable ADB or SSH on boot without having to do anything with the GUI?

Pranav

Thanks so much!

when creating a new thread, please follow a few guidelines:

• use the forum search to see if your question has already been answered
• if you are having issues please provide the hardware model, emteria version, connected periphery
• provide meaningful logs: https://emteria.com/kb/bug-reporting

This is on version v13.4.0.

I'm writing an app using flutter that need video playback which on version 11.11 does not work. Videos does not start on RPI4, when i tried it on other android devices problem never occurred so i think it must be something on the system level.

Anyone successfully configured ssh with keys on Emteria OS android 13?

Emteria version 13.3.0
Android version 13
Android timestamp 1675944107

On a Raspberry Pi 4

I have setup the necessary keys as described here https://emteria.com/kb/configure-ssh-server although I wasn't able to run adb as root on the new server connection and it responded with adbd cannot run as root in production builds when I ran adb root after connecting so I had to run various shell commands with sushell to get there.

I can connect from my Windows system using WinSCP and the appropriate private key, but when I try to use ssh, I get the message indicated in the title.

Do I need to modify one or more of the files in /data/ssh to get ssh connection

Cheers, Grant

Is there something like a deep sleep or standby on raspberry pi?

Reason: want to use it as a car PC but booting it every time I start my car will take to much time, but without one of these options it will pull my battery empty in no time.

Thanks in Advance for any feedback.

I'm interested in multi-display capabilities of Emteria.OS. My main interest is to run 2 apps at once on one RPI4 device, each one on separate displays.

On testing we noticed that an app in kiosk mode still displays the volume buttons from where you can enter the settings by using see more on volume control.

Is there a way to completely lock any access of the settings?

Have a great day and Happy Holidays!
