Re: Enable only audio on HDMI

You could switch to the audio jack. Or to stop sending a HDMI signal you could run this in the terminal: vcgencmd display_power 0 Though your screen may stop playing the audio since it will think the hdmi was unplugged. Additionally, you could cover the Pi's output by viewing a black image in fulls...

Enable only audio on HDMI

Hi,

I have my Raspberry 3b+ streaming audio through HDMI, connected to a Control4 system. Is there a way to disable the video output on HDMI and leave only the audio?

Re: udisks and udisks-glue no more inj Buster

I do remember that I changed something in udevil for my own, I don't remember what exactly, but I am sure it was nothing important. To enable it you might need to enable the systemd service as the user you want the USB drives to be mounted, for example: sudo systemctl enable [email protected] Replace "pi" ...

Hi, thanks for answering. That device is really interesting, but I was looking for a way to use the internal Bluetooth, without adding more complexity.

Hi all,

is there any way to increase TX bluetooth power? I am using Raspi to stream music to a bluetooth speaker, but am experiencing a maximum range of 5-6 meters.

WiFi Connection manager with fallback web configuration portal

I have realized an unmanned embedded project with Raspberry which works on WiFi. Now, in order to let it really flexible and portable, I need an easy way to choose the WiFi AP to connect to, without the need to access to the SD or other "acrobatic" processes (ethernet/video/keyboard). With Arduino/E...

Re: Is it reliable to backup Raspi from remote?

In embedded systems one usually don't need full system backups. Correct, "usually", but that's not my case. The usual solution to the problem of having your storage in an indeterminate state is to keep temporary files in RAM and to synchronize them to storage on a schedule. This also helps keep fla...

Re: Is it reliable to backup Raspi from remote?

@rln: So, in other words, there's no way to backup a Raspberry embedded in a big project without stopping everything, unscrew, unplug connectors and remove the raspberry in order to get access to the SD card?
If it's true, Raspi should not be so popular.

Re: Is it reliable to backup Raspi from remote?

I have checked the cli version and it is using dd without unmounting devices.
I don’t want to install a GUI as it is not needed in the project and I don’t like GUIs for embedded scopes.

Re: Is it reliable to backup Raspi from remote?

Although PINN is primarily an os-installer/boot-manager, you can also hide PINN so you don't even know it is there in normal use. When you want to perform a remote backup, you could enable it, do the backup and then hide it again. It only takes up about 60MB of your SD card. I will investigate this...

@B.Goode
Thanks for your reply. I don’t know how SDCardCopier works as I do not have a GUI, but I have investigated other cli tools and all of then make a brutal dd copy of the whole SD, so I believe the GUI tool acts the same way.

You probably would either have to code, or use software, or manually VNC into the Pi and backup to a SMB share.
I have ssh accesso to the Raspi, that's not the point.
