Fallback WiFi on boot, possible?

Hi there, I have two connections set up through nmcli. When I boot up the pi, I would like it it to attempt to connect to a specific one of those connections and if it fails to try the other connection. Is this possible? How would I do it? I am familiar writing in Python if that's needed, but I'm not super familiar with Linux. (I want to set this up via terminal, I am running the pi headless and configuring it over ethernet currently) The idea is if I boot the Pi and my phone hotspot is up then it will connect to that, otherwise it will attempt to connect to my home WiFi.

raspberry pi 4 can't be found on network

hello, i'm trying to do a headless setup on my raspberry pi 4 but i can't find my pi on my network. i'm using a 256gb microSD card and made sure to format it to FAT32. i flashed the raspberry pi os 64-bit and also tried the lite version. i set up the wireless LAN and allowed SSH before flashing. when i try ping raspberrypi.local in my terminal i get ping: cannot resolve raspberrypi.local: Unknown host. i made sure my computer is connected on the same network. when i scan the network, i don't see my raspberry pi either. does anyone have suggestions on how i can troubleshoot this?

Password Error

Hi! I am currently trying to set up my raspberry pi 5 128gb storage 8gb ram on my lenovo laptop, and I have ran into some errors. I tried searching online and nothing has helped me. Whenever I want to connect to the pi, the following occurs pi@[my-pi-ip]'s password: Permission denied, please try again. pi@[my-pi-ip]''s password: Permission denied, please try again. pi@[my-pi-ip]''s password: pi@[my-pi-ip]': Permission denied (publickey,password). I tried changing the password via Raspberry Pi Imager and rebooting the pi, but whenever I change the password, it automatically resets back to a random 25-letter long obfuscated text. I attached two images one containing my password (the shorter one) and the other containing the weird text that disappears when I try to select it. What do i do?

Best way to connect two remote Pi's

Hey, hope your doing well. So I will describe the situation I have and explain my problem. There is an Pi5 (has wifi and net power) that acts as an server somewhere deep in a building. And then outside there is a zero 2W that is connected to an camera( has no wifi and powered by batery) . How would I stream the video from the zero 2w to my server. There like 200 meters apart separated through doors and walls. I have thought of the following solutions. - Wfif bridge - High-Gain WiFi Antennas( If possible??) - Radio waves

[Solved] Raspberry Pi 4 "InStore Audio" Importing Help

Hi! Im in abit of a pickle with a project. I am working on a Raspberry Pi 4 running what seems to be a modified version of raspanOS to play music in-store. The company who made this is no longer in service and was bought out to be another company. I currently do not have the right permissions to import the songs into the folder the music player uses. I do not know the username or password of an admin who does, and the servers this device used to run on when connected to ethernet are long dead. I have sever tracks already downloaded, and on the desktop I just need help moving them, or running an alternative software that works just the same where music from a specific software is run as soon as the desktop is booted. I do have a seperate SD card I can sacrifice and the proper flashing tools. Im not the best at coding so I may need a simple guide or just someone helping with the steps.

how to fix kernel panic during installation of PiCorePlayer

Hi, i have a rpi 5 and i want to play some audiophile music on it and i was experimenting with the different media player OSes that the rpi imager offered. I had enabled SSH, username & pw and the raspberrypi.local host, but PiCorePlayer kept giving me the same exact problem shown in the image. I'm new to rpi and linux so im not sure what most of it means. Is it just user error or software error?

So I'm working on raspberry pi 4 for the first time and it's my first time working with Linux and python. For the project I'm working I need to download many different things and every tutorial uses the pip command. the problem When I go to use the pip command I get a bunch of shit about APT and I've tried so many different things to fix this such as installing pip through apt commands. I also get a bunch of errors saying install is not defined I'm just lost and I have many other questions but I want to solve one problem at a time and this seems to be my biggest issue at the moment anyone have any pointers?

[SOLVED] RPi 3 w/ RCA composite output no display after boot

The whole boot process is displayed correctly but the screen goes blank just after, no blinking line, keyboard input still works. The RCA display im connected to is a chinese radio with a display, i have the radio hotwired to only display reversing camera video input that the rpi is connected to. I have tried running both standard raspberry pi os and raspberry pi os lite which i am running currently. Only changes to the config file are:
ovrscan_left=30
overscan_right=30
overscan_top=30
overscan_bottom=30

[SOLVED] no space on drive when there is 100+GB free

i have a samba connection to my usb drive connected to my rpi5. its 115GB in size, but when i copy things over like 8GB, 5GB, it says there isn't enough space when i use filezilla to get it across it goes until around 4GB until it says the file already exists...... if i overwrite it will copy it again from the start, only until 4GB and stop. and if i just resume it doesn't copy it over either. i also tried to use mobaxterm to get it across, but same thing, once it finished there was only 4GB of the actual 8GB it most definitely has the space:
df -Th
Filesystem     Type      Size  Used Avail Use% Mounted on
/dev/sdc1      vfat      116G   22G   95G  19% /home/user/usb
on the other hand, i copied over a folder with multiple files in there, in total the folder being 16GB and it all copied over fine.. i'm not sure what's going on it could be because the files in the folder are all less than 4GB. but that still wouldn't make sense

[SOLVED] USB is not writable unless sudo after mounting

its a usb in my rpi5, type vFAT mentioned, i mounted it to /home/user/usb i got this in my /etc/samba/smb.conf: [private] path = /home/user/usb writable = yes read only = no browsable = yes now when i try to access this usb share from my windows pc, i can use username and password to see and view, but i cannot write or edit. furthermore if i login with GUI with <user> and access /home/user/usb from the RPI5 i still cannot write. PERMISSION DENIED. how could i make it so that everyone can read AND write, so i can move and edit files onto this share from my windows PC? i can write with SUDO though. thank you in advance fro your answers!

[SOLVED] Problems with KMS Resolution

Hey People, I reach out to you cause I currently try to set up my Raspberry Pi 5 Currently it's running with Dietpi installed and after boot you either can boot into LXQt Desktop Environment or Emulationstation. However after a recent update the resolution got changed to "3840 x 2160" Pixels and I can't seem to fix that. Previously I definetly used the "dtoverlay=vc4-kms-v3d" setting but when I try to activate that in dietpi-config it stays on 4k anyways. Also if I start the Desktop environment there the default res is set to 4k as well and while emulationstation itself runs on fullscreen on startup all the games will run in 4K Resolution as well (leading to them running just in the top left corner just like the terminal) on my FHD Display (kinda odd sigh) Now I hope you guys have any suggestions how to fix this Edit: By now I think it might have something to do with the EDID setting of the Elgato HD60 S+ I've plugged between my Pi and my Monitor which max. Resolution seems to be 4k. Seems like I need a solution to force EDID to be 1920x1080p only
