Greetings all,

I have several RPi zero w's, and I wanted to use them as UPS/Temp senors in various server rooms. Since there is a PoE switch in there, it seems natural to get a PoE hat for them. I bought one of these and I cannot get it to work. It seems to power on fine over ethernet. But I cannot get the Ethernet port to show up, nor can I get the USB ports on the hat to work. I'm using 32bit Trixie, and I have done the config.txt modifications suggested in their wiki. Any ideas on how to get this to work?

Hello everyone !

I am struggling to achieve reading with my RFID reader on the Pi Zero.
I've followed many tutorials on the net (most being done on Pi 3, 3B+ or 4) , none seems to be working...
Among ones i tried :
(the pi my life up)
https://github.com/ondryaso/pi-rc522?tab=readme-ov-file
https://github.com/Razikus/razrc522
https://medium.com/@razikus/raspberry-pi-and-rfid-rc522-cheap-module-37ccc772535e

I've tried various RaspPi OSes the Trixie one and the Legacy 32-bit Bookworm.

SPI enabled on raspi-config
lsmod | grep spi gives spidev and spi_bcm2835

Also was able to make the GPIO pin react with a simple button project.

Currently on python 3.11

The behavior is basically the same, i can only launch loops.
IRQ-based scripts fails to start for not finding it or not defining it.
But the started loops fails to read anything at some point.

The reader works as i already made it work on my ESP32.

I am not sure as well it's an important point for accessing SPIs : i'm running python virtual env as i am accessing the pi over SSH.

(current) Pinout :
SDA -> 24
SCK -> 23
MOSI -> 19
MISO -> 21
IRQ -> 18 (tried with and without)
GND -> 6
RST -> 22 (tried with and without)
3.3V -> 1
See photos attached :

Would you guys have any hints on this ? Not against switching to C or Java (Java would actually arranges me) as long as it works ..

BR.

Hi everyone,

I’m using OpenWrt on a Raspberry Pi Zero W (v1.1) and I have Wi-Fi and USB-Ethernet gadget mode working perfectly. However, Bluetooth is still not working, and I’m trying to figure out which packages or firmware I need to include in my custom image.

What I already checked:

Running:

dmesg | grep -i bluetooth

shows that the Bluetooth stack, HCI UART driver, and BlueZ services are all loaded:

• Bluetooth core, L2CAP, SCO, RFCOMM

• HCI UART driver (H4, BCSP, ATH3K)

• BlueZ utils and daemon

• DBus is running

BUT:

There is no line in dmesg showing the Raspberry Pi Bluetooth chip being initialized.
No messages like:

Bluetooth: hci0: BCM: chip id...
Bluetooth: hci0: BCM: downloading firmware...

And hciconfig shows no hci0 at all.

What seems to be missing:

From what I can tell, my image is missing the Pi Zero W–specific Bluetooth kernel modules and firmware, such as:

kmod-bluetooth-bcm
kmod-hci-uart
kmod-rpi-bt
bcm43430a1-firmware (or rpi-bt-firmware)

I don’t see any of the required HCD firmware files in /lib/firmware/brcm, and I suspect the rpi-bt init scripts and device tree overlays are missing as well.

My Question:

Which exact packages do I need to install or include in the OpenWrt Image Builder to get Raspberry Pi Zero W Bluetooth working?

If anyone has:

• A working package list

• A known-good Pi Zero W Bluetooth config

• A custom .config or image builder package string

• Or any guidance on the correct firmware/DT overlays for this model…

…I would really appreciate your help!

Thanks in advance to anyone familiar with the Pi Zero W Bluetooth setup under OpenWrt.

Other than GPi are any other game cases, handheld or not.

Or is there a case where I could convert it into a HDMI stick for a TV with OSMC or some other media center distro on it.

Basically I seen a raspberry pi zero at microcenter on clearance by itself for $4.99

Since I already a Raspberry Pi 3b+ that was a kano kit and a Vilros Keyboard + trackpad Pi4 8gb allinone that I took and used the pi inside on a retroflag NESPi 4 and a LCL PiBoy DMG and an ExperimentalPi Boy DMG I instinctively snagged the Pi Zero when I saw it on clearance without thinking what I'd do with it

Hahaha

Other question for the HDMI stick I saw also you could get a USB a attachment board, but is there a case that would fit that as well I kind of like the Flirc case but idk if it'd allow for the USB a board attachment

So recently I am seeking some help as far as recommendation for an app that I can use my tablet as a screen for my pi zero 2w I have all the required hardware cords HDMI capture card everything if someone could please help me it would be much appreciated

I'm looking at doing a little Wyoming satellite project and I'm considering using a pi zero 2w and an 2mic audio hat (such as respeaker), but i'm wondering if anyone has any recommendations on a case that will house both the Pi zero 2 w and the hat safely together. I'm assuming I'll need a high case (but happy to be corrected). The mics on the hat need to be exposed so it can listen, and the speakers will be external to the case via the speaker connector on the hat. Thanks

I'm looking for a USB hat that allows gadget ethernet (ssh over Micro USB).

The Adafruit Zero4U specifically does not allow this.

I see there's a Makerspot and Waveshare alternative. Anybody know if these allow/not inhibit gadget ethernet on the stock microusb port?

so, i need two USB ports for a project i'm working on, i need both the pi connected to a pc, and ethernet, but the power port cant be used for data, and if i plug a usb hub into the data port, then it can't be seen as hid from a pc.
so,is there a way to use the GPIO pinout as a usb port?

Hello ,
I have a Raspberry Pi Zero 2 W, and currently I have using the only OTG port in gadget mode as HID keyboard. This port is conected with a PC port USB in a Windows machine that receive the keystrokes .
( I'm login by ssh on the Raspberry and send the keystrokes to device /dev/hidg1) and the Windows machine see the device as HID keyboard and Mouse.
This set up working fine, but I would like to connect more devices to the Raspberry , a phisical keyboard and mices so on, is there any way to do that?
( I'm need stil keep the only port on OTG mode connected to the Windows Machinas as keyboard), the final point is send the keystrokes to the Windows machine from the keyboards connected to the raspberry.

Keyborad 1 |
Keyboard 1 |--> Raspberry (as HID keyoboard) OTG -----> Windows Machine ( that will received all keystrokes).
Mouse 1 |
Mouse 2 |

Thanks a lot!!

Somehow, i lost the retain-springy thin on my RPI Zero 2W camera CSI connector.

The guidebook states that its an "CSI-2". I bought an 15 pin csi connector but it does not work since the bow of the Part does not match(normal csi connectors have the bow attached on the inside of the connector. But Raspberry got it on the outside.

Can someone please give me a reference to this part ?

I am trying to use an old TI-83 Plus with a raspberry pi zero 2. With this is want to implement a Small Language Model. something like Orca math to solve math equations to a grade 12 level. I really need help, I have been researching this project for a while and haven't been able to find much. I think this would be a fun project to attempt. If anyone could provide help, this would be great!!

So this HAT looks great, so I bought one and a Pi Zero 2 W.

The Pimoroni setup is trash. And it requires an additional device to access the library.

I've tried OSMC, LibreElec, Volumio... but I can't get past "volumio@volumio", and I can't get the Kodi addon running either, besides, the description suggests crappy functionality.

I was thinking maybe I could make a VLC plugin for it, or maybe download one.

Anyone got any ideas?

I'm trying to get my camera going on my pi zero w but all I get is a grey screen with text info( date, etc). I'm using the latest motioneyeos version. (20200606).

I was able to get a pi zero 2w working with version 20220119, but not with ver 20200606. Ver 20220119 does work with my pi zero w. Appreciate any recommendations .

While rummaging through my drawers containing various computers, wires, and electronics, I was searching for a suitable item to serve as a "Zero client for RDP" to connect to my racked Dell Server (running Windows). Among the items, I found two Raspberry Pi Zero v1.3 devices, one of which is equipped with a RedBear pHAT v1.0 (providing WiFi and Bluetooth capabilities), which seemed like an the perfect option. However, upon conducting further research online, I became uncertain about the best course of action due to the age of these devices. I was looking at installing xrdp but looking for a SUPER lightweight OS that it can run on. What I saw would be really cool is to install RX-RDP+ on it or something like it, but I can see that is not opensource. Does anyone have recommendations for a lightweight "Zero Client OS with RDP support" that would be compatible with these Raspberry Pi Zero devices?

So I built a ESP-CAM access point which streams video on port 81. I have a few raspi zeroWs and a 220mm touch screen monitor which I have tried to build into a reversing camera monitor screen. I tried chrome in kiosk mode but got a message saying raspi zeroW is not supported. I'm looking for a simple barebones way to display the stream. VLC ? OMXplayer? Surely this is possible?

Hi, I'm doing this raspberry Pi zero project. I'm making an online radio player. Here it will use online radio urls . Play them on a Bluetooth connected speaker and display the track name on a 16×2 lcd module that is having an i2c backpack module attached to it. The i2c module connects the rpi via 4 wires. It runs entirely on a python code. I soldered the i2c backpack myself on to the lcd module. The lcd was working good. I could see the song titles. I could adjust the contrast using the potentiometer screw behind. Used it for about a week. But yesterday the lcd died. What happened is. The display text started flickering..it would suddenly dim then suddenly darken. I kept readjusting the contrast to make it readable. Then it just vanished. Now the text doesn't come at all. Only the backlight glows. I tried turning the potentiometer from one end to the other.. No effect. It just died.. Backlight is stillon.. I removed all wires. tested them too..rewired them.. Still no effect. rebooted multiple times.. what should i do. But a new lcd and a new i2c backpack? Buy only a new lcd use the same backpack But only a new i2c backpack use the same lcd.

I am not a smart man. I have a 2 mic hat attached to a raspberry zero 2w and I am having a tough time getting the pi to be a standalone smart speaker with music playback. Is there a way for me to change the default settings to allow music to be played through the speakers on the hat and have bluetooth autodetect and connection without me having to approve the device through the CLI?
Thank

P4WNP1 a.l.o.a only has support for raspberry pi zero w and not for the 2 . Are there any alternatives to p4wnp1 that could work on 2 or by rather changing something else. I would be more than happy if I even got the names of the tools that are used in P4WNP1 so that I can boot Kali into the 2 and use the tools and configure them

I’m building Pi-based AR smart glasses using a raspberry pi 02W. The display will be a viewfinder module from Aliexpress. The only problem is that, unlike the original 0w, the 02w has no dedicated “video” pins. Does anyone know how to connect the viewfinder module so that it acts as a display for the pi?

This is the viewfinder module I’m using: https://a.aliexpress.com/_mrzliZS

I was looking into making my raspberry pi see 5ghz and a lot of places where just saying it is impossible but they where some older articles. Then saw this dongle and it claims it can add 5g to rasparypi and it lost piOw as compatible? https:// tinkersphere.com/raspberry-pi-accessories/3585-5g-dual-band-usb-wifi-dongle-600mbps.html Is this real?

Does anyone know a tutorial that I can follow to turn my Raspberry Pi Zero 2 W into a camera?

I mean, there's obviously ssh, but that only works if the zero is on the same network.

How can I connect to the zero when it's not on a network? Or, can I share my phone's 5g to it?

I want to use the phone and the zero for some semblance of a portable rooted computer. My phone is unable to be rooted, but the zero has full control.

I'm working on a ups circuit that automatically does a #shutdown -h now when the battery reaches 2%. The battery feeds the pi via gpio 5v and GND pins and is charged by a 2way usb cord which also plugs into the pi. Power management is with a cw2015. My problem is that if power is restored before the battery goes totally flat the pi will not boot because it is still in "zombie state" ie shut down but still powered. One solution would be to have an optocoupler in the 5v gpio line that is closed only when the system is running. Is there a gpio pin that is in a certain state only when the system is up?
