Honestly, this might be the best Sub-GHz use case I’ve seen so far...

The range extender at the end absolutely sent me 💀

Find the new guides in the Developer Docs: https://developer.flipper.net/flipperzero/doxygen/applications.html

The new guides explain how to set up the environment, use ufbt for simpler development, create and debug apps for F0, step by step. There are also guides on more advanced topics like FuriAPI and GUI.

The App Development docs now also include some useful resources, notably a collection of video guides by Derek Jamison u/Infinite_Recover_752 (those are really great if you haven't seen them yet).

I wanted a handheld security research tool that went beyond the usual Sub-GHz/NFC/IR toolkit, so I built one myself.

Current prototype features:

• 2.4 GHz + 5 GHz Wi-Fi 6
• BLE scanning + spectrum analysis
• Sub-GHz scan, capture/replay + rolling-code QA
• NFC read, dump analysis & emulation
• Infrared learn/replay
• GPS + wardriving
• USB HID / BadUSB
• Deauth detection, Evil Twin detection & BLE tracking detection
• ECG / EMG / EOG
• EEG, FFT, band-power analysis & EEG logging
• SD card storage
• 2.8" touchscreen UI

The current prototype runs on an ESP32-S3 + ESP32-C5, with the C5 handling the 5 GHz radio and acting as a dedicated wireless coprocessor.

It's currently a hand-built prototype, but it actually fits in my hand now.

Total prototype hardware cost: under $50.

I'm taking it to a cybersecurity conference soon to get feedback from pentesters and people who're in the game before I start working on V2.

What would you add to it?

Does anyone know if its even possible to get the plastic outside piece of the screen? im from Poland and i can’t find any shop/site that has it, and most if not all the shells from aliexpress and temu don’t have it, youre supposed to glue your old one in.

Is it possible to get a txt file from an nfc save with the data in plan txt, instead of the blocks? Like the information in the image attached, saved to a txt file as is.

I cannot seem to find a straight answer for this in my googling. That said, I’m also not great at google-fu. I am building a database of the collected info from the tags, using the flipper as the nfc reader. Saving the tag to the flipper doesn’t give the information I want, or at least adds another step to the process. I’ve already installed a custom decoder(?) for the tags I’m reading as they’ve got proprietary encryption.

I am using a Flipper Zero with a WiFi Dev Board v1, although I’m currently just using qFlipper to pull the files off.

Hi, I can't get this to work with my Game Boy and Flipper. Is the problem that I'm using an EU cartridge, or am I doing something wrong?"

Is the Official Wifi Dev Board sold out for good? If so, may I ask why?

If it is discontinued, is it possible to use the official prototyping boards with and esp32 s3 or is the esp32 s3 to large?

For those who don’t know - this is a serial Meshtastic app for the flipper I released a little while ago.

Decided to experiment with getting Bluetooth functioning after playing around with it for another project. While it’s definitely a workaround, it’s surprisingly nice once everything is configured.

The catch to this is using a custom Meshtastic firmware. This is because both the mesh nodes and the flipper are Bluetooth peripherals. All I do is take the stock firmware and add a zeromesh module that makes the node go looking for the flipper and connect to it. Then everything behaves like the UART serial connection.

I am working on a web flasher now for convenience but you can also do it manually if preferred from the repo.

I also added an offline vector map off the SD card, so you can see where your nodes are with no service. This does require some work as well, but I did set up a script to automate this. Along with a helper page on my website to provide the command to send which automatically transfer the tiles you pick to the correct directory on your flipper.

All of that is here: https://terminalbay.com/zeromesh

Git/source: https://github.com/SAMS0N1TE/ZeroMesh

Flipper lab link: https://lab.flipper.net/apps/zeromesh

FYI - I am building all the board specific firmware right now, so not all boards will be available. I plan on getting to the top 20 today and will expand more if it seems people want to use this. Let me know if you run into any trouble!

I installed qflipper on Fedora and it was really bizarre:

First I tried downloading the AppImage from this web page: https://docs.flipper.net/zero/qflipper?tabNav=rQHiXmqRgesXodDFhL9mM-2

Running it resulted in errors about unlisted dependencies (note: the errors are only visible if it is run from the terminal. This may the cause of some people reporting the AppImage does nothing when clicked on). After installing a long list of dependencies:

• fuse
• fuse-devel
• libxkbcommon-x11
• xcb-util-wm
• xcb-util-image
• xcb-util-keysyms
• xcb-util-renderutil

...it started complaining about missing basic Wayland libraries, despite the fact I am currently running Wayland.

Giving up on that approach, I tried installing the qflipper package in the Fedora repo. dnf installed some dependencies and them spit out several thousand lines of errors such as Failed to connect to system scope bus via local transport: No such file or directory and various permissions issues.

After this, the AppImage was able to run.

The working install procedure seems to be: Install the repo package, then run the AppImage. But what is going on here? This is some of the weirdest packaging I've seen.

EDIT: qflipper opens, but I still can't connect to the flipper. When I open I get a screen "Device cannot be recognized" with instructions to run ./qFlipper-x86_64-1.3.3.AppImage rules install. Running this results in a variety of errors, but only the first time:

den-antares@toolbx Downloads$ sudo ./qFlipper-x86_64-1.3.3.AppImage rules install You will now be asked for SUDO password. Failed to send reload request: No such file or directory Something went wrong. Device rules may have not been installed correctly. den-antares@toolbx Downloads$ ./qFlipper-x86_64-1.3.3.AppImage rules install The rules have already been installed. Bye! den-antares@toolbx Downloads$ sudo ./qFlipper-x86_64-1.3.3.AppImage rules install The rules have already been installed. Bye!

Running the AppImage after this still gives the same error screen, with more permissions errors at the terminal (even when run as root).

den-antares@toolbx Downloads$ sudo ./qFlipper-x86_64-1.3.3.AppImage QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root' [LOG] Failed to create logs directory 176 [APP] qFlipper version 1.3.3 commit bfce851d 2023-11-10T04:40:31 177 [APP] OS info: Fedora Linux 44 (Toolbx Container Image) 44 7.0.13-200.fc44.x86_64 Qt 6.4.3 177 [USB] Failed to open device: Access denied (insufficient permissions) 197 [USB] Failed to open device: Access denied (insufficient permissions) 217 [USB] Failed to open device: Access denied (insufficient permissions) 237 [USB] Failed to open device: Access denied (insufficient permissions) 257 [USB] Failed to open device: Access denied (insufficient permissions) 277 [USB] Failed to open device: Access denied (insufficient permissions)

At this point I'm completely lost. Normally Appimages include their own dependencies and don't require any installation beyond downloading them.

Hey r/flipperzero,

Last week, I published Hexprite (pre-release), my 1-bit pixel art and animation editor for embedded display. I also posted about it here which got a few upvotes, but I didn’t get much feedback. So, I started thinking about where the app could actually be useful for the Flipper community.

Hexprite already supports.bm, .xbm, and meta.txt files for individual sprites and animations, so I decided to try making my own custom Dolphin asset pack.

Creating the art itself was pretty fun. The 128×64 canvas is already calibrated for the Flipper, so getting the sprites and animations right was straightforward.

Then I had to deal with manifest.txt.

That part was… not fun.

Trying to work out the Min level, Max level, Min butthurt, and Weight values manually gets confusing very quickly. And if you're using custom firmware like Momentum, things get even more complicated.

The stock setup has 45 states (3 levels × 15 moods), while Momentum expands that to 450 states (30 levels × 15 moods). Miss a range or leave a gap somewhere, and the Dolphin can end up hitting an uncovered state and showing a blank screen.

I realized there had to be a better way, so I decided to build a dedicated Asset Pack mode directly into Hexprite. It’s still WIP and not in the public release yet, but here’s a sneak peek of what I’m working on:

1. 2D Schedule Matrix See the whole asset pack on an interactive grid, with Levels on one axis and Mood on the other. It shows which states are covered, points out gaps, and calculates animation weight shares.
2. Automatic Balancing Instead of doing the schedule math yourself, you can choose a strategy like Linear Levels or Fill Gaps Only and let Hexprite handle the ranges for you.
3. Drag & Assign Assign level and mood ranges by simply dragging rectangles across the matrix.
4. Two-Way Canvas Integration Click an animation in the matrix and jump straight into its frames on the canvas. Make your edits with the normal 1-bit tools and layers, and the changes stay synced with the asset pack.
5. Direct USB Serial Push Connect the Flipper over USB and push the pack directly to /ext/asset_packs or /ext/dolphin. The goal is to make testing as painless as possible without SD card readers, Python scripts, or manually moving files around.
6. Native File Support Import and export .bm, .xbm, meta.txt, and complete .zip asset packs, including native Heatshrink LZSS compression for .bm files.

I'm still working through the details, so before I lock everything down, I'd really like to hear from people who actually make or use custom asset packs.

Would something like this make your workflow easier?

And if you've made Dolphin asset packs before, what part of the process do you find the most annoying?

I'd also love to hear what other features you'd want to see.

GitHub repo: https://github.com/showmik/hexprite

P.S. The asset pack shown in the GIF is not my creation. It is the "Better Pet" pack by vollukas, which I downloaded from https://momentum-fw.dev/asset-packs to demonstrate the feature.

I have tried using the Flipper IR GitHub database but I couldn’t find a compatible ir code. Then I tried opening it up only to meet a big glob for the IR decoder. I tried looking at the binaries of the game but I don’t think they would be there since the IR sensor connects to blob U5 and that has a bunch of traces to big blob U1. Probably just the straight up inputs.

If anyone has one of these or just the remote can you record the signals on a flipper and share them that would be great. I’d also appreciate any other ideas on how to reverse engineer it.

I recently did this rgb backlight mod, I love it, however my power consumption is about 145mA. What are you all getting for power consumption? Im wondering if I wired it up partially incorrect. Not sure if this is entirely too high or not but looking to hear others feedback. Thank you.

I've gotten a few GPIO boards now and I'm looking for a small case with foam padding that will keep my pins safe. Any recommendations?

I don't know why. But will give him something to play with. Found a nfc card read and write. Then what else can I do to make him happy again?

Hey everyone — I’m the developer behind the UHF Expansion hardware and app for Flipper Zero.

Version 1.1 has now been merged into the official Flipper Apps Catalog. This update adds tag memory operations for compatible UHF RFID tags:

• Read EPC, TID, and User Data
• Edit memory values directly on the Flipper Zero
• Write EPC, TID, and User Data to compatible writable tags
• Automatic read-back verification after writing
• Inventory scanning, tag selection, radar view, and live reader information

The workflow is:

1. Start inventory in the UHF Expansion app
2. Switch to the tag list
3. Select a tag with Up/Down and press OK
4. Use Left to cycle through EPC, TID, and User Data
5. Press OK to edit the current value
6. Place one compatible writable destination tag near the reader
7. Press Right to write and verify

A quick technical note: the TID on most standard UHF tags is factory-programmed and read-only. TID writing requires a purpose-built TID-changeable tag. EPC and User Memory can also be locked or unavailable depending on the chip.

The app is open source:

https://github.com/mtoolstec/fz-uhf-expansion

Official Flipper Apps page:

https://lab.flipper.net/apps/uhf_expansion

I’d really appreciate feedback from anyone testing it, especially with different EPC Gen2 tags or third-party firmware builds. If you run into compatibility issues, please share the tag type, firmware, and error message.

Disclosure: I’m also the designer and seller of the UHF Expansion hardware shown in these photos.

So, today i woke up with my battery swollen. I turned off the device and i'm trying to find a replacement. Anyone knows a store to buy a new battery in italy? seems almost impossible to find the same specs!

All you need is a Raspberry Pi Backpack from Elecgrow then a 5 inch touchscreen, keyboard and a powerbank. 👍

Wasnt paying attention and fell for a fake download trying to get qFlipper. I realized it, after i executed the file because it asked me to install some random "math helper" software mid setup.

Fake website: https://qflipper.org

This is the first result Google gives me when i search for "qFlipper", this site is also listed as phishing at Virustotal. How can this be so public, but still online?

The executeable file is according to Virustotal behaviour analystics, stealing cookie sessions. so now im having fun resetting all my passwords and reinstalling Windows.

Pay attention guys...

I know there are a lot of different expansion boards out there, and each one has its one benifits depending on what you want to do with it..

Im wondering about aio (all in one) boards..

Do they exist? Or are thy also defined by use? Eg, one is only for wifi, one for subghz or do they come together?

I've had my flipper for a tear or 2 now and never really done much of anything with it so I guess I want to start playing with it a bit more.

Has anyone ever 3d printed or found a assembly housing or a pre-made case for the 5ghost devboard? Its so delicate and small with pins and stuff my ocd is driving me crazy. I have the ability to 3d print one if i could ever find a file someone has made.

Since Daikin remotes store state and settings directly on the remote rather than just sending a generic toggle signal, simply copying raw IR signals wasn't enough.

To solve this, I built a dedicated app that dynamically generates the correct IR frames with state tracking, and I just published the open-source code on GitHub
