Install RF Lab on your Flipper Zero
Install the PINGEQUA RF Lab app onto your Flipper Zero straight from this page — over the Flipper's own RPC protocol, no qFlipper and no SD-card removal. RF Lab is a 2.4 GHz spectrum analyzer + nRF24 signal generator built for the PINGEQUA 2-in-1 RF Devboard. You need Chrome, Edge or Firefox 151+ on a desktop computer and a USB-C data cable.
How does browser app-installation work?
Connect the Flipper over USB and click Connect. The page opens an RPC session, reads your firmware version, then writes the application file (.fap) to /ext/apps/ on the SD card — exactly what copying the file with qFlipper would do. When it finishes, open RF Lab from the Apps → GPIO menu on the device. No firmware is changed.
Which browsers can talk to a Flipper Zero?
| Browser | Supported |
|---|---|
| Chrome / Edge (desktop) | ✅ Yes |
| Chrome (Android) | ✅ Yes |
| Firefox 151+ (desktop) | ✅ Yes — first use adds a permission add-on |
| Safari (macOS / iOS) | ❌ No |
| Firefox (Android) | ❌ No |
Browser access uses the Web Serial API: Chrome and Edge on desktop, Chrome on Android, and — since Firefox 151 for desktop (May 2026) — Firefox. Safari and every browser on iOS are out; see Web Serial is not supported.
Troubleshooting
| Symptom | Fix |
|---|---|
| No Flipper in the port picker | Follow No serial port detected, then pick the STMicroelectronics Virtual COM Port. |
| "RPC session" stalls or times out | Close qFlipper, the Flipper mobile app, and lab.flipper.net; see Failed to open serial port. |
| App installs but won't open | The app is built for a specific firmware API version. If your firmware's API major differs, the loader refuses it — update your Flipper firmware (or install the build matching your firmware line). |
| Connect fails immediately | Unplug and replug the cable, then reload the page. On Linux you may need permission for the serial device (dialout group). |
About this installer
This page installs an application onto a Flipper Zero you own, using the device's documented Protobuf RPC protocol over Web Serial. The protocol implementation is original PINGEQUA code written from the public protocol definition; no firmware is modified. RF Lab is distributed under its own upstream license — see the rf-lab repository.
Frequently asked questions
What does RF Lab do?
RF Lab is a 2.4 GHz spectrum analyzer and nRF24 signal generator for the Flipper Zero. It visualizes 2.4 GHz channel activity and can transmit test signals using an nRF24 radio on the GPIO header — built for the PINGEQUA 2-in-1 RF Devboard.
Does it change my Flipper firmware?
No. It only writes an application file to /ext/apps on the SD card over the Flipper RPC protocol; your Flipper Zero firmware is not touched.
Which browsers can install it?
Chrome or Edge on desktop, Chrome on Android, or Firefox 151+ on desktop. It uses the Web Serial API; in Firefox the first connection also adds a permission add-on. Safari and every browser on iOS cannot flash.
