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 or Edge 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 |
| Safari (macOS / iOS) | ❌ No |
| Firefox | ❌ No |
Browser access uses the Web Serial API, available only in Chromium-based browsers.
Troubleshooting
| Symptom | Fix |
|---|---|
| No Flipper in the port picker | Use a USB-C data cable, make sure the Flipper is powered on, and pick the device that shows up as STMicroelectronics Virtual COM Port. |
| "RPC session" stalls or times out | Close anything else holding the serial port — qFlipper, the Flipper mobile app, or another browser tab on lab.flipper.net. Only one app can use the port at a time. |
| 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 (and Chrome on Android). It uses the Web Serial API, which Safari and Firefox do not support.
