Install SigRoam Wardriving on your Flipper Zero
Install SigRoam Wardriving v0.9.1 onto your Flipper Zero from this page, over the Flipper's own RPC protocol. No qFlipper and no SD-card removal. The Flipper has no Wi-Fi radio. This app is the control head: Dashboard, Upload, Rank, Board tools, Settings and About. Probe and Raw log are under Settings. Wi-Fi is opened from Upload. Scanning, GNSS and the WiGLE CSV stay on the attached board.
Firmware type and Version are separate. Both files are version v0.9.1. The type selects which Flipper firmware the file was built for. You need Chrome, Edge or Firefox 151+ on a desktop computer and a USB-C data cable.
SigRoam does not provide deauthentication or handshake capture. The board's wardrive still follows Marauder and transmits beacons while it hops channels. WiGLE upload uses Wi-Fi after scanning stops.
What this release supports
| Board on the GPIO header | What you get |
|---|---|
| Scout Lite running scout-lite-v1.2.0 | Board tools, start recovery, the upload status line, and saved Wi-Fi names. The WiGLE CSV stays on the Scout Lite card. v1.1.0 does not list saved names |
| Another Marauder build | Generic pages. Those boards have not all been bench-tested here |
GNSS and a microSD card are required for a located WiGLE CSV. Flash the board from the Scout Lite page. Do not flash this .fap onto the ESP32.
Which Flipper firmware is compatible?
| Firmware type | Version | File |
|---|---|---|
| Momentum / Official 1.4.3 | v0.9.1 | sigroam-0.9.1-momentum.fap (API 87.1), installed as /ext/apps/GPIO/sigroam.fap |
| Official 1.5.1 / Unleashed / RogueMaster | v0.9.1 | sigroam-0.9.1.fap (API 88.2), installed as /ext/apps/GPIO/sigroam.fap |
The default type is Momentum / Official 1.4.3. If an older sigroam-0.6.fap, sigroam-0.7.fap, sigroam-0.7-momentum.fap, or sigroam-0.8 copy is still in Apps → GPIO, delete it so the menu does not show two copies.
After install, set Settings → System → Log Device to Off. The system log otherwise occupies serial pins 13 and 14. Open Apps → GPIO → SigRoam Wardriving.
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 sigroam.fap to /ext/apps/GPIO/ on the SD card. Your Flipper Zero firmware is not 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. 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 file does not match this Flipper firmware. Switch Firmware type and install again. Do not bypass the mismatch warning. |
| Two SigRoam entries in the menu | Delete older sigroam-0.6.fap, sigroam-0.7.fap, or sigroam-0.7-momentum.fap files from the SD card's apps/GPIO folder. This page writes sigroam.fap. |
| Connect fails immediately | Unplug and replug the cable, then reload the page. On Linux you may need permission for the serial device (dialout group). |

Frequently asked questions
What does SigRoam Wardriving do?
It is the Flipper control head for a survey. The menu is Dashboard, Upload, Rank, Board tools, Settings and About. Probe and Raw log are under Settings. Wi-Fi is opened from Upload. The attached board scans, receives GNSS and stores the WiGLE CSV. The Flipper has no Wi-Fi radio. This is an early release, not a product-v1.0 claim.
Which board firmware does it support?
Scout Lite firmware scout-lite-v1.2.0 gives board tools, start recovery, the upload status line, and sigroam wifi so the Wi-Fi page can list saved names. The WiGLE CSV stays on the Scout Lite card. v1.1.0 does not answer sigroam wifi. Other Marauder builds keep the generic pages and are not all bench-tested.
Which Flipper firmware can load it?
Pick Firmware type before installing. Momentum and Official 1.4.3 use the API 87.1 file. Official 1.5.1, Unleashed, and RogueMaster use the API 88.2 file. Both are version v0.9.1 and both are written to /ext/apps/GPIO/sigroam.fap. If the loader says the app does not match, switch type. Delete older sigroam-0.6.fap, sigroam-0.7.fap, sigroam-0.7-momentum.fap, or sigroam-0.8 copies so the menu does not show two apps.
Does it change my Flipper firmware?
No. It writes /ext/apps/GPIO/sigroam.fap on the SD card over the Flipper RPC protocol. Open it from Apps → GPIO → SigRoam Wardriving. Set Settings → System → Log Device to Off so the system log does not occupy pins 13/14.
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.
