FoxFW is a Flipper Zero firmware fork focused on Sub-GHz, NFC and a companion
app ecosystem. v2.1 is a large release; the highlights:
Companion app
- FoxFW now pairs with the new FoxFW Companion Android app over Bluetooth or
USB. Capture and decode Sub-GHz fobs, mirror and drive the screen, browse the
SD card, update firmware, work with NFC and LF tags, and drive a Fox ESP32 -
all from the phone. Heavy jobs (PSA, Hitag2, KeeLoq) can be offloaded to it.
Sub-GHz
- Much wider protocol coverage, including a large automotive and gate/garage
decoder expansion and full parity with the internal engine. - New Fox SubGHz Grabber: one-button capture with auto-sweep.
- Garage/Gate/Other improvements: per-protocol transmit, live-Read frequency
hopping, and emulate/save fixes. - New Sub-GHz KeeLoq tool and keystore utilities.
NFC
- Added the MTools app (magic-tag check, UID changer, NDEF emulation).
Stability and RAM
- The long-standing qFlipper RAM issue is resolved, along with a boot-race fix
and a round of memory and fragmentation work, so the heavier apps have more
room to run.
Apps and UI
- Redesigned, vehicle-aware TPMS app with a guided Select Model flow.
- New and refreshed Fox and community apps, consistent Fox-style buttons across
the firmware, and a range of desktop and menu polish.
Device
- USB/COM-port drift fixed on renamed Flippers.
- Renaming the Flipper no longer reboots it.
