Report how the Flipper can be reached (serial ports on macOS/Linux/Windows, plus the WinUSB fallback) and whether it is connected. Does not open a connection.

Open the connection to the Flipper (auto-selects a serial/COM port on any OS, or the raw WinUSB path on Windows when no port exists). Returns connection status.

Close the connection to the Flipper, releasing the USB/serial handle.

Get hardware/firmware details (model, name, region, firmware version, radio stack, BLE MAC, ...).

Get battery/charging telemetry: charge level %, voltage, current, temperature, health, capacity.

Get the Flipper's uptime since last boot.

Round-trip liveness check over protobuf RPC. Returns the echoed payload.

Run any Flipper CLI command and return its text output.

Examples: "help", "info device", "top", "free", "loader list", "storage list /ext", "gpio read PC0", "led g 255". Streaming commands (log, subghz rx, ir rx) will be cut off at the timeout — use flipper_cli_stream for those instead.

Run a streaming CLI command for a fixed duration, then stop it (Ctrl+C) and return what it printed.

Use for commands that stream until interrupted: "log", "subghz rx 433920000 0", "ir rx", "input dump".

List files and directories at a path (use /ext for SD card, /int for internal flash).

Get type and size of a file or directory on the Flipper.

Get total and free bytes for the /ext (SD) or /int (flash) filesystem.

Read a file from the Flipper. Text is returned decoded; set binary=true to get base64.

Write content to a file on the Flipper (overwrites). Returns the device-side md5. Set is_base64=true for binary content.

Upload a local file from this computer to a path on the Flipper's SD card; verifies md5.

Create a directory on the Flipper.

Delete a file or directory on the Flipper. Use recursive=true for non-empty directories.

Rename or move a file/directory on the Flipper.

Capture the Flipper's current screen (128x64) as a PNG image.

Send a virtual button press. key: UP, DOWN, LEFT, RIGHT, OK, BACK. type: SHORT, LONG, PRESS, RELEASE.

Reboot the Flipper. mode: OS (normal), DFU (bootloader), UPDATE. The connection will drop.

Play an audiovisual alert (sound + backlight + vibro) to locate the device.

Set an onboard LED channel. channel: r, g, b (RGB) or bl (display backlight). value: 0-255.

Turn the vibration motor on or off.

Control a GPIO pin. action: mode|set|read. pin: e.g. PC0, PC1, PC3, PB2, PB3, PA4, PA6, PA7. For mode/set, value 0/1.

Transmit an infrared signal. protocol e.g. NEC, NECext, Samsung32, RC5, RC6, SIRC. address and command are hex (e.g. 0x04, 0x08).

Send a signal from a built-in universal IR remote. remote: tv, ac, audio, projector. Use flipper_cli('ir universal list tv') to list signals (e.g. Power, Vol_up, Mute).

Transmit a saved Sub-GHz capture (.sub file on the SD card). WARNING: transmits on real RF — only use legal frequencies you are authorized to transmit on.

Listen for Sub-GHz signals on a frequency (Hz) for a few seconds and return decoded output. Common: 433920000, 315000000, 868350000.

List apps available to the loader (installed FAPs and built-in settings apps).

Launch an app by name (e.g. 'Sub-GHz', 'NFC', 'Storage') or by full .fap path. args is optional (e.g. a file to open).

Ask the currently running app to exit, returning to the desktop.

Scaffold a new Flipper app (FAP) with ufbt into the project's apps/ folder. appid must be lowercase letters/digits/underscore.

Build a FAP in apps/ with ufbt. Returns build success, log tail, and the produced .fap path.

Build a FAP and deploy it to the Flipper over USB (upload to /ext/apps// and launch it). No COM port required.
