Flipper Zero Control Skill#

Control a Flipper Zero hardware hacking tool via USB serial CLI or Bluetooth Low Energy (BLE) — no Android device or intermediary app required. Direct machine-to-Flipper communication with full access to SubGHz, IR, NFC, RFID, BadUSB, GPIO, file system, screen capture, and input control.

Inspired by V3SP3R but without the Android dependency. Four Python scripts, two transports, complete Flipper control from your desk.

Requirements#

• Flipper Zero with USB-C cable and/or Bluetooth enabled
• Firmware: Tested with Momentum (mntm-008). Should work with official and other community firmwares.
• Python 3.10+ with a virtual environment
• Python packages: pyserial, bleak, protobuf, grpcio-tools, Pillow
• macOS or Linux (BLE via bleak works on both; Windows may need adjustments)
• Optional: External CC1101 module (e.g., Rabbit Labs Flux Capacitor) for amplified SubGHz

Quick Setup#

bash

# Create a dedicated Python environment
python3 -m venv ~/flipper-env
~/flipper-env/bin/pip install pyserial bleak protobuf grpcio-tools Pillow

Recommendation: Use USB for SubGHz/IR operations and raw CLI access. Use BLE for wireless file management, GPIO, app control, screen streaming, and input automation.

Scripts#

flipper_cli.py — USB Serial CLI#

Direct plaintext CLI over USB. Best for SubGHz and IR operations.

Environment:

flipper_ble.py — BLE Protobuf RPC#

Environment:

• FLIPPER_BLE_ADDRESS — Skip scan, connect directly to address
• FLIPPER_BLE_NAME — Device name to search for (default: auto-detect)

Note: BLE requires USB cable to be unplugged — Flipper can't do both simultaneously.

flipper_screen.py — Screen Capture & Input#

Captures the Flipper's 128×64 monochrome display and provides D-pad navigation over BLE.

bash

~/flipper-env/bin/python3 scripts/flipper_screen.py <command> [args...]

Commands:

bash

flipper_screen.py screenshot [output.png]        # 4x scaled PNG (Flipper orange on black)
flipper_screen.py ascii                          # Unicode half-block ASCII art
flipper_screen.py press <key> [short|long]       # Button: up/down/left/right/ok/back
flipper_screen.py navigate ok down down ok       # Key sequence
flipper_screen.py watch 10 [output_dir]          # Stream frames for N seconds
flipper_screen.py app_control SubGHz wait:1 screenshot  # Launch app + actions

Actions for app_control and navigate:

• Button names: up, down, left, right, ok, back
• Long press: ok:long, back:long
• Wait: wait:1.0 (seconds)
• Screenshot: screenshot or ascii

flipper_subghz_ble.py — SubGHz over BLE#

Performs SubGHz operations wirelessly by launching the SubGHz app, navigating menus via button presses, and reading results from screen captures.

bash

~/flipper-env/bin/python3 scripts/flipper_subghz_ble.py <command> [args...]

Commands:

bash

flipper_subghz_ble.py read [duration_sec]        # Read mode (protocol decoder)
flipper_subghz_ble.py read_raw [duration_sec]    # Read RAW mode
flipper_subghz_ble.py frequency_analyzer [dur]   # Frequency Analyzer
flipper_subghz_ble.py saved                      # Browse saved signals
flipper_subghz_ble.py transmit <filename>        # Open saved file (⚠️ HIGH RISK)
flipper_subghz_ble.py status                     # Screenshot current screen

Note: Results are visual (PNG/ASCII screenshots) rather than parsed data. For structured SubGHz data, use USB transport.

Risk Classification#

Every command is risk-classified following a safety model:

RiskActionsBehaviorLowRead-only: info, list, read, scan, bt infoExecute freelyMediumWrite, mkdir, copy, IR, NFC/RFID emulate, GPIOExecute with noteHighDelete, SubGHz transmit, power off/rebootConfirm with user first

Rule: NEVER execute HIGH risk commands without explicit user confirmation.

Protobuf Definitions#

The scripts/proto/ directory contains compiled Python protobuf modules from the Flipper Zero protobuf repo. To regenerate:

bash

git clone --depth 1 https://github.com/flipperdevices/flipperzero-protobuf.git
cd flipperzero-protobuf
python3 -m grpc_tools.protoc --proto_path=. --python_out=<output_dir> \
    flipper.proto storage.proto system.proto gpio.proto \
    application.proto gui.proto property.proto desktop.proto

External CC1101 Module Support#

If you have an external CC1101 module (like the Rabbit Labs Flux Capacitor):

• Use device=1 in any SubGHz command for the external module
• Use gpio otg on (BLE) or power 5v 1 (USB) to power it via GPIO
• Always use an antenna — transmitting without one damages the module
• The external module typically offers better range and sensitivity

Troubleshooting#

• USB port not found: Check ls /dev/cu.usbmodem* — Flipper may need reconnect
• BLE device not found: Wake the Flipper (press any button), ensure BLE is ON in Settings
• BLE drops after use: Normal — Flipper sleeps after idle. Just reconnect.
• Timeout/no response: Flipper might be in an app — press Back to return to CLI
• Screen capture empty: Display only sends frames on change; static screens won't produce new frames
• SubGHz no packets: Normal if nothing is transmitting nearby. Try pressing a remote during a scan.
