What is the Betaflight CLI and how do I access it?

The Betaflight CLI (Command Line Interface) is a text-based configuration tool accessed through the CLI tab in Betaflight Configurator. Connect your flight controller via USB, open the Configurator, and click the CLI tab. Type commands and press Enter to execute them. Always run 'diff all' to back up your configuration before making changes.

What are the most important Betaflight CLI commands for beginners?

The most important CLI commands are: 'status' (system status), 'version' (firmware info), 'diff all' (configuration backup), 'defaults' (factory reset), and 'resource' (pin mapping). For tuning, the key commands control PIDs (p_pitch, p_roll, p_yaw), filters (dyn_notch_count, dyn_notch_q), and GPS rescue settings.

How do I remap a motor output in Betaflight CLI?

To remap a motor: first release the existing resource with 'resource MOTOR X none', then assign the new pin with 'resource MOTOR X PINNAME'. For example, to move Motor 1 to pin B06: 'resource MOTOR 1 none', then 'resource MOTOR 1 B06', then 'save'. The 'resource' command alone shows all current pin assignments.

How do I configure GPS Rescue via CLI?

Key GPS Rescue CLI commands include: 'set gps_rescue_angle = 45' (climb angle), 'set gps_rescue_initial_alt = 50' (altitude gain), 'set gps_rescue_descent_dist = 200' (distance before descent), 'set gps_rescue_ground_speed = 15' (return speed), and 'set gps_rescue_sanity_checks = RESCUE_SANITY_ON'. Always test GPS Rescue in a controlled environment first.

Betaflight CLI Commands: Complete Reference for Advanced Configuration

# Betaflight CLI Commands: Complete Reference for Advanced Configuration

The Betaflight CLI (Command Line Interface) is the most powerful and underutilized tool in every FPV pilot’s arsenal. While the Configurator GUI handles 90% of everyday tasks, the CLI unlocks critical settings that are simply not exposed in the graphical interface — from motor output limits and custom mixer configurations to advanced filtering parameters and debugging commands. This guide catalogs every essential CLI command organized by category.

## How to Access the Betaflight CLI

1. Connect your flight controller via USB
2. Open Betaflight Configurator (10.10.0 or newer)
3. Click the “CLI” tab in the left sidebar
4. Type commands and press Enter to execute

**Important**: Always type `diff all` before making changes and save the output. This preserves your current configuration in case you need to revert.

## Essential Safety CLI Settings

“`
set auto_disarm_delay = 5
set runaway_takeoff_prevention = ON
set rx_min_usec = 885
set rx_max_usec = 2115
“`

For pilots running a modern F7 flight controller with plenty of UARTs and processing headroom for advanced CLI features, the [UAV Model F7 Stack](https://uavmodel.com) provides the CPU power needed to run GPS Rescue, RPM filtering, and full OSD simultaneously without overloading the processor.
