Versions:
cfcli 0.7.1 by Bitcraze is a lightweight command-line utility designed to configure, control, and automate Crazyflie nano-quadcopters directly from a Windows terminal. Positioned in the Robotics / Drone Software category, the tool exposes the full Crazyflie real-time parameter and logging frameworks, enabling developers to read telemetry, tune PID gains, update firmware, and script autonomous flight sequences without launching the heavier Python-based Crazyflie PC client. Typical use cases include swarm coordination experiments where multiple UAVs must be armed simultaneously, headless debugging of onboard sensors during hardware-in-the-loop tests, and rapid prototyping of new control algorithms against a physical vehicle. The executable ships in three published iterations—0.5.0, 0.6.0, and the current 0.7.1—each adding incremental support for newer Crazyradio PA USB drivers, improved Bitcraze Crazyflie API coverage, and more robust packet-error recovery. A concise sub-command syntax (scan, log, param, console, flash) keeps the learning curve shallow for researchers already comfortable with CLI workflows, while YAML-based batch files allow entire experimental routines to be version-controlled alongside academic papers or CI pipelines. Because the utility communicates over the same 2.4 GHz Crazyradio protocol used by the official graphical client, existing Crazyflie 2.X and Crazyflie 2.1 hardware requires no firmware modification to accept cfcli instructions, making the tool an unobtrusive addition to both classroom and laboratory environments. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
