Release 2021.01 available for download

We’re happy to announce the availability of the 2021.01 release! The release includes the Crazyflie firmware (2021.01), the python library (0.1.13.1) and the python client (2021.1). The firmware package can be downloaded from the Crazyflie release repository (2021.01) or can be flashed directly using the client bootloader window.

Most of the improvements have been done in the Crazyflie firmware and include:

The App API in the Crazyflie firmware has been extended and improved to be able to handle a wider range of applications. The goal is to enable a majority of users to implement the functionality they need in an app instead of hacking into the firmware it self.

We have improved the Lighthouse support in the firmware and both V1 and V2 are now working well. Even-though everything is not finished yet, we have taken a good step towards official Lighthouse positioning.

A collision avoidance module has kindly been contributed by the Crazyswarm team.

A persistant storage module has been added to enable data to be persisted and available after the Crazyflie is power cycled. It will initially be used to store Lighthouse system information, but will be useful for many other tasks in the future.

Basic arming functionality has been added for platforms using brushless motors.

In the client the LPS tab now has a 3D visualization of the positioning system and a new tab has been added to show the python log output.

Unfortunately we have run into some problems for the Windows client build which is not available for this release.

Finally we have fixed bugs and worked to improve the general stability.

We hope you enjoy it!
