First release candidate for 1.5.1. This release changes the estimator to EKF2 for all vehicles as it is the most tested in typical outdoor scenarios. Indoor scenarios and general development continue to benefit greatly from the LPE estimator.

To switch back to the previous default, set SYS_MC_EST_GROUP to 1. To use EKF2, set SYS_MC_EST_GROUP to 2.

Most notable changes / improvements:

  • EKF2 default estimator
  • STM32F7 support added
  • Crazyflie support added
  • Parrot Bebop 2 support added
  • Log streaming via Wifi to the ground and straight to the cloud
  • New log analysis tool with real-time zoomable plots (logs.px4.io)
