      OMG! The protective cap on the camera 😬
      You're right! Just saw it minutes before checking it here. There was no cap on the first drone; it was probably dropped or something, so I did not even feel the need to look for it.
      Thank you, Adrian; sorry for the trouble. Case closed!

      Is it possible to estimate the wind speed?

      Hello @Umut-John,

      The concept of estimating wind speed using a quadcopter is an interesting and complicated problem. We do not provide the software that implements this feature, but there are research papers you can read which discuss this topic. For example, I came across the following publication after a quick google search : https://journals.sagepub.com/doi/full/10.1177/17568293211070824 . I do not know how good this particular approach is (I did not read it in full detail), but this paper explains the key concepts involved in estimating the wind speed using a quadcopter, such as the need for accurate attitude estimation, characterization of air frame drag as function of tilt angle), and the authors propose a Kalman Filter approach which you can investigate.

      Hopefully this gives you a good start - please do some more research!

      Alex

      Still need some troubleshooting on the logs I've posted if anyone in the team have some time. Cheers to all!

      I'm sorry, we do not have any experience with ad-hoc mode. You could try an external wifi module that supports this. If you need to rebuild the kernel, the source code is here
