Hey guys i recently purchased a Tello and its just Tello, not EDU or Robotmaster, there are some functions when I mess around with the Tello library that I find not working: set_video_direction, set_fps... etc, and I realize I am probably using the old firmware, so I try to update the newest firmware but my phone app keeps showing me it is already the latest version. Does that mean regular Tello can not compile these functions? Since I really need that bottom camera for navigation. Could anyone hold a regular tello run this code and let me know how did it go? Thanks
