Gravity calibration basically calibrates the motors for little changes in output power over the motor's lifetime (or changes in props due to nicks and dents, or a prop change, taking off prop guards, adding a Lego figure on top, etc).oh ok, what exactly does gravity calibration do? I'm hesitant to change anything because the tello is actually hoovering and flying very well...
I recalibrated both again but no change. However... I had a lucky breakI just have to tell you try again to redo the two phases of calibration IMU and Gravity.
Wait for advice from more experienced users of me.
Good luck with your tello!
Glad you got it fixed and Thanks for posting. I'll tuck that little gem back for future reference... just in caseI recalibrated both again but no change. However... I had a lucky break
My iPad wouldn’t connect properly so I reset the Tello (press power for at least 5 seconds). After the reset the firmware version showed as 0.0.0.0
Which meant I was able to run the update again, after which when I flew it was behaving as well as when I first bought it.
I’ve run 2 batteries in the same area, pleased to say no problems.
I’m so pleased to have finally solved it and got my rainy day fun back
I'm still waiting on Ryze support... they ask me to send videos, too. Its over a couple of weeks I've now tried test flying in all the places Tello flew perfectly before... but it can't even auto land without the instability. ONE THING: Remove the prop guards it it flies more or less OK -- another user also experienced this (on the DJI forum) and reported it flew well without guards and horribly with the guards on! Wasn't the update to help it fly better WITH guards??.... hmmm. Let me know if support gives some solid answers - I will, too.Guess I was wrong about recalibration solving the problem. She is now intermittently unstable, just a few times each flight, I’ve also noticed that she climbs when moving forward. See video showing instability, bit difficult to control Tello and video with phone at the same time so all video examples are showing Tello when she should be hovering. Have sent the video to Ryze support, looking forward to their response.
What is the meaning of the "mpry" parameter? I can't find the description in the SDK manual.The most recent firmware of Tello EDU reports this Tello State string:
