Just updated the firmware on my new Tello and was able to raise the altitude limit; that option wasn’t available with the older version before the update. Thanks to all of you for the info
When you say altitude limit to you mean how high the Tello is capable of flying or how high you can go and still get good visual sensing
I have flown higher than 10 meters but when I do I get the visual sensor warning. If the update somehow increases the effectiveness of the sensor in a way that allows you to go higher with the benefit of the sensor I'd do the update. If it's simply to go higher without the benefit of the sensor I personally wouldn't do the update.
