For Scratch, you also need the Tello extension.

The zip file also includes the WIFI "API" documentation. Looks like someone threw it together over their lunch hour . . . hopefully it expands over time.

Personally, this is one of the things I'm looking forward to most with the Tello.

Thanks for adding that extension.
I like what DroneBlocks does as well. A bit pricey, however it is the only app that I can find that’s worth checking out.
It will be interesting to see the first to come up with some great missions.

This vid somewhat shows you the process of installing on a Mac.
Kind of cool I suppose.

Thanks guys! I downloaded the program, docs and extension. This little guy looks like it will be fun.

There is a bug in the current firmware that prevents Scratch working that well. Ryze are aware of the issue and are working on a fix.

What I found was that when it walked through a short piece of code that had any forward x, backward, rotate etc commands it would stop executing and you would have to start over to get it to land.

It does look very very promising however.

DJI shipped mine from China Friday and it arrived in Chicago Monday AM. Though you can find them in stock at some Walmart stores even now.

We put together a better Scratch How to Guide for all you folks, see attached.

Thanks for guide - works perfectly. Im finding if i do a 'fly forward with distance x" post 'take off', it doesnt accept these commands. If I do them manually/one by one, all seems ok, but linking in a sequence crashes/fails. Any one else same exp?

It sounds like you need to put in a delay after takeoff before sending the forward x command. I was scripting and found that I needed a 5 second delay. But your cm may vary.

Hello. I have a Tello drone and I try to program it with Scratch. However, when i try to node Tello.js, it throws such an error and stops:

node:events:306
throw er; // Unhandled ‘error’ event
^

Error [ERR_STREAM_WRITE_AFTER_END]: write after end

What should I do to fix that? I did everything correctly. My OS is Windows 10.
