Jeff, sorry to hear about the trouble. We are actually working to bring DroneBlocks Code functionality into the new version of our Desktop app. But I would like to help you troubleshoot what’s going on. For starters, can you install the DroneBlocks version discussed here:
I’d like to see if you can get that working. If you can then it tells me there’s a potential issue with the DroneBlocks Code build. If you still have the same problem/error then it tells me that there may be an issue with your machine. Perhaps a firewall could be blocking a port that we use to communicate with Tello. Let us know what you find out and we can take it from there.
