Updated the code. Fixed several bugs. It also supports the start of a feature where a JSON file containing commands can be sent to the drone. There are still several bugs around the feature that I am working on.
I have been working on a .net core wrapper for the sdk. So far I have tested takeoff and landing but I plan to continue working on it. If anyone here would like to contribute the code can be found here: 8bitbytes/TelloSdkCoreNet
