The Hardware Support Package for Parrot Minidrones is not Logging Data.

Whenever I run one of the parrot examples, the code will compile and run successfully, but droneFlight.txt (the flight log) will not download. Instead the app will read “FTP error 257.” The code “257” does not map to an error code but instead a response for a properly created directory. After manually checking with FTP in command prompt, I confirmed that droneFlight.txt does exist.

Additionally, the MAT file does not always generate despite datalogging being enabled. Nor does the file download when it does generate, also confirmed through querying the drone manually.

Through manual queries, it was demonstrated to be possible to download files from the drone, but only at file sizes far smaller than the MAT file of droneFlight.txt.

Hello Terence,

Can you tell me the output of the following commands on your MATLAB Command Window? I just need to check what version of MATLAB (along with the MATLAB update) and the support package that you are using:

>> ver
>> matlabshared.supportpkg.getInstalled

Thank you for responding, the response I recieved was:

>> ver
