Hi!
I obtain the error “File does not exist” or “Protocol error” (see class Ftp · MAVSDK Guide result section) for downloading and listing files respectively. In this issue I provided some outputs, if more outputs help I will defintely upload them! File transfer MAVSDK: Protocol Error
For the server I’m using stock ubuntu, but also tried on mac with the same results.
I confirmed the upload files are the correct files written to the expected location (folder of ftp_server, from where I launch the server).
Thanks for your time and quick replies :)!
