Low download speed MAVFTP #874
Comments
Yes, speed is low because FTP plugin only implements file like operations. E.g. mavros ftp to get each 230 byte chunk send request message, then wait response. All that done by 255-byte long message.

Hm, in theory smaller packets of v2 should give some speed up. Can you use wireshark to extract msgid 110? |
This is somewhat also a duplicate of #686. I'm closing it so it can be continued there instead. |
Issue details
Hello, I download log-files through mavftp, but speed does not rise more than 36KB/s. PX4 connect via USB. Change chunk size does not give a result. If I download logs in QGC, connected through gsc_bridge, speed rise to 300KB/s. How I can accelerate download with mavftp?
