Error when download/cat files using mavftp: IOError [Errno 110] Connection timed out #686
Comments
Flight logs often too big for FTP, also for some reason it is stable only with USB connection (usb on pihxawk - ttyACM%d). Note: FTP is slow, but QGC download implementation twice faster than mavros. |
Where may be the difference @vooon? |
QGC support streaming download, it require only one request message to transfer whole file. I'm not going to implement that mode, just use QGC. |
I think this is a need, given that we offer the FTP possibility on MAVROS. I will look into it and get back with news (and a PR). |
@TSC21 because FTP stable only via USB, and main usage of mavros via TELEMx there no reason to implement that mode, and it is not compatible with current fuse-like interface. So:
|
@vooon as you wish. I think one of the main usages of MAVROS to some people is also use it as a replacement of QGC. Still, we are lacking support for ULog streaming. |
It's a usability thing. File transfer is ridiculously slow over telemetry, and pulling a log of any decent size (10-15 MB) will take too long even with an optimised implementation. Regarding ULog streaming - Yes, it's a nice-to-have, but you can just use |
True. Still, I think it's our wish as MAVROS developers and maintainers to have it full-featured. |
Actually for newer drone i will setup router between tty and mavros. And i don't thinking that mavros is replacement for any GCS, it is set of API to write your autonomous control software. |

So I'm able to open the file, as the main roslaunch mavros window displays:
