Faster transfers #9

Open bbx10 opened 7 years ago

bbx10 commented 7 years ago

I made some changes to increase transfer speeds to the range of 100 - 300 Kbytes/s. Also reduces blocking so ftp can co-exist with other services. Let me know if you want a PR.

great work! thanks. Good timing too, as I just got a esp32 and was going to test the library with it. I'll test out your changes and verify esp32 library as well. (unless someone has already tried it on esp32 and can confirm it works fine...)

SPIFFs for arduino-esp32 is not ready but I will also try it when it is.

The FTP server is faster than expected. wget ftp://esp8266:esp8266@192.168.xxx.yyy/512kb.dat shows 877 KB/s for a 512 KB file.

@bbx10 Congratulations !!! Working flawlessly on the Wemos D1 Mini Pro till the flash got corrupted.

@nailbuster Your original library was corrupting my 16 MB flash, so I'm currently testing @bbx10 changes now on 3 MB of flash. My ESP32 will arrive next week so I can test it if you want.

Well, I'm doing some tests on 3 MB of SPIFFS now, because with 14900866 total bytes of flash, every now and then my files get corrupted after transferring them to SPIFFS. I wish to have some luck this time. You can get some updates on here:

@nailbuster & @bbx10 As SPIFFS on ESP32 is working now I added support for the ESP32 to your FTP server. I merged as well bbx10's changes for speed improvement and reduction for blocking. Tested on my ESP32 dev module with FileZilla.

I added as well a library.json (needs to be adapted though) so that the library can be used with PlatformIO.

See pull request Added ESP32 support, merged bbx10 speed improvement
