How I managed to set up Dropbox cloud sync with KOReader step by step

[remizik]

Hi,

I can't go past the terminal step :

did something change since this thread was posted ? or am I doing something wrong ?

looks like dropbox doesn't like the "-u" parameter

Thanks

Try "curl.exe" instead of curl. Newer Windows/PowerShell has a fake one built in that is compatible with some of the most common cURL commands.

That did it ! Thanks

I'm getting a "access_token" after the curl command, but not a "refresh_token". I've gone through all the steps twice (deleted app between, created new app) and KOReader is not able to access my dropbox.

hi, how do i set Dropbox folder?

[b0dhimind]

I tried setting up a OneDrive WebDAV connection (which works perfectly fine with WinSCP) but fails with Kindle KOReader. I think it has something to do with the refresh token or something... too bad my GBs of books are all on OD. Anyone have any luck with OneDrive?

Following these instructions, I was able to setup DropBox and it does sync (download only).
Too bad two-way sync is not possible (download AND upload including changed modified PDF files and reading sync files).

Looks like I will have to SSH synchronize every now and then.
