Is it possible to transfer an epub from an Android phone to a Kobo reader not using the Kobo app?
For links, getpocket provides a way: I send the link to add@getpocket.com where I registered my email address and then I can synchronise under Articles on my Kobo reader via wifi.
Another way could be to use a server app for Android I could share my epub with and I could get the file to my Kobo reader via wifi.
Is either of these -- or some other method -- doable between an Android phone and a Kobo reader?
