I've been looking for a solution to sync my ebooks from calibre to my rooted Sony PRS-T1 by WiFi and found it:
Calibre Sync is an app by which it is possible to send ebook from Calibre to your rooted Sony PRS-T1 by WiFi, no cable/USB connection necessary:
https://play.google.com/store/apps/d...engjea.calibre
The problem is that Calibre does not seem to "see" it as Sony Reader when connected by WiFi, instead it shows a connected "wireless device: sydney".
As the consequence it does not populate the library on the device.
Who knows how to "tell" calibre to recognise "sydney" as Sony Reader and use the right plugin for PRS-T1?
