Koreader > Calibre Wireless Device Connection

Hi,

I've installed Koreader on my Boyue Likebook Mimas and I'm trying to use koreader's wireless connection to Calibre.

I can successfully connect to Calibre from Koreader as long as I don't set a password and send eBooks to the device, but on reconnect Calibre can't see the eBooks I previously transmitted nor sync reading position.

Is this normal behaviour or am I messing something up?
