What did you specify at the QuickReader end for the catalog address?
It should be of the form
http://computer_address:
port/stanza
where
computer_address is your computers name or IP address, and
port is the port you have specified for the Content Server in Calibre. Calibre is not recognising QuickReader as an OPDS compatible device which is why the /stanza part of the URL needs to be present to force the Stanza compatible catalog (which is what QuickReader is looking for) to be used.
Also just to check the obvious (in case it is not
):
- The content server is started at the Calibre end
- The port specified in Calibre is the same as you have specified at the QuickReader end
- The Test Server button in the Calibre Content server setup dialog works (to check it is running and the port is open)
- The books you are trying to download are in ePub format. Calibre will only list in the Content server Stanza compatible catalog book entries that have this format available in Calibre.
