Kindle 3G vs Wifi (downloading asleep, Calibre)

[jmochemd]

Hi all,

I have a Kindles 3 Wifi and my wife has the combination Wifi/3G. Both Special Offers. I like using Calibre to fetch and serve my news wirelessly daily. My Windows 7 scheduler does a nice job of collecting everything at about 5-6am in time for me head out for work. My concern is that I often do not turn the Kindle on before I leave and the next thing I know is that none of the news has wirelessly sent and I am not near a wifi connection (at least one I can connect to in NYC). Before I got the wifi version I had the 3G/Wifi version for several days. I am convinced that the 3G/Wifi downloads more frequently (via wifi that is) from my router and email while asleep. Meaning I believe the 3G whispernet notifies my Kindle that it has some messages over the free.kindle.net, wakes the Kindle, and the device pulls from wifi. The wifi Kindle can also download data while alseep albeit I believe much less frequently--hence the numerous reports of Wifi only Kindles updating overnight. This is my theory. Does anyone have any experience? I do not have access to my wife's 3G/Wifi Kindle at the moment to test. I just want my Kindle to update regularly without turning it on. I know I am getting spoiled but why not--that's how our tech keeps getting better. Thanks!

I do think wireless wakes up every so often (every hour or two?). But that's an unverified assumption for me, so I'm running a little experiment:

- put kindle to sleep
- send content to kindle
- go to my Manage Your Kindle page to verify delivery is 'pending'
- refresh MYK page every so often to see if it delivers

Obviously I'm stuck on step #4 at least until 'enough' time passes. Will try to report results later, assuming I can stop myself from waking Kindle up to read something...

Of course just turning on Kindle will initiate check for updates/downloads, but the question has to be whether you can count on delivery happening after a certain period of time even without doing that. I'm curious to know.

It seemed to work. After an hour or so MYK showed the items no longer pending, and when I turned Kindle on, it had the items (the item list just needed to refresh, but it had not yet restored wifi connection.

...er...i believe you neglected to turn off the wifi before initiating the sleep step.

I would like to hear if any 3G/Wifi users were able to receive waiting documents sent to their free account while Kindle was asleep, wireless on of course. Thanks!
