>>What kind of card do you have?
All of them.
. At least any I can find, that are not ruled out by inherent limitations like the eyefi card.
The Toshiba is a nice card, but it turns out it requires certain files to exist on the card. ResMed machines don't allow for extra files, and if you try to hide them it still doesn't work. I have been able to create a special hidden partition of files that works with ResMed, but the cards like the Toshiba that require their own files then don't know where to look for them so it breaks the WiFi functionality.
It would help everyone if there were one card that worked for all devices. For one, the more time you spend supporting and validating different products, the less time you get to create useful functionality.
Another concern is that even if Phillips can be made to work today, if this becomes popular what's to prevent them from trying to lock it down like ResMed does? Solving this problem for ResMed means it will be more difficult for anyone to deny us the right to use our own machines as we see fit.
One option I'm looking at is modifying the firmware of the WiFi cards. This would solve the problem and also provide lots of new possible features. Most of the time it's not possible to just buy electronics off the shelf and start adding your own firmware functionality, but it may be possible in this case.
Independently of all this, probably the next biggest obstacle is finding out how often our machines allow the SD cards to have power. Should know the answer to that soon...
This is cool, I'm going to be watching this thread with considerable interest.
What kind of card do you have? I'm looking at a Toshiba FlashAir 8GB which claims to be fully functional and transparent to the device. Two things are holding me back. One is the fact that I'd need to transfer the data using a "browser tool". It would be cooler if I could map it to a drive and forget about it (failing that I'd imagine that there might be a way to run a batch job to fetch it every day or so). The other issue is that I'm not entirely sure I want to spend $42 pimping my cpap. I will concede that if it saves the wear and tear on my card slot it could be cheaper than a repair bill down the road. I can just see my DME grumbling because of my excessive use of the efficacy data.
