S10 sdcard, remote wireless data transmission

My new S10 AutoSense came with no sdcard!, but with the built in wireless data link. The data link is not Wifi, it is a built in ATT serviced wireless cell phone like interface. I think the data goes to some central place operated by ResMed and my provider has access to it. For insurance purposes they monitor the compliance data, at least for 3 months. In my case, after that I can turn off the wireless with the Airplane Mode On.

Anybody knows what the max usable capacity of the SDCard for S10? For S9 it was 2GB, even though it would access 4GB (or larger?) card 5 yrs ago. These guys are so cheap not to include an SDCard with the machine It is not easy to find those small capacity 15 yr ago SDCards

Just get the smallest/cheapest SD card that you can get and it will be a lot bigger than you will ever need but those small 2 GB cards are getting scarce (and pricey if found) and it doesn't hurt a thing to have a lot more available on the card than you need.
The last one I got (lost a card) was a cheap Sandisk card at WalMart and it was 8 GB and it works just fine.

If you want to check yourself the data with Sleepyhead, then I would recommend buying a wifi SD card (standard size SD card, with wifi built-in), like a Toshiba FlashAir one.

It will allow you to download the data from the machine to your computer without taking the SD card out repeatedly.

http://sleep.tnet.com/ has a lot of information on this.

FlashPAP is a utility you would need to use to copy the data from the wifi SD card to your local computer, for such data to then be imported into SleepyHead.

I have put flash air cards in both of our machines. It makes it easier to transfer data to my computer, and eliminates the possibility of copying the data to the wrong sleepyhead file. I have sleepyhead programmed to read the data from files on my hard drive with different files for each of us.

Does this method of wireless data transfer still send the info to ResMed? If not, I guess you would want to wait till any compliance issues are past before starting a new SD card.

The SD card type or even lack of doesn't affect the AirSense machine's data transfer to the MyAir ResMed website at all.
The data that gets sent to the ResMed website is the data the machine has stored in its internal memory and that happens no matter what SD card is used or even if no SD card is in place.

So you can do whatever you want short of erasing the machine itself and not have it affect anything that is being sent to ResMed for anything including any compliance use requirements.

The AirSense machine uses cellular data transmission for sending to ResMed website...not WiFi.
The special WiFi cards are used only for the transfer of the data on the SD card to your computer in your house so that you don't have to remove the SD card from the cpap machine to use the available software (which you have on your computer).

So whatever you want to do with the SD card or type of card or even no card...doesn't affect what the machine sends to ResMed via the cellular data transmission.

You implied this So the max S10 uses is also 2GB just like S9?

This is a good idea! The convenience of using this method for me will depend on the range of the wifi built into these cards. What is the typical range? Do they have an external vertical antenna? I have not used one of these cards... If it does not reach where my computer is, it is much easier for me to take the SDCard to the computer Thanks for the suggestion.

On S9, only compliance data was stored inside the machine memeory.. Not all the other details we see in, for example, sleepyhead. I very much doubt in S10, even if they can temporarily store the data in the machine, they would transfer all that over the wireless cell. That is my guess is without a card, only much smaller subset of data (possibly compliance only) is sent over the wireless cell! What is the expert view here?

I don't know for sure what ResMed is supplying or even if they are supplying SD cards now with the AirSense/AirCurve 10 machines.
For all I know they (ResMed) bought a gazillion of those SD cards with 2 GB way back when and when those are used up they will simply supply 4 GB or 8GB or whatever GB cards they can get a good deal on assuming they still put a card in the machine when going out the factory.

BUT....I just checked my SD card that came with my AirSense 10 for Her AutoSet...and it shows a 3.69 GB capacity...so looks like it is a 4 GB card.
I am betting ResMed ran out of 2 GB cards some time back.

I have used less than 400 MB though...so I have tons of room remaininig.

No, the s10 will keep saving data till the card fills up, read the manual.

My computer is located in the den which is located in the front of the house, and the machines are in the back of the house in the bed room. They are able to transmit to my wireless router which is located close to my computer. They are able to communicate through at least three or four walls, depending on the machine location. Once in a while, I will have to go into the bedroom and reseat one of the cards. Other than that, I have had no problems communicating with them. I use Flashpap to communicate with the cards and transfer the data to my computer.

I checked thru the clinician manual in all sections dealing with the sdcard. Sorry I did not see anything to the effect it would use until the card fills up. Could you please help by pointing out which page? Thanks.

I thought I had seen in the past what PR was talking about but I can't find it now. I do think that I remember seeing something somewhere to the effect of what he said though but I don't remember where unless I missed it in the manual somewhere just now. It's late and I am tired and it's possible I missed it.
All I found just now was the 365 day thing.

If you get a reasonable wifi signal where your CPAP machine is located, then it will work. The Toshiba FlashAir cards are able to join an existing wifi network, so the location/distance with your computer does not matter.

They don't have an external antenna so won't work if the signal is weak, they look identical to regular SD cards and the CPAP machine does not know the card has wifi capability.

Page 29 on my copy of the combined airsense manual:

365 days of summary data.

Detailed and high res data "Limited by usage and SD card storage capacity" So, limited by the size of the card.
