Oh nooooooooooooo! They have my CPAP data!!! What oh what will I ever do.

You can do with your data whatever the heck you want.

Me? Personally I really am concerned about just how much personal data is gathered both with and without my knowledge on me. It concerns me greatly that someone who wants to can learn far more about me, my health, my movements, and my purchasing history that seems reasonable.

And had my DME insisted on putting a modem on my machine back when I was a newbie, I would have said "No way in Hell." And walked out the door and found a different DME.

I don't really think of my home wifi network as being particularly secure even though it is encrypted and password protected.

There are somethings that I just don't want flying around the internet without my explicit knowledge. And data gathered on me by my machine is one of them. Your mileage may vary.

Your doctor would never have access to your data unless you chose to show it to him by allowing his office access to your data if it is stored on an online server or your phone, just like now where you need to give him access to your sd card.

My doc gets HARD copies of Encore reports or email with PDFs of Encore reports attached. I would NOT give him or his staff physical access to my SD card. And I've felt this way ever since I finished the two compliance checks demanded by my insurance. And on both of those checks, I backed the SD card up to a separate SD card before sending it in so that if there was anything at all fishy about the card after I got it back I would not have to use the fishy one.

It would actually be much more secure than the current sd card approach allowing the user even greater control over what the medical professional can see and do.

No I don't see this. Once the stuff is in the doc's computers, whoever the doc allows access to will be able to see it, same as now.

problem is the resmed units appear to not even like the chip at all, can not even use them for data storage with no WIFI active.

this is very cool info, glad you shared it. I would much rather go that way if resmed will use it then the way I was going.

that is so cool
thanks for sharing that

Instant and silent sync between CPU and CPAP data, ability to store data "in the cloud" for your doc or people here to access, and best of all phone apps that would enable you to look at and analyze your data, even store your data!

Personally I worry that way too much of my personal data is out there "in the cloud" already even though I myself don't put any of it out there.

Not all of us want to analyze everything on our (nonexistent) smart phones.

And storing data? It's backed up on three different computers right now, so why do I need it backed up to the cloud?

Hmm, I hear what you are saying and I certainly respect where you are coming from. However, I am suggesting (based on your responses) that you simply don't understand what networking is all about and maybe once you did understand you might really like it. Security is a much bigger issue than you think. For example, if you have a wifi connected computer in your home with financial data or whatever on it, it is possible for a hacker near your home to gain access to that computer and remotely extract information. Only way to keep your data completely secure is to avoid any internet access to the device it is stored on and have significant encryption methods on that computer. If you have a simple password on your computer and it is connected to a basic wifi setup that is encrypted it is equally secure as adding your cpap machine to your network and storing data on a personal cloud storage system. By the way, I agree about not letting the doc get your sd card - I would never do it either!!

To bad. Might get one anyways just to hack it.

I figured my best shot at making it work would be figuring out how to make a customized FlashAir build that mounted a storage partition that the S9 and PRS1 like, joined existing wireless networks as a client, and created a read-only SMB share that could be mapped to a windows drive letter for sleepyhead to import from. Ultimately, I figured that without an S9 to test with, and with only basic Linux knowledge and programming, if I ever figured it out completely I'd have already gotten to the point where I only checked my sleep data once a week or month anyway.

You won't have time to sleep with all that hacking. Having an SD Card sized HTTP server with WiFi is very cool.

I attributed that to what is discussed in these posts:

It's been awhile since I messed around with the S9 SD card and files, but as you found out the S9 is very particular about how the card is formatted. If I remember correctly there is a directory entry for a journal.dat file. The start cluster for that file is near the end of the card data range. I don't know if the journal.dat file actually exists or not, but the directory entry has to be there and point to a specific place on the card. It's almost impossible to duplicate that entry even with a disk editior like WinHex. And, it may be a calculated figure based on who knows what parameters, kind of like the CRC files. That's all part of Resmed's approach to ensure data integrity from machine to Resscan. Resscan will read an SD card that has had the files written to it with Windows Explorer, but don't change anything about the edf files or the CRC won't match because Resscan does check those.

From what Mac users have said, the S9 won't accept a card that has a strange file added to it like what an iBook wants to put on it.

In the documentation of the FlashAir card it warns you not to format the card with a computer because the files on the card are necessary to make the WIFI system work. I found that interesting but continued by making an image of the FlashAir card and an image of my ResMed card as backups prior to playing. I left the FlashAir files intact and added my existing ResMed files on the FlashAir card in the same file structure as they existed on the ResMed card. Upon inserting it in the S9 I received the SD card not recognized error. My initial guess is that the ResMed machine wants only its files to exist on the card

Putting those two together, it appeared to me that the ResMed machine wants only its files to exist on the card but the WiFi cards store configuration files and other information necessary for their operation on the card where the Resmed machines can see them. I assume a custom firmware would have to be developed to store the data for the card on a hidden partition or something like that in order to get the resmed machines to only see a standard resmed card when they look at it, but since I don't have a Resmed machine and don't really understand embedded linux or the internals of the card well enough to know if that is possible, the idea kind of died there for me.

Yeah, no.

Yes, Bunny Huang (brilliant MIT engineer, author of Hacking the Xbox) was able to hack the controller firmware on a couple of SD cards so putting something together should be doable. Not certain why the configuration is stored in the filesystem other than the software designers thought the functional re-use was pure genius. You also provided links where others have assembled a toolchain which makes the project even more turnkey. This would be an excellent hobby project but for me this feature has no value.

upon further refection and new info I have decided to shut down all open source projects
I am way to old and have to much to risk loosing it all in some law suet or group there of trying to help out others. in today's it could never be the guy that got hurt or killed fault, they go over board looking for someone to blame.
as has been pointed out to me and I was to stupid to get it. now I have, sorry.

Ugh! Ask the survivors of Hurricane Sandy or Katrina. Or perhaps the mudslide survivors. Or an F5 Tornado survivor. Some lost EVERYTHING.

So, I use Google Drive to backup my computer / phone. I'm not nuts about it. But I know that "Stuff Happens!" all too often. I'm not worried about what I can imagine. It's the things that never occurred to me that worry me. And for $10 per month, I get 1TB of storage on Google Drive. That's more than enough to be certain important things are on my computer and in the cloud. Even if I loose my phone and all of my computers, I've not lost all my photos and letters and forms and ...

I am aware of catastrophic loss having lived in tornado alley for much of my life and with relatives in both Louisiana and NJ.

But I'm more worried about corporate data mining/spying in many ways than I am about catastrophic loss. The way I look at it simple: If I do lose everything, I've got (far) bigger worries than restoring my SleepyHead data.

But right now? I really do have a desire to minimize the chances that Google decides to sell my personal data to some organization that does serious data mining. Quite frankly, I don't trust Google all that much. Or MS. Or Apple.

That's more than enough to be certain important things are on my computer and in the cloud. Even if I loose my phone and all of my computers, I've not lost all my photos and letters and forms and ...

Pictures? I can see that as being worth having on the cloud somewhere. Letters? Maybe, maybe not, it really depends on whether I would feel comfortable with a total stranger reading them.

And it's not like I won't ever use the cloud. I do use DropBox a fair amount, including for backing up certain nonsensitive files. But I don't regard anything that I put in my private DropBox folders as genuinely private. And so I'm rather picky about what kind of stuff put there: I'll only put stuff in DropBox that I don't mind risking being seen by snooping eyes (regardless of whether they're corporate, government, or hacker eyes.)
