sure only $375 and you need a data server running to catch the data when the unit auto sends it at a per set time. that is a very good solution for the home user. I was working on something a tad less expensive and way more convenient. something more user friendly.

BTW Sludge, if we are going to work together we should connect off forum. I have free phone calling and could call you, but I am fairly sure your not open to that, unless it is a burner phone, and even then I would doubt it. I would also guess your not into sending me by PM your email address as well, but I thought you may be open to a burner email address, some hot mail or equally disposable email service account. if so would you send me my PM your new burner email address so I can connect with you, phone works better for me, but I am sure you do not give a hoot about that, put am hoping you may surprise me.

thanks
Stan

I think many of your are not thinking of the potential applications of a wireless network connectivity for CPAP. 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! I think this is a great idea, though retrofitting the current gen CPAP may not be of interest to many of us I would be shocked if the next generation of machine did not include network capabilities built it.

I heard they do not work, the resmed machines rejects using them.
I would love to be wrong.

would be great if they did work

I had no idea, thanks sleep wrangler!!

It would cost $35 @ Amazon to find out.

Personally?

I don't want my private medical data going through a not very secure wireless web connection just to save me the effort of removing an SD card and sticking it in my computer.

I also don't want my doctor accessing my CPAP directly through a wireless device: If the doc can read my data, then he can also send instructions to my machine on the settings. And there have been people here who have found that when the DME changes settings through the wireless modem (or by writing to the SD card), then going into the clinical menu no longer works for changing the settings back to what the user WANTS them to be.

Thank you for pointing that out! I had no idea the DME would be able to change the settings. Even though I am a newbie, I know I DON"T want them to be able to do that. So thank you!!!

I think you misunderstand how a wifi network would work. It would be as secure as your wifi in your home now, encrypted so that nobody without a password to access your modem would be able to see your data. 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. He would not be able to access settings on your machine, the capability to do so through an sd card would even be removed, all he could do is see your data and/or download it if you allowed him to. 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.

I did say the wireless unit I was doing would NOT have a write option. so your doc would have to be close to your house or be a hacker to hack past your router to be able to even look at your files, with the adapter being read only he could NEVER change any or your setting. the resmed machine will have full access so it could save setting YOU put in as well as data it wants to save to the chip.

I hope that clears thing up

as for medical records being available, it is only your breathing data, no name or anything to identify you, what would or could anyone do with the info if they did get it? there is nothing to see, your breathing info is of no use or interest to anyone but you and your doc, and the hackers would need to know what program to use to even open the data to look at it. I do not see the problem here.

I looked around at what other people had tried with those wireless SD cards and found a couple things:

Most are designed to create a wireless hotspot that you connect to in order to download the data. We would want the card to connect as a client to our existing network with our computers so we could pull the data directly to the software. I found instructions on how to do that with the Flash Air, but not for the EyeFi yet.

The software on the cards doesn't include an SMB server, which means you can't directly map a drive letter to it that you could import from in SleepyHead. I figured I'd have to either find a way to add a SMB server, add FTP server functionality and use a program to mount the FTP location as a drive letter for Sleepyhead, or write a program that uses HTTP GET requests to automatically download the files to a local directory and import them to sleepyhead from there.

The cards require power to join the wireless network and upload data. I haven't been able to find data on if the S9 and PRS1 machines supply constant power to the SD slot or not.

Finally, I don't know about the PRS1 machines, but the S9 machines are very picky about the format of the card and not having any other files present.

Apparently the FlashAir uses to run the OS BusyBox and a few people have been playing with custom firmware builds to make it do other things. 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 may also find this interesting:

Activating the semi built-in telnet and ftp deamons on a Transcend WiFi SD card

Recently I was lucky to come across one of Transcends WiFi enabled SD memory cards. Why lucky? Because they recently turned out to be somewhat hackable. There are some recipes on the net on how to get onto the embedded system; I expect some free and alternative firmware to become available soon (but I do not know anything, just estimating!).

What is it about
Transcend produces SD memory cards with a special feature: Wireless network connections. Meaning: Within the size of an average SD card, there is not only 32 GB of flash memory but also an embeded system (which is running some linux) and a wireless network module. All within a normal-sized SD card. Original purpose is equipping a camera with this card to access taken pictures even faster. There exist some applications for iOS or Android devices to use them as a quick preview. For lame PC users (such as myself), there is a somewhat (sorry, there is no friendly synonym) crappy web interface. I would really like to use the thing from my computer without any crappy "app" or http interface. I would prefer a classic network protocol originally designed for file tansfer (yeah, I know, HTTP ... but no). Say, NFS, SMB/CIFS, or (if nothing else is available) FTP. Please don't get me wrong, I am curious and all that stuff, but I do not need to have shell access. Though it would be cool.
Some googling later, I found a very elegant way of invoking a telnet server on that embedded system in the mikrocontroller.net forums (link on the bottom). Three minutes later, I telnetted into my SD card (a somewhat interesting feeling to have a shell on something small enough to swallow it). And some tests later, there was my FTP server.
The way was so easy, I just had to write this article. Here is the howto: Take the SD. Put it into a SD card reader and mount the file system. Then, create a file named autorun.sh in the root directory of the card and drop the following lines into it: telnetd -l /bin/sh &
tcpsvd -E 0.0.0.0 21 ftpd -w /mnt/sd/ &

The file is processed on startup and there should be a telnet and a ftp server running.
Caution: There is no login procedure to both, meaning the WPA key of the card (when in AP mode) is the only thing preventing other people from accessing both the system using telnet and the files using ftp.

Other Resources
•http://www.mikrocontroller.net/topic/303547, this is where I stumbled across the autorun.sh.
•http://haxit.blogspot.de/2013/08/hackin ... cards.html, pobably the first one to publish about the hackability of the WiFi SD card.
