WiFi SD card?

I'm pretty new to everything but I'm also fairly savvy with technology. I'm certain at least some of you have tried to use a WiFi SD card in your machines and I'm wondering how well that has worked.
I actually have no experience with wifi SD cards as the full size sd cards where somewhat obsolete by the time that tech came around. I'm also wondering what the typical size of a CPAP SD card is and whether or not a micro SD adapter works with it.
Being so new I'm not feeling quite brave enough to test all of this out on my own machine so I would greatly appreciate input from anyone with experience.
Thank you

I use the Toshiba FlashAir w-04 16GB in my ResMed AS 10, and I love it.

A typical SD Card is 2 GB so the FlashAir is well above the required capacity.

Some considerations:

• The older w-03 cards allegedly work, but are finicky
• There are other WIFi SD card brands, though I haven't heard of anyone having success with them.
• Your CPAP has to be fairly close to your router. Mines about 30 feet.
• You will need some support software to transfer the data. FlashPAP or SleepMaster.

There's a couple links here: https://sleep.tnet.com/equipment The ssl cert has expired, and the guy that was a regular here hasn't responded to get it fixed, so you'll have to add a security exception, but if you're savvy, you know how to do that

I use Toshiba FlashAir cards as they are compatible with Flashpap A java app to copy the files to my PC other cards are availiable but the software is built for the Toshiba cards

Thanks for the info, folks. I ordered a 16 Gb 04 Toshiba card. My machine sits across the house from my router but if I have any problems I can just set up a portable AP to connect to it.
I'm still working out how to read all of the info that comes from my CPAP machine. I'm not in a big hurry to go messing around with things. My first month appointment isn't until the 6th of December so I think I'll wait until after that to even look at making my own adjustments.
I certainly feel better with treatment but I feel like I could do much better still. I still run out of steam pretty early in the day and I still sleep about 12 hours on my days off before I feel fully rested. Anyway with the way I like to tinker with things I'm actually pretty excited to learn more about this and really get into it.

Start with the basics - as you arise each day, take a quick look at the night's AHI and leak level. https://www.youtube.com/watch?v=Khaalmlt5bY

So I got the card, I got it to connect, and I got everything to work except the file transfer fails most of the way through. It will always get above 50% though sometimes it's 60 some and sometimes its more than 80%. I always get the "Connection has timed out" message.

The first thing to do is rule out a distance problem. How far away from your router is your device?

Move the device closer to your router. Actually it doesn't have to be your CPAP device, it can be any device that has an SD Card and is powered on.

If the transfer is successful, then it's likely a distance problem.

You can also try switching your transfer program. Switch from FlashPap to SleepMaster or vice versa.

I actually had to rule that out pretty early on. The area I live is something of a radio sinkhole. WiFi signals (along with any other radio signals) don't get the range that they should here. To solve this I set up a WiFi repeater only a few feet from my bed. I also tried the card while it was plugged into my computer very near my router and it behaved the same way.

Here is the FlashAir developers documentation that describes the config options.
https://www.flashair-developers.com/en/ ... pi/config/

Two considerations to change in your CONFIG are:
Noise Cancel
Set it to 2, improves connection at the cost of decreased range.
NOISE_CANCEL=2

Station Retry Count
Set to 0, unlimited retry counts
STA_RETRY_CT=0

Be aware you might need to reenter your Routers passphrase whenever you make changes to the CONFIG

You didn't indicate which client you're using or if you've tried both.

I have noise cancelling set to 2. It didn't connect at all otherwise. But I haven't tried the retry count setting.
I'm using FlashPAP but I've been modifying the settings text file directly.
I couldn't get SleepMaster to work. I couldn't get it to write settings and when I try to make it scan the network it just picks up my Raspberry pi for some reason.
Another thing I only just now considered is that perhaps the card is too close to the WiFi access point. I have no previous experience with these wireless SD cards so I don't know if they are finicky about that.

You've done all that I did when I was first setting mine up. I'll just throw out some random ideas. Forgive me if some of the suggestions are overly obvious, sometimes we forget the obvious.

I set up my FlashAir as a static IP, instead of DHCP. I just prefer to know and remember the address when trouble shooting.

Are you able to ping it consistantly? I find my first response is slow or times out but then it's pretty reliable after that.

Are you able to browse to it? You should be able enter the IP address into a browser and traverse the file system.

Have you used it for at least an evening and have valid data? I've got the same ResMed and see the following files and directories at the root (from the browser).
STR.edf, Journal.dat, Identification.tgt, Identification.crc, DATALOG, SETTINGS, DCIM

When I was first setting mine up, I struggled getting it to work with FlashPap as well. I then used SleepMaster. It was a battle as well.

Consider, SleepMaster again, turn off your pi during trouble shooting. Maybe set your FlashAir to a lower IP so it is found first.

I feel like this is a really obvious problem that I'm just not seeing so your help is greatly appreciated.
I have the card on a reserved IP on my router. 1.107 so it's very low as my DHCP range starts at 100.
I haven't tried to ping it unless it's not communicating otherwise so perhaps I should try while it does work just to see what kind of latencies I get.
I am able to access it through a browser and have all of the same files as you listed except DCIM. That folder I assumed was preinstalled on the card as its intended use is for a digital camera so I deleted it.
The Raspberry pi is at a much higher IP (1.138). I'd prefer not to turn it off as it's an integral part of my network. It runs an ad blocking DNS filter but aside from coming up in network scans it shouldn't interfer with this as it only receives DNS requests for addresses outside of my network.

Running out of ideas here/

On your computer, take a look at FlashPAP's target directory, compare what (if any files) are being transferred. Compare them to the files on the FlashAir.

Do you have proper privileges to the target directory?

Any Anti-virus or Firewall getting in the way? Can you temporarily disable or create exceptions?

I'll look at that when I get home from work and let you know what I find out. Thank you for your help.
