FlashAir card and changing SSID

[todivefor]

I have a Flashair card I use with my Dreamstation II. I have been running it for several years, however the FlashPAP/ Sleepmaster setup drives me nuts. I wrote directions on how to make this work, so did others. I found 

"Using a FlashAir 64GB SD card with a ResMed AirSense 10 AutoSet on a Mac"

article to be the best written.

I travel between two places where the networks have different SSIDs. At the 2nd location, I would just change the network SSID to that of the 1st location, download the data using either Sleepmaster / FlashPap, and the return the SSID to that of 1st. This year, I decided how difficult could it be to change the Flashair configuration to match the SSID. It turned out to be a PIA. I eventually got it working again with FlashPAP working, but Sleepmaster not. That's fine, someday I'll sit down and figure out what is wrong with Sleepmaster. I have returned to location 1 and now need to reconfigure the Flashair card for this SSID. Has anyone done this? I just want to configure Flashair / FlashPAP with my 1st location SSID. Simple?

I have not needed to do this, but thought I'd offer a suggestion.  Create 2 CONFIG files, one configured with the SSID and password for location #1 and the second setup for location #2 for its SSID/password.  You will name them something like CONFIG1.txt and CONFIG2.txt.  Save them in the FlashAir's SD_WLAN directory.   Whenever you change locations, open this directory, delete the CONFIG file, and copy/paste the desired location's file within the directory.  Now, rename the copy to "CONFIG" and you're good to go.

EDIT:  I just went back and reread your original post.  Stupid me didn't pick up on the verbiage, "on a Mac" . . .  duh!  I will research the Mac's code for doing the same thing and get back to you.

Update to my previous post...
Here are two batch files that you store in the SD_WLAN directory too.  I used the example filename in my post above for this example.

Location1.bat:

Code:

del CONFIG
copy Location1.txt CONFIG

Location2.bat:

Code:

del CONFIG
copy Location2.txt CONFIG

All you have to do is double-click on one of the batch files to reset the CONFIG file to the parameters for either network.


Mac/Linux version:
Location1.sh:

Code:

#!/bin/sh
rm -rf CONFIG
cp Location1.txt CONFIG

Location2.sh:

Code:

#!/bin/sh
rm -rf CONFIG
cp Location2.txt CONFIG

After creating these files, set them to be executable.

That's my plan going forward. Should have started that the first time I changed the config file 5 mos. ago. Stupid me!

Thanks Red.

I'm wondering if there is more to it than that? Is something written in the FlashAir partition? So I am wondering if I have to run the FlashAirTool.app to change the SSID and then change the config file? Hope I don't have to do a full INIT on it?

The easiest way is to insert the FlashAir in your PC, change the CONFIG file parameters, remove it, and insert it in the Resmed. The only caveat would be if the 2 networks are on different IP ranges. Then you would need 2 different FlashPAP or Sleepmaster profiles.

Nothing is now working.

Let me explain again and tell you what I have done.

I have 2 networks with different SSIDS. Let's say location Home with SSID=loactionHomeNet, and location Away with SSID=locationAwayNet. Everything else is the same, ie network password and IP address for FlashAir. In the past when I wanted to download my data, I would log onto the router, change the SSID from locationAwayNet to locationHomeNet, download the CPAP data with FlashPAP, and then change the SSID back to locationAwayNet.

I changed my FlashSir setup to locationAwayNet by basically starting over ie erase and start the whole setup from scratch. I last downloaded my data at my away location successfully.

Now, at home of course my FlashAir card is not recognized. I put my sdcard (SDDISK) into my computer. I duplicated the CONFIG and user files in the SD_WLAN directory. I named one of the duplicated files AWAY_CONFIG and the other AWAY_user. I edited the CONFIG file and changed APPSSID=locationHomeNet,
APPNETWORKKEY=networkpassword (from ***************). I made the same changes in user file. I ejected and remounted SDDISK. FlashPAP can't find. APPNETWORKKEY=networkpassword remains visible not ***************. I tried running flashairtool.app and get the "Check the FlashAir version ..." message, which I can't get around.

I am about to erase and start over, but there must be something I am missing? There must be an easier way?

EDIT: FWIW - ? (192.168.1.220) at (incomplete) on en4 ifscope [ethernet] (from arp -a)

The FlashAir only negotiates a connection to a Wi-Fi network at bootup. If you change the SSID, then it will not see the card until you reboot the FlashAir.

How do you reboot the FlashAir? I thought ejecting and remounting rebooted the card.

That's it! You got that step down.
