Monitoring data wirelessly

[Crimson Nape]

Using a DHCP assigned address is a very "iffy" thing.  The router can reassign this address to another device.  I've found a more stable communication link to the FlashAir (FA) is by assigning a static address.

I have listed your CONFIG file along with the changes.  The current declarations are marked in green and the changes are in red.
Current File:
DHCP_Enabled=YES  <------ Change This
DNSMODE=0  <------ Change This
DHCP_Enabled=NO
DNSMODE=1
IP_Address=000.000.000.000       ← Change to the fixed IP you want
Subnet_Mask=255.255.255.0        
Default_Gateway=000.000.000.000        ← Change to your router IP
Preferred_DNS_Server=000.000.000.000    ← Change to your router IP
APPMODE=5
WEBDAV=2
CID=02544d535730384731c2ecf27900f101
NOISE_CANCEL=2
APPNETWORKKEY=Replace these ******** with the actual password on each file edit.
APPNAME=flashair
APPSSID=WiFi-Repeater
LOCK=1
APPAUTOTIME=0
CIPATH=/DCIM/100__TSB/FA000001.JPG
UPLOAD=1
VERSION=FA9CAW3AW3.00.00


After the editing, remove and then reinsert your FlashAir back in your computer's SD slot.  It will initialize the FA there.  There isn't anything magical about using the CPAP's SD slot for testing the F-A's communication parameters.   Allow it a minute to come online, then any or all of the following to test it out.  Note: Since I'm not Mac savvy, I don't know the actual names and its layout for the 3rd option below. Just, please go with me on the idea.

• From a terminal, type: ping -c3 FA's IP - You should see a packet response with a time in ms.
  
• From your web browser, enter the FA's IP in the URL box. - You should see it displayed as a webpage.
  
• Open your file explorer, Look under network locations for the FA, or type,  //FA's IP in the find box.
  

I hope this may help.  Please keep us updated.

The problem is solving at the moment: it was a matter of signal strength. I have a new repeater that seems to be far less sensitive than the former. So I placed that one now closer to the CPAP and... hoppa! ...it found the card.

Furthermore, I added a -P parameter to rsync in order to see some progress. And that shows that data transmission is utterly slow! It is building a file list and says 4300 files at this moment, half an hour after I started CopyCPAP!! I don't know whether it is downloading or just counting

Another thing is with the relative addresses for folders. My OSCAR.app is on the Desktop and I saved CopyCPAP there too. So in an earlier trial I saw in Terminal that it could not find OSCAR in /Desktop/Desktop/...

Still waiting, now at 4900 files.
-----------------
UPDATE:
It counted to 5266 and then started downloading 
I guess that will last some hours...

...make it a few days... now xfer#418, to-check=4819/5266

Yeah, the first time rsync runs it can be slow, especially if you have a lot of data on the FlashAir card.  With ~1 year of data on my card it took just under an hour the first time.  The FlashAir WiFi is certainly not the fastest but there is not much we can do about that.

Still, it's a workaround until there is a better solution, or can find a member that is more fluent in AppleScript......

I hate to break it to you, but your nickname is "McJeff".

I fully agree!! 

  It saved us from the evil in Big Mac...

Jeff, how do I clone a FlashAir 16 SD card to have ready as a backup? I have been unsuccessful using the Apple 'Disk Utilities' App to do this. I first formatted the card successfully with MS Dos Fat 32, but even with the format/erase of the card, two of the hidden files were untouched and could not be manually removed. I had to change permissions within my System Preferences to even allow Disk Utilities access so that I could make the FlashAir .dmg file which I saved to my desktop. I still get a "Could not verify Source" error when I try to "Restore" my .dmg "image" to the new FlashAir card. Simply copying all the FlashAir#1 files (including hidden files) to the new FlashAir#2 backup card did not work, because Finder will not allow me to delete all of the FA card's original hidden files. Any suggestions? Thanks

You meant "MacJeff" didn't you?  Being of proper Scottish descent, the "a" makes all the difference.

   Well shoot, I would have voted for the other guy!!!  You walk out of the room to get more coffee and all hell breaks loose around here! 


That's alright Iv'e been called much worse.....   Shhhhh, don't tell anyone!!!

You can create an img (clone) of your SD card like so:

Make a *.img of an SD card:
From Terminal run "diskutil list" and get the disk # of the SD card

to make the img:
sudo dd if=/dev/r<disk#> of=/Users/jeff/NameOfFile.img bs=1m
(sudo dd if=/dev/rdisk2 of=/Users/jeff/flashair.img bs=1m)

to restore img to SD card:
sudo dd if=/Users/jeff/flashair.img of=/dev/rdisk2 bs=1m

using gzip to compress:
sudo dd if=/dev/rdisk2 bs=1m | gzip > /Users/jeff/flashair.gz

gzip to restore to SD card:
gzip -dc /Users/jeff/flashair.gz | sudo dd of=/dev/rdisk2 bs=1m

These original hidden files are the motor behind the FlashAir. They have nothing to do with your CPAP data. Be glad that you couldn't delete them: you would have made a normal SD card of it...
