[split] FYSETC SD Wifi - Possible FlashAir Replacement

[Crimson Nape]

It appears that you two are talking past one another. It sounds like one of you is using the FYSETC board and the other is using the EZ-Share SD card. Am I wrong?

[dpackham]

you are correct.  I thought he had a new solution for the  FYSETC card and I was wrong on that.  I am looking for that new code that works with the card.

I thought I'd post this about another WiFi SD player in this arena.  It is the Big Tree Tech (BTT) SD Cloud v1.0.  It can be found on eBay for $10.94 with free shipping from China.  There is an option (+$1.38) to order this card with a micro SD, but I found that it is a 120 MB card. Until this one, I've never seen one that small.  The basic differences between the BTT and the FYSTEC is the BTT is longer and seems to operate in an unmodified Resmed SD slot.  The BTT also doesn't have the USB/SDIO switch.  

There are various firmware packages available for the BTT card that will allow it to act as a ftp server.  Also, available is code to allow for Over The Air (OTA) firmware update.  These packages may work with the FYSTEC as well.  I will be playing with them in the upcoming weeks.   Another slight difference is the developers of the BTT card chose Microsoft's Visual Studio Code (VSCode) and PlatformIO IDE over using Arduino IDE.  Like the Arduino, VSCode and the add-on, PlatformIO, are free.

Here is an image of the front and back of the BTT:

I have uploaded and run the BT software on the FYSETC card.  Ill post more as I use it

I had a major setback  using the BTT card.   The SDIO portion is only setup to be used as an SPI interface (Serial Peripheral Interface).  This little tidbit of information is buried down in their instruction PDF.  I only found out about this after contacting them about the problem.  The replay contained the following link, https://github.com/bigtreetech/BTT-SD-TF...r/Hardware, which had the little disclaimer listed below.

• 2. Scope of application:
  Any SD card interface that communicates via SPI can be plugged
  in and used directly. Such as:
  BIGTREETECH SKR series motherboard 、 GTR motherboard 、
  BIGTREETECH TFT24 V1.1 、 BIGTREETECH TFT35 V3.0 、 BIGTREETECH
  TFT35 E3 V3.0 and so on
  Note: all SD card interfaces that communicate via SDIO mode cannot
  be used; For example: BIGTREETECH TFT35 V2.0!!
  

Bummer!!!  
Everything else about this card works so well and is long enough to fit in the Resmed slot without modification.  It would require some cut-and-jumps that would interfere with the physical constraints.

You know, I'm tempted to just make my own circuit board with a longer SD and install the Fysetc components on it.

I'll send it. I need to do a major cleanup of it first. I have lots of debugs and commented junk in it.  
Plus list the added libraries I used.

Any update on the code posting?  I am eager to NOT spend $10000 on a FLashAir card and use my SD-Wifi....

Hope I am not violating the board etiquette by posting on this old thread. I was wondering if either if you would mind sharing the code. I just got my first machine and cobbled together FYSETC + SD Extension + OSCAR not knowing you all had solved this over a year ago.  My problem is the FYSETC crashes and has to be re-seated every day. Beyond that, it works fine. I suspect it is not getting enough power and am interested in the stability and other low power improvements AlanE mentioned.

Here is where you can send it. Thanks so much!

Hi intrnd! -

As you suspect, the SD port on the CPAP is unable to supply the required power for the FYSTEC card. It will run fine in a PC slot, but not the CPAP's. For this reason, it has become a dead-end project.

I fried the donated board (sorry man - my fault I swore I had it on 5v) and didn't bother buying another so I shelved the project. My A10 is about done anyway. Complaining the motor is at the end of its life, the cell modem no longer connects (all the emotional damage the sleep doctor is going through because they can't spy on me). In fact that whole board with the SD reader is having issues. Next machine will just be the A10 non-big brother edition.

Well, it had a good home while it lasted.
