ResMed smart card - any further info?

[Jay Aitchsee]

but ACS reader monitor still says "Card Status Unresponsive" and ATR is empty.

I've never used the reader Monitor App, but it would appear the QuickView diagnostic is a more robust program and it seems to indicate your card and reader are operating normally. Reading the help manual of the Quickview Diagnostic indicates the program will display the ATR Value and the Active Protocol of the Card inserted. Since no ATR is displayed by either the QuickView or the Monitor programs, is it possible this card simply does not answer to reset?

I suspect that these cards (as used by ResMed) are not smart cards at all, but rather are memory cards, such as the ACS SLE5542 and the SLE5528 which could explain the missing ATR, but I don't have the knowledge to say for sure. Maybe you could research this bit. The tech sheets for these cards do say they conform to ISO/IEC 7816 with regard to ATR.

I tried to find something about the SLE-cards, but found very little.
Maybe I try the standards...

Also, I found a windows program that allows me to send commands in hex, and I could read stuff from the card.
Too bad it's a toy-program. I can't copy the read data in hex, nor does it log anything.
I tried to find out about using smart cards in Windows programs, but found very little.

I might be able to write a Linux program to read the data, but figuring out about windows seems more work than
I have time for. Darn. (I'm thinking about SleepyHead...)

Question for you.
IF (big if) you could get SleepyHead to talk to the smart card what information would you hope to glean from it?

Well..another question...do you just like to try to sort through challenges like this as a matter of something that gives you pleasure in getting something done that couldn't be done before?
I know there are people like that and I am to a certain extent but I get a headache when I challenge the brain too much just so I can prove that I can do it.

OK, so you made me dig out my old S8 stuff
Here's a screen shot of the QuickView and it does show the ATR to be 3B 00 with a T=0 protocol, which is probably appropriate for a memory card.

My log, shown below the shot, is essentially the same as yours.

The same that ResScan reads from it.

That I don't really know. Almost 20 years of embedded SW... maybe I'm already addicted to frustration.

[Jay Aitchsee]

Even if you got it to work, ResScan is probably just as good for the S8 anyway, since there is no flow data, etc., that can be displayed in Sleepyhead. My solution was to buy an S9.

But here's the ACR38 Reference Manual, FYI. There's quite a bit about memory cards in it.
