Hi folks,
I was testing some ultralight tags.. and apparently, cascade level 2 is not initiated correctly. I did a quick check of the code of the ReaderIso14443a function, and I guess Ultralight is not handled correctly. In the datasheet, it's stated that the tag responses with [88, the 1st 3 bytes of its UID, and 1 byte BCC] to level1 anti-collision. After that, the reader sends level1 select [93 70], and the tag responses with [04 00]. The reader then initiates level2 anti-collision [95 20] followed by level2 select [95 70].
However, in the implementation, and in response to level1 select, the code expects the tag's ID. So, is there something wrong with the implementation? or it's not supposed to support ultralight tags?
BTW, I am referring to the plain Ultralight..NOT Ultralight C.
Best

Okay!! This is fixed in the latest revision. Where do you guys announce that?

Major changes generally get posted on the discussion board, but you can always monitor the SVN repo:

Is there anyway to dump the contents of an ultralight card? They don't seem to use any encryption, but I haven't found a way to use the PM3 to read even a block of an ultralight. Thanks
