Help with mifare classic 1k card please

[Sarah-1331]

I have a card MIFARE classic 1k and cloned to a magic 2 card works flawless every single time

If I emulate it on the ultra the reader refuses to acknowledge it the rf ID light is flashing I have tried several settings but nothing.

Any pointers

I should point out read and written using CUGUI app and am uptodate with its firm ware

I can read the CU using an android with MCT but the official reader won’t

someone mentioned timing? can this be adjusted at all my the end user?

thanks again

Call the issue something useful, like "Emulation issues with mfc 1k, magic card works fine" or similar, although this is realtime i wouldn't consider an issue tracker a realtime chat...
I think a similar issue was raised before, maybe search the issue tracker beforehand too...
