Hello,

I'm using an RFID reader (Feig LRM1002) with 2 different version of the M24LRXX chip :
- M24LR04E(ANT3-M24LR04E)
- M24LR16E(ANT1-M24LR16E and ANT2-M24LR16E)

A problem appear when I scan my tag :

When I send an "Inventory" command there are no problems, I can see both versions of the chip.

The problem appear when I send a "Read or Write Multiple Blocks" command. With the M24LR16E I have an error message : "No Transponder In Reader Field" (it works well with the M24LR04E).
I tried the "Extended Adress Mode" but it didn't change anything.

Do you know what the problem could be ?

For information I use the demo software provided by the reader manufacturer (Feig ISOStart).

I took some screenshot :
