Hi, thanks for the quick answer. Serendipity helped me out.
Writing the tag with the serie EM4100
protocol, which I supposed it was the right one according to tech specs (https://www.phidgets.com/?tier=3&catid= ... prodid=555
), returns me an invalid argument error:
Error writing tag: PhidgetException 0x00000015 (Invalid Argument)but
with the PidgetTag
protocol I can write the tag, and then I can read it.
So it's solved, thank you for the hint.
