Hello Andreas

First let me tell you that I highly apreciate your effort to make a Arduino library for the PN5180-NFC Module. I have some electronics knowledge, I can understand and adapt/modify an Arduino sketch, but that's all, I'm nowhere near to make a library or something!

So, I just received a module, I have installed your work and... EVRIKA, I can read a few tags!

The problem came when I tried to write to this tag, can you please help with my issue?

Is there some other command to write a block?

Thanks in advance!

Here are the logs from Arduino:
