pcf7931 writing

Hi everyone,

I've got a pcf7931 of which I know the password.

I can read it with the proxmark rdv2 with the default LF antenna, but I can't write it. I'm pretty sure that all the write parameters are correct.

Could it be an antenna problem or am I using the write command in the wrong way? Meaning should I call it "alone" or "inside" a read?
