How to use the Req_RN direct command (9Fh)

[CShac]

I have successfully read an epc tag, my next step is to issue the the Req_RN command. I hav set the RX lenthg register ready to receive 4 bytes of data and issue the Req_RN command. OIn the occasion that I do receive the expected 4 bytes of data they never seem to be a matching RN and CRC16. Can any one help?

Hello Chris,

since in another thread your are already using the READ command I would assume that you have come by this problem already?

Cheers,

Yes this is now fixed. It seemed to be a timing issue.
