Hi Long Zhu,
I apologize for a late reply.
1 & 2 - Your configuration looks good.
3 - You can change the Write and Read access rights for the NDEF File to prevent unauthorized changes. These access conditions are mentioned in tables 6-9 of the Data Sheet.
You need to change on the CC file and set the rights of the NDEF file
And please confirm that the offset values are correct according to your URL.
Hope this helps.
Thanks for your reply, the CC file INITIALIZED content is：001720010000FF0406E104010000000506E10500808283000000000000000000，and the CC file configuration is as below, could you tell me which value of the CC file content and configuration will be ok for the permanently lock. One more things I would like to double confirm with you that there is no way to read out the 5 keys in my understanding, Only can change and auth the 5 keys, is it correct？
Hi Long Zhu,
After the NDEF File configuration, you need to change the CC File. If you want to permanently lock the tag (just read), you need to set the Read Access Key to 0E (Free Access), and the other three Access Key to 0F (No Access). If you have this configuration, even with the keys, you can't make the authentication. If you want to be able to authenticate and change some configurations, you should select the needed key number, in the R/W, Write and Change Access Keys.
