I have a question about NFC_writable_NDEF.

Hi, I want to NFC connection. so I'm trying to NFC examples.

But, while i was testing NFC_writable_ndef_msg example I have some trouble.

Following the example, I succeeded in overwriting using NFC Tools App. After that, the original code contents were re-executed and still overwritten records remained.

I thought the overwritten record was in the flash data storage, so I deleted all records using the fds example.

And then, Flasing the Writable example again. after that I again flash the Writable example, but there are still overwritten records. Did I not understand?

Where are the Overwritten Records stored?
When I flash the Original code, I want to delete the Overwritten record.

Thanks.
