I have a tag that I'm evaluating for a development project. It incorporates a SL2S2602 ICODE SLIX2 IC. I'm using the NXP TagWriter Android App from Play Store to do my evaluation. I can write a Bluetooth MAC Address to the Bluetooth NDEF record, but there doesn't seem to be a way to lock, write protect or password secure that data. Is that just a limitation of the App?
