5.8.2

EnablePermanentState command

The command configures the NDEF file to the ReadOnly or to the WriteOnly State.

This command can update the right access to the NDEF file by writing into the EEPROM. In

this case, the response timing will be around 6 ms.

Table 43

defines the EnablePermanentState requirement command.

Table 44

defines the R-APDU of the EnablePermanentState command.
