Please advise me if my usage can be allowed by NT3H1201 device.

I want to reserve some memory area (around 300 byte) of user memory,

So I write NDEF to user memory in  the middle of user memory space like below.


----- User memory (start page)

0x00 0x00 0x00 0x00  // For reserve purpose


0x00 0x00 0x00 0x00  // For reserve purpose

(Actual NDEF data is stored from here)



----- User memory (end page)


With this usage, I noticed that some Android 5.0 or later terminals couldn't read NDEF data.

Do you think that my usage is possible?
