I use the Flutter NFC Kit library.
I enter the password and then use: Extended Read Multiple Blocks
"2033XXXXXXXXXXXXXXX00003F00"
Request_flags -> 20
Extended Read Multiple Block -> 33
UID -> XXXXXXXXXXXXXXX
First block number -> 0000
Number of blocks -> 3F00 == decimal 63 blocks (total read 64 blocks)
With this line of code, I read 64 blocks, but if I try to read a larger number of blocks, for example, 128 blocks, passing 80h for Number of blocks, I receive an error message and the blocks are not read.
Is it possible to read more than 64 blocks with smartphones?
