hi ,

What is the main difference between ReadBinary() to ExtendedReadBinary() ?

for what i understand is that ExtendedReadBinary() ignore Message length (but still reside in the Memory address).

is this the only difference ?

#m24sr #extendedreadbinary

Hi ,

ReadBinary command only allows to read the NDEF message of the file (limit is given in NDEF message length = 2 first bytes of the file). But this lets unused memory area at the end of the NDEF file.

To be able to read beyond NDEF message, M24SRxx-Y products offer a proprietary command: ExtendedReadBinary command.

This command can read the bytes beyond NDEF message, until the end of the file.

I hope this is clear,

Best regards,

Have a nice day,
