Hi,
What exactly is your card reader expecting ?

Example: write to block 40: “00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F” //this is what i send but i want to send for example "hello world" or "data was written"
Successful operation:

when i want to read block of 40 i have to show that :
Example: read block 40 (0x28)

hello i solved the problem thank you all
-
What was it ?
-
it is about send to text data selected block and after take the text data selected block, actually if i show it it will be more understandable. i know it is easy to do but i was forced while converting.
