Hi,
 
i am trying erase the content (memorybank user, memorybank epc) of a tag with SDK Zebra and reader FX8500, but i can not, because always i receive this exception: RFID_ACCESS_TAG_BLOCK_ERASE_FAILED
 
 
I am following the steps indicates in: https://www.zebra.com/content/dam/zebra_new_ia/en-us/manuals/rfid/rfd85…; (page 89):
 
Block-Erase
 
The application can call RFID_BlockErase to erase the contents of a tag.
 
// Block Erase
 
String tagId = "1234ABCD00000000000025B1";
 
TagAccess tagAccess = new TagAccess();
 
TagAccess.BlockEraseAccessParams blockEraseAccessParams = tagAccess.new
 
BlockEraseAccessParams();
 
blockEraseAccessParams.setAccessPassword(0);
 
blockEraseAccessParams.setMemoryBank(MEMORY_BANK.MEMORY_BANK_USER); // user memory bank
 
blockEraseAccessParams.setByteOffset(0); // start erasing from offset 0
 
blockEraseAccessParams.setByteCount(16); // number of bytes to erase
 
reader.Actions.TagAccess.blockEraseWait(tagId, blockEraseAccessParams, null);
 
First i'm trying delete the user memory without success.
In line: blockEraseAccessParams.setAccessPassword(0);
what password I must indicate? the actual password or directly "0" like the example?
 
Someone have this function implemented and working?
 
Can someone help me? What am I doing bad? or What is the problem?
 
 
Thanks in advance
