LRIxK command functions

This chapter describes the specific LRIxK layer functions.

LRIxK_Kill function

This function sends, through the CR95HF, a kill command to the unique contactless tag

designated by its UID and belonging to the LRIxK family. On receiving the kill command, the

contactless tag compares the kill code added to the command and checks if it matches with

the kill code previously written into the code. The contactless tag answers to the command

before being deactivated.

LRIxK_Write_Kill function

This function sends, through the CR95HF, a write kill command to an LRIxK contactless tag

present in the RF field or designated by its UID. The kill code provided is transmitted to the

contactless tag and will be required to deactivate the LRIxK product.

Note:

A lock kill command is necessary after this command to protect the kill code.

Table 108.

LRIxK_Kill function description

Prototype

u8 LRIXK_Kill(ISO15693_Tag* MyTag, const u8

Request_flags, const u8* Tag_UID, const u8*

Kill_Code);

Input parameter

Request_flags: option flag to indicate the parameters to use for the flag

response and if UID is present (addressed).

Tag_UID: pointer on the UID of the tag.

Kill_Code: kill code to compare with the one inside the contactless tag in order

to perform the kill command.

Output parameter

MyTag: pointer on the structure that contains the tag response

Return parameter

LRIxK_ERROR_CODE: The command failed. Either there is no tag or the tag

did not manage to perform the request.

LRIxK_ERROR_REQUEST_FLAGS_CODE: The inventory flag is set.

LRIxK_COMMAND_SUCCESS_CODE: The tag answered the command.

LRIxK_Write_Kill function description

Prototype

u8 LRIxK_Write_Kill(ISO15693_Tag* MyTag, u8

Request_flags, u8* Tag_UID, u8* Kill_Code);

Input parameter

Request_flags: option flag to indicate the parameters to use for the flag

response and if UID is present (addressed).

Tag_UID: pointer on the UID of the tag.

Kill_Code: kill code to write into the contactless tag memory.

Output parameter

MyTag: pointer on the structure that contains the tag response

Return parameter

LRIxK_ERROR_CODE: The command failed. Either there is no tag or the tag

did not manage to perform the request.

LRIxK_ERROR_REQUEST_FLAGS_CODE: The inventory flag is set.

LRIxK_COMMAND_SUCCESS_CODE: The tag answered the command.
