§ brp_Iso14b_Halt()

brp_errcode brp_Iso14b_Halt ( brp_Iso14b_Halt_t  params)

Switch the PICC with the given PUPI serial number into halt state, so that it will not answer to further brp_Iso14b_Request() commands, except when the ReqAll flag parameter of the brp_Iso14b_Request() command is set.

The memory occupied by this PICC's information will also be freed, which makes it is available for future calls of the brp_Iso14b_Request() command. Use this command in order to deactivate some of the PICCs in case the BRP_Iso14b_ErrMem status code has been returned by the last call of brp_Iso14b_Request().

This command only works for PICCs in ready state. For PICCs in active state, theIso14L4.Deselect command should be used instead.

Parameters
[in]paramsStruct with the following fields:
  • protocol used to execute the command
  • PUPI (in) Pseudo-Unique PICC Identifier (PUPI) of the tag that should go into halt mode.
