SRIX4K_SelectChipID command description

Prototype

int8_t SRIX4K_Pcall16(uint8_t*pResponse);

Input parameter

None

Output parameter

pResponse: Pointer to the CR95HF response

Return parameter

RESULTOK: Function is successful. The command is

successfully emitted to a contactless tag.

CR95HF_ERROR_CODE: Function failed. The CR95HF

returns an error code.
