532 command

const (

Mifare command

Variables

var WakeUp = []byte{0x55, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00}

WakeUp When the host controller sends a command to the PN532 on the HSU link in order to exit from Power Down mode, the PN532 needs some delay to be fully operational. Either send a command with large preamble containing dummy data Or send first a 0x55 dummy byte and wait for the waking up delay before sending the command frame.
