[celevra]

Hi,

i tried the example with these settings

const desfire = {
	key: 'xxxx',
	appId: [0x17],
	keyId: [7],
};

but i only get an error and i can't really tell why, could you guide me in the right direction?

problem solved, it has to be 3 appId's so the example is totally correct, sorry for the inconvenience
