Exact APDU command to set the attestation private key?

[jraynes]

Hello,

In your README you mention a command to set the Attestation Private Key:

/send f0020000#(4cc7cf68911896c8e2f9c8cc2f7f0aa21c6acbba381c109afe9118f6cad90f0b)

When I try to send this command with apdu4j I get an error (both with and without the parentheses):

Can you please provide the exact APDU command to send here? I imagine the #() has an implied meaning but I'm not sure how to translate it.

[antonio-fr]

#() means here the data to provide. Looking at the APDU, the Lc field is missing. You need to add the length of the data command, which is 32 bytes= 20 in hexa.
