The length of Authentication cryptogram in the response of FAST authentication

I'm using Aqara A100 pro, and according to the trace that I sniffed, the length of the cryptogram is 16 (0x10). Here is an example:

I am not sure if there are different versions of HomeKey.
Hello!
Going to re-check the info on my side in a couple of hours. Also have the A100 (ZigBee), should not be different.
BTW. Accepted your PR.
BTW X2. If possible, would be great if you could also add a full text trace into the resources folder, going to do the same later today when I get back.
Regarding the protocol version.
A HomeKey applet on device reports two versions - 1.0 and 2.0;
My global Aqara a100 requests version 2.0. I wonder if 1.0 is used at all. Seems to me that the only lock older than an Aqara one is the Schlage encode plus, it might be using the older version, although I don't have the device to confirm.
