About Pro controller/Joycon LTK error ，ask for help

[HelloRayH]

Hello, I have recently paid attention to the controller of switch, and I have seen a lot of materials worth learning here. Thank you for your contribution.
I'm using USB & Bluetooth analyzer to capture the transactions between PRO controller and switch.
Among them, AB9197A05FD5FF75D11E7704E7723243 bytes behind 81 01 02 should be LTK according to the protocol, and each byte should be XOR AA, but it seems that it is not right ,when I fill these 16 bytes into the data captured by Ellisys Bluetooth Anayzer. What am I wrong with?
I also found a tool get_jc_procon_ltk（(Pair Pro Controller in HOS and Switchroot Android simultaneously. | GBAtemp.net - The Independent Video Game Community https://gbatemp.net/threads/pair-pro-controller-in-hos-and-switchroot-android-simultaneously.600377/)）, but it is based on linux. I don't have a computer in this field, and I don't know anything about the system. Of course, I haven't found the source code of this tool, so it doesn't help me.

I appreciate your help.
