I'm not really used to do algorithm reverse engineering, so I need some help It's a SPI communication between a STM and a wireless chip, hopefully the data were correctly acquired by the logic analyser

I guess it's a CRC8, data are fixed length of 18 Bytes

enter image description here

I have already tried reveng without success.

    With almost zero context and a screenshot instead of text, it's unlikely that this question will yield any answers. I'd suggest describing the context a little more (like what you know about the wireless chip) and posting text instead of a picture of text.
