LAUNCHXL-CC1352P: Smart RF Sniffer received packets malformed in Wireshark

Jonas Rosenberger

Hello,

my try to capture Wi-SUN packets using the TI Smart RF Sniffer 2 and my CC1352P1 Launchpad module. However the resulting packets I receive are all malformed.

I found the discussion here and saw someone had the same problem as me, but the problem is not resolved yet. So I hope someone might help me here.

(I followed all guides and the screenshots provided in the related thread look the same as mine).

Best,

Jonas

Hi Jonas,

I think the problem with BAD FCS come from "FCS format" when we choose TICC 24xx or CRC 16. So, CRC-32 is the right one

I just changed it and it worked. I spend so much time fixing this.

Thank you so much!
