Packet Data Unit that DSD+ didn't decode. No big deal. They come and go across most of my decodings.

Thanks. I was just curious.
This was the only time I've seen that in my event log going back to 2021.

Yeah, it happens from time to time for me. "Good" decoding isn't "perfect" decoding, and all decoding has errors. There is no perfect decoding, otherwise error correction wouldn't need to exist.
