Hi, is it connecting to the Windows PC as a peripheral? In that case, I'd assume the LL_CONNECTION_UPDATE_REQ packet is sent from the PC and not the nRF. The Softdevice does not support the slave initiated LL connection update procedure (core spec 5.2, Vol. 6, Part B, section 5.1.1)

Hi daviddedwin, thank you for your kindness. This is a screenshot of the sniffing. nRF52 based device is connecting to a Windows OS PC host. A you can see the window offset is 0. Should you need the whole pcap file I'll ask my boss if it is possible to share. Thank you, best regards

You can post the sniffer trace pcap file so it easier to understand.
I assume you are using the nRF52 in the master role and want to use a Window Offset that is different from 0.
You also want to know the implications of having a Window Offset of 0.
