I just wanted to say that I did get the cc2531 sniffer Dongle streaming packets after trial and error cc2531, the cc2531 uses the older packet monitor and not the #2. I set it up on a Windows 7. I was not sure if it was only to run using XP but use the older Sniffer program , it worked fantastic.
Has any on had trouble with win8 or 10 using the cc2531?
Another tangent research !!
