This is true, but the connection request only comes on one channel. The sniffer can be set up to follow an advertiser though, which makes it jump to the next channel in the sequence as soon as the time window for sending a connection request after the advertisment is gone. It picks up connection requests virtually every time in this mode.

Both this and encrypted communication interpretation works a lot better than the commenter above you claims. They've either not tried this sniffer, and are only making claims based on assumptions, or they haven't learned how to use it properly.

It's definitely not as good as commercial sniffer hardware, but it's perfectly fine 90% of the time, and the price is two to three orders of magnitude lower.
