connected: False, packets: 2695, missed: 0

If you started wireshark you're getting avdvertising packets in. Now youll want to probably sniff some other device connecting to the device you're sniffing. Kick off that connection, and watch for connected: False to turn to connected: True

Catching a connect can take many attempts, keep trying.
