As an application developer I not always have a need to observe protocol traffic as it happens on the air. So for reverse engineering BLE protocols (especially between IoT devices and their apps) I've usually found my Android phone with developer mode and Bluetooth HCI snoop logging enabled to be very convenient. Wireshark can read the files my phone spits out and because I see the unencrypted packets when captured directly off the HCI it's very easy to work with.
