I am testing your nice BLE utility code and I am trying to receive the advertising packet of event type 4, Scan Response. In testing with your example_ble_scan.py code, I only receive event type 0, 1, 2 and 3. None of the type 4 packets. Is there some way to enable reception of these packets in your code?

If I run the following two executables on the same machine (each running in a separate sudo process), I see the Scan Response packets and data in the hcidump output

sudo hcitool -i hci0 lescan

sudo hcidump -i hci0 hci

example output from hcidump:

HCI Event: LE Meta Event (0x3e) plen 33

SCAN_RSP - Scan Response (4)

Thanks in advance for any ideas!
