Bluetooth Error (9, 'Bad file descriptor')

[anthonysutera]

Hi,

I receive the following error when I run it:

ble thread started
Traceback (most recent call last):
File "testblescan.py", line 18, in
blescan.hci_le_set_scan_parameters(sock)
File "/home/pi/blocktrain/test/iBeacon-Scanner-/blescan.py", line 107, in hci_le_set_scan_parameters
old_filter = sock.getsockopt( bluez.SOL_HCI, bluez.HCI_FILTER, 14)
_bluetooth.error: (9, 'Bad file descriptor')

Any kind of helps will be appreciated!

Thank you.
