Hi, i have the same problem. Have you found a solution ?

Nope.

This is because the output of the command of "'iwpriv wlan0 p2p_get status" in file wfd.py is not being parsed correctly in the script (There is a missing space)

Output is of the form "Status = 1".

To fix the issue, change line 56 to the following:
match = re.search(r'Status =(\d*)', output)

from file wfd.py:

def p2p_status_get():
#print 'p2p_status_get:'
output = get_stdout('iwpriv wlan0 p2p_get status')
match = re.search(r'Status=(\d*)', output)
return int(match.group(1)
