This code doesn't work without a timeout between the scan and the scan_results method on Windows:
import pywifi, logging
wifi = pywifi.PyWiFi()
wifi._logger.setLevel(logging.DEBUG)
interfaces = wifi.interfaces()
for interface in interfaces:
interface.scan()
print (interface.scan_results())
Result:
>>> import pywifi, logging

Would it be possible for scan to not finish before scan_results has the data available?
Another issue I noticed was that if I simply loop until scan_results doesn't return an empty list, the output I get is a list of just one or a subset of the Wi-Fi networks from the scan. If I call scan_results a second later (without calling scan again) it'll have the complete list of networks:
Code:
import pywifi, itertools, sys, time
from datetime import datetime
wifi = pywifi.PyWiFi()
interfaces = wifi.interfaces()
networks = []
timeout = 5
start_time = time.time()
for interface in interfaces:
interface.scan()
while time.time() < start_time + timeout and networks == []:
for interface in interfaces:
if interface.scan_results() == []:
print ("{}: nothing yet".format(datetime.now().isoformat(sep=' ', timespec='milliseconds')))
continue
else:
print ([x.ssid for x in interface.scan_results()])
for network in interface.scan_results():
networks += [(network.bssid, network.signal, network.ssid, network.key, network.id, network.cipher, network.freq, network.auth, network.akm)]
print ("Waiting half a second")
time.sleep(0.5)
print ([x.ssid for x in interface.scan_results()])
print ("Waiting 1 second")
time.sleep(1)
print ([x.ssid for x in interface.scan_results()])
break
It'd be nice if scan_results either returned an empty list or the complete list of networks instead of returning whatever it has at that point of time.
