Programming problem with WiFiscan.py

Official Hardware Nano Family Nano RP2040 Connect

I am having problems with the wifi-scan.py example found on this page:

The output of wlan.scan() appears to be different from the way it is parsed in the code that follows.
I need help parsing the new output of wlan.scan().

# Scan Example

# This example shows how to scan for Wi-Fi networks.

import time, network

wlan = network.WLAN(network.STA_IF)
wlan.active(True)

print("Scanning...")
while (True):
   scan_result = wlan.scan()
   for ap in scan_result:
       
       print (ap)
       print()
       #print("Channel:%s RSSI:%s Auth:%s BSSID:%s SSID:%s"%(ap))
       print("SSID:%s %s Channel:%d RSSI:%d Auth:%d BSSID:%d "%(ap))
        
   print()
   time.sleep_ms(2000)

Here is the output:

Scanning...
(b'TELUS1837', b'\xfc+\xb2\xe18B', 11, -56, 4, 1)

SSID:b'TELUS1837' b'\xfc+\xb2\xe18B' Channel:11 RSSI:-56 Auth:4 BSSID:1

  for ap in scan_result:
    print(ap)
    print()
    #print("Channel:%s RSSI:%s Auth:%s BSSID:%s SSID:%s"%(ap))
    # Add parentheses and commas around ap
    print("SSID:%s %s Channel:%d RSSI:%d Auth:%d BSSID:%d "%(ap[0], ap[1], ap[2], ap[3], ap[4], ap[5]))
    print()
  time.sleep_ms(2000)

Maybe this helps.

Thanks. I'll give it a try and post the results.

Here is the result of your code:

Scanning...
(b'TELUS1837', b'\xfc+\xb2\xe18B', 11, -54, 4, 1)

SSID:b'TELUS1837' b'\xfc+\xb2\xe18B' Channel:11 RSSI:-54 Auth:4 BSSID:1

Everything is correct.

The output shows one access point that was detected by the scan. The SSID is TELUS1837, which is the name of the network. The BSSID is fc:2b:b2:e1:38:42, which is the MAC address of the router. The channel is 11, which is the frequency band used by the network. The RSSI is -54, which is the signal strength in decibels. The Auth is 4, which is the authentication mode used by the network. The last number 1 is not part of the output, but a reference to the first result in the scan list.

I don't want to force you, but it's best to mark the solution as "solution" so that it shows that the problem has been solved!
