Documentation URL

https://docs.micropython.org/en/latest/library/network.WLAN.html

Description

The documentation report the following

There are five values for security:

0 – open
1 – WEP
2 – WPA-PSK
3 – WPA2-PSK
4 – WPA/WPA2-PSK

and two for hidden:

0 – visible
1 – hidden

While using the WLAN.scan() function, I got the following results:

Most of the networks in my neighbourhood are reporting

security = 5

and hidden:

1 - Most of them, and by the way, the networks are visible (so, they should be 0)
2 - seems hidden
5 - visible (homekit device)
7 - One of my home Wi-Fi (made by an old D-Link router)
9 - My main home Wi-Fi (made by a TP-Link router)

Any thoughts ?

ESP32 WLAN.scan() returns incorrect hidden flag

bug

Hi, new comer to micropython on ESP boards here. Just start to use this and realized the hidden flag in WLAN.scan() result is incorrect.

  • The documentation mentioned this flag as (ssid, bssid, channel, RSSI, authmode, hidden) , 0 - visible, 1 - hidden; but it's a bool not int.
  • In my test, all APs in results are always with hidden = False, though apparently the SSID returned is b'' and in wavmon these are reported as <Hidden SSID> (I mean confirmed as hidden not AP with empty SSID)

uos.uname() = (sysname='esp32', nodename='esp32', release='1.19.1', version='v1.19.1 on 2022-06-18', machine='ESP32 module with ESP32')
