Wifi authmode irregularities

[bill88t]

CircuitPython version

Latest master, current commit e39fbf1b26b4fd3b66313e51ccc3db0eba7bd58a
Discovered on s3 while testing idf5, also exhibited on regular esp32.

Code/REPL

import wifi
a = wifi.radio.start_scanning_networks()
for i in a:
    print(i.ssid)
    print(i.authmode)
a = wifi.radio.stop_scanning_networks()

Behavior

Something is wrong with authmodes, and it's consistent.

Description

This also prevents connections to those networks that are reported incorrectly.
Sometimes the networks are reported to not be found, and sometimes unknown failure 15.

Additional information

No response

Is the 8.2.6 output correct?

[bill88t]

Is the 8.2.6 output correct?

From a small amount of testing yes. I did not test 8.x in many places.
The number and authmodes of nearby networks affects it.

This is an upstream bug, I filed a bug.
espressif/esp-idf#12517

[bill88t]

This bug has been confirmed in:

• CiruitPython
• Arduino beta esp plugin 3.0.0-alpha2
• ESP-IDF wifi example scan

On all esp32 chip variants.
If we are to ship idf5, we need to disable all authmode checks. esp does no authmode checks in circuitpython code huh? Then idf is maybe at fault again?

[bill88t]

This issue has been fixed upstream with espressif/esp-idf@615d928.
Did confirm with C6 and idf/examples.

Once we upgrade esp-idf in CP, this will be fixed.
Do note however, some more authmode changes have been made since last update.

[bill88t]

This has been fixed. Closing.
