4WAY_HANDSHAKE_TIMEOUT

[slowsquirrel69]

When I load a sketch that does a network scan I see my network

========================
WiFi scan start
[D][WiFiGeneric.cpp:337] _eventCallback(): Event: 1 - SCAN_DONE
WiFi Scan done
29 networks found
1: ARLO_VMB_1792897479 (-51)*
2: CAKE-2G (-53)*

When I load a sketch to connect to my network I get

=======================
Attempting to connect to WPA SSID: CAKE-2G
[D][WiFiGeneric.cpp:337] _eventCallback(): Event: 0 - WIFI_READY
[D][WiFiGeneric.cpp:337] _eventCallback(): Event: 2 - STA_START
[D][WiFiGeneric.cpp:337] _eventCallback(): Event: 5 - STA_DISCONNECTED
[W][WiFiGeneric.cpp:353] _eventCallback(): Reason: 15 - 4WAY_HANDSHAKE_TIMEOUT

All other network devices can connect iPhone, Android, laptops, etc..

Why can't the Adafruit HUZZAH32 – ESP32 Feather Board connect?

@slowsquirrel69 I have the exact same problem with the HUZZAH32, but my code worked before. I guess the problem occurs because I updated to the latest platform version. Did you find a solution for the problem?

[TheNetStriker]

@slowsquirrel69 I found out that my code works again if I use the platform version 1.9.0:

platform = espressif32@1.9.0

[HamzaHajeir]

+1 same @ Version 1.0.4 , DevkitV1

[cagney]

try 1.0.2, see #3225

Please try this to connect:

WiFi.mode(WIFI_STA);
WiFi.begin("...", "...");
WiFi.persistent(false);
WiFi.setAutoConnect(false);
WiFi.setAutoReconnect(true);
WiFi.setTxPower(WIFI_POWER_2dBm);

The important part is the setTxPower at the end.
