We're seeing the following error randomly when ESP32 tries to connects to a particular WiFi router:
I (196641) wpa: PTK has been installed, it may be an attack, ignor it.
I (196645) wpa: GTK has been installed, it may be an attack, ignor it.
The connection then fails although the credentials are correct.
I see that there was a bug that produced a similar error that was fixed in esp-idf v2.1.1 -
https://github.com/espressif/esp-idf/issues/1273
However We're using esp-idf v3.1
The problem has only occurred using one particular router: Netgear R7000, using WPA2-PSK
I see that this message is generated within libwpa.a so it's not amenable to being debugged
I see a similar issue was reported after an OTA update and restart here:
https://github.com/espressif/esp-idf/issues/2320
There was no conclusion to this, if it is a question of some uninitialised memory being mis-interpreted as a handshake attack ie. possibly after a WDT reset, is there a way to clear the working memory of the wpa library?
Thanks in advance
Tim
