ESP8266-12F WiFi soft AP config.authmode failed - esp8266

Question

For a project I try do use the ESP8266 RTOS SDK.
First step I install the tools and the toolchain. The hello_world example and the other gpio example works fine. I try the softAP example and get a Guru Meditation Error: Core 0 panic'ed (StoreProhibited). Exception was unhandled Error. I figured out that the line 62 : .automode = WIFI_AUTH_WPA_WPA2_PSK not works. I tried WIFI_AUTH_WEP,WIFI_AUTH_WPA_PSK,WIFI_AUTH_WPA2_PSK but only with WIFI_AUTH_OPEN the softAP works. Anyone same behavior or some tips?

Answer 1

You have to run idf.py menuconfig and set the SSID and password values.

Answer 2

Password´s under 8 characters gets a Guru-Meditation ERR if the
wifi_config.ap.authmode = WIFI_AUTH_WEP or,
wifi_config.ap.authmode = WIFI_AUTH_WPA_PSK or,
wifi_config.ap.authmode = WIFI_AUTH_WPA2_PSK . Other authmodes not yet testet.
To provid this Error, make sure your pw has more then 7 characters or/and set
the If-Condition after the wifi_config to:
if (strlen(EXAMPLE_ESP_WIFI_PASS) < 8) {
wifi_config.ap.authmode = WIFI_AUTH_OPEN;
ESP_LOGI(TAG," pw-lenght under 8 charcters. Set WIFI_AUTH_OPEN");
}
Your WiFi is not protectet but your µC not crashes.
