ESP8266-12F WiFi 软 AP config.authmode 失败

如何解决ESP8266-12F WiFi 软 AP config.authmode 失败

对于一个项目，我尝试使用 ESP8266 RTOS SDK。第一步我安装工具和工具链。 hello_world 示例和另一个 gpio 示例工作正常。我尝试了 softAP 示例并收到 Guru Meditation Error: Core 0 panic'ed (StoreProhibited). Exception was unhandled 错误。我发现 line 62 : .automode = WIFI_AUTH_WPA_WPA2_PSK 不起作用。我试过 WIFI_AUTH_WEP,WIFI_AUTH_WPA_PSK,WIFI_AUTH_WPA2_PSK 但只有 WIFI_AUTH_OPEN 才能使用 softAP。有人有相同的行为或一些提示吗？

解决方法

您必须运行 idf.py menuconfig 并设置 SSID 和密码值。

如果密码少于 8 个字符，则会出现 Guru-Meditation ERR wifi_config.ap.authmode = WIFI_AUTH_WEP 或， wifi_config.ap.authmode = WIFI_AUTH_WPA_PSK 或， wifi_config.ap.authmode = WIFI_AUTH_WPA2_PSK 。其他身份验证模式尚未测试。

要提供此错误，请确保您的密码超过 7 个字符或/并设置 wifi_config 后的 If-Condition 为：

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"); 
}

您的 WiFi 没有受到保护，但您的 µC 没有崩溃。
