Compile issue: error: 'union arduino_event_info_t' has no member named 'disconnected'

[flyboy013]

I’m getting errors when attempting to compile ESP32RET. Specifically, I’m getting:

wifi_manager.cpp:36:32: error: 'union arduino_event_info_t' has no member named 'disconnected'; did you mean 'eth_connected'?

This error is in WiFiManger::setup(), which is where info is defined as type WiFiEventInfo_t. Here is an excerpt of the code:

  WiFiEventId_t eventID = WiFi.onEvent([](WiFiEvent_t event, WiFiEventInfo_t info) 
        {
           if (SysSettings.fancyLED)
           {
               leds[0] = CRGB::Red;
               FastLED.show();
           }
           Serial.print("WiFi lost connection. Reason: ");
           Serial.println(info.disconnected.reason);
           SysSettings.isWifiConnected = false;

ESP32RET includes WiFi.h which includes WiFiType.h which defines arduino_event_info_t as WiFiEventInfo_t.

WiFiEventInfo_t is defined in WiFiGeneric.h as show below. There is no member disconnected.

typedef union {
        wifi_event_sta_scan_done_t wifi_scan_done;
        wifi_event_sta_authmode_change_t wifi_sta_authmode_change;
        wifi_event_sta_connected_t wifi_sta_connected;
        wifi_event_sta_disconnected_t wifi_sta_disconnected;
        wifi_event_sta_wps_er_pin_t wps_er_pin;
        wifi_event_sta_wps_fail_reason_t wps_fail_reason;
        wifi_event_ap_probe_req_rx_t wifi_ap_probereqrecved;
        wifi_event_ap_staconnected_t wifi_ap_staconnected;

        wifi_event_ftm_report_t wifi_ftm_report;

        smartconfig_event_got_ssid_pswd_t sc_got_ssid_pswd;
        esp_eth_handle_t eth_connected;
        wifi_sta_config_t prov_cred_recv;
        wifi_prov_sta_fail_reason_t prov_fail_reason;
} arduino_event_info_t;

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

What am I missing? Has arduino_event_info_t changed such that member disconnected was removed?

Thx.

Yes, recently they changed the names of some of the wifi status fields and I didn't update the code to match. So, if you (as I assume) are using the newest arduino-esp32 then compilation breaks like you saw. I just pushed a commit to fix this. Or, just comment out that whole block. It isn't strictly necessary to have that block but it does try to fix wifi connection problems.

I am using -> info.wifi_sta_disconnected.reason instead of the deprecated info.disconnected.reason and ARDUINO_EVENT_WIFI_STA_CONNECTED, ARDUINO_EVENT_WIFI_STA_GOT_IP, ARDUINO_EVENT_WIFI_STA_DISCONNECTED instead of SYSTEM_EVENT because thats not defined properly.

@collin80 Thank you.
