What to do in case of wifi disconnection / reconnection

[xgnata]

Hi,

I have a code to check periodically if we are connected on wifi and to try to reconnect in case of disconnection:
if (WiFi.status() != WL_CONNECTED) { SerialAndTelnetPrintln("Trying to (re)connect to WiFi."); WiFi.setHostname(Hostname.data()); // https://github.com/espressif/arduino-esp32/issues/6700 WiFi.mode(WIFI_MODE_NULL); WiFi.mode(WIFI_MODE_STA); wifiMulti.run(Clock.Params.WiFiConnectTimeout * 1000); }

Once WiFi.status() == WL_CONNECTED, I start a server with
Clock.ws.onEvent(onAsyncEvent); Clock.server->addHandler(&Clock.ws); Clock.server->on("/", HTTP_GET, [](AsyncWebServerRequest *request) { SerialAndTelnetPrintln("HTTP_GET request."); request->send(LittleFS, "/index.html", "text/html", false, TemplateProcessorCallback); }); Clock.server->on("/", HTTP_POST, [](AsyncWebServerRequest *request) { HTTP_POST_request_handler(request); }); // Start server Clock.server->begin();

The question is : Should I call again server->begin(); after a wifi disconnection/reconnection? Should I re-run the full server configuration sequence I've posted above?
Anyway...is it a decent way to handle disconnection/automatic reconnection?

Hi,
No need to do anything.
Whether you are using eth or wifi, a disconnect followed by a reconnect won’t have any impact on ESPAsyncWS : it will continue working and accepting requests when network comes back.

Wow, what a swift answer! Thanks!
