Oh ! that seems even simpler since you don't need to verify remoteIP() against subnets ...

You can also set a flag variable at wifi setup stage. Simpler and faster as no addition method call to detect ip configuration. Like this:

Code: Select all

boolean WifiConnected = true;  // <- global variable
void setupWifi() {
  WiFi.mode(WIFI_STA);

  // starting wifi
  String esid ="ssid";
  String epass = "pass";

  if ( esid.length() > 2 ) {
    if ( epass.length() > 2 ) {
      WiFi.begin(esid.c_str(), epass.c_str());
    } else {
      WiFi.begin(esid.c_str());
    }
    if (WiFiAvailable()) {
      return;
    }
  }

  WiFi.disconnect();
  WifiConnected = false;  // <- this point
  WiFi.mode(WIFI_AP);
  WiFi.softAP("Web Remote Receiver");
}

In fact, webserver.hostHeader() and webserver.client().localIP() is returning the same thing, so in both cases you need to verify if it is part of STA or AP subnets.

the proper way to check if a given client belongs to particular side of the network in pseudo C code:

Code: Select all

if(((uint32_t)client.ip & (uint32_t)ap.mask) == ((uint32_t)ap.ip & (uint32_t)ap.mask)){
  //this client is AP client
} else {
  //this client is on the STA side
}

the Host header is actually the name of the address that you typed to get to the page. It can be IP or DNS name. It is used in virtual hosting to decide which virtual server is this request for (when you host more than one site on the same server)
