Basic sketch to comunicate with esp in AP mode with phone
Posted: Wed Feb 27, 2019 12:51 pmHi,
I just started with programing, arduino and stuff. I watched and read a lot of tutorials and examples of comunicateing esp8266 with multiple devices, but I think I'm missing some important thing, so my project doesn't work. :/
I want to use TCP connection to send message to esp by phone app.
I think that in void loop() should be something like if(XXX.available()){readStringUntil('\r');} but usually I got error "available is not member of ESP8266WiFi library"(something like that). In tutorials XXX part is usually called a server or client and define in multiple ways. :/
My code:

#define APSSID "ARDUINO UNO"
#define APPSK "12345678"
const char *ssid = APSSID;
const char *password = APPSK;
IPAddress local_IP(192,168,0,1);
IPAddress gateway(192,168,1,1);
IPAddress subnet(255,255,255,0);
WiFiServer server(80);
void setup()
{delay(500);
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, HIGH);
Serial.begin(115200);
Serial.println();
WiFi.softAP(ssid,password);
WiFi.begin();
WiFi.softAPConfig(local_IP, gateway, subnet);
IPAddress myIP = WiFi.softAPIP();
Serial.print("AP IP address: ");
Serial.println(myIP);
Serial.println("");
Serial.print("Connected to ");
Serial.println(ssid);
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
Serial.println(WiFi.softAPIP());
server.begin();
}
void loop() {
WiFiClient client = server.available();
if (client) {
digitalWrite(LED_BUILTIN, LOW);
String req = client.readStringUntil('\r');
Serial.println(req);
client.flush();
}
if(!client){
digitalWrite(LED_BUILTIN, HIGH);
}
/*else{
Serial.println("no data");
delay(1500);
}
*/
