Show WIFI-Setup (enable AP-Mode)

This example shows how to set up the mode of the WIFI module by the CWMODE command. This example sets the module to CWMODE=3 which enables station and accesspoint mode.

void setup() {
  // put your setup code here, to run once:
  pinMode(2, OUTPUT);
  pinMode(13, OUTPUT);

  Serial.begin(115200); //Opens serial connection to WIFI module
  SerialUSB.begin(115200); //Opens USB-Serial connection for terminal

 //Preparing Wifi-module
 digitalWrite(WIFI_EN_PIN, LOW); //turns WIFI module off
 digitalWrite(13, HIGH); //set module to normal mode
 delay(100);              // wait a short time
 digitalWrite(WIFI_EN_PIN, HIGH); //turns WIFI module on

    //wait until the module is ready
    while (!Serial.find("ready\r\n")) {}
    SerialUSB.write("Module is ready\r\n");

    //Set module to Station&AP mode to enable WIFI Setup
    while (!Serial.find("OK\r\n")) {}
    SerialUSB.println("Module changing to AP&Station mode");
