Error when compiling code NODE MCU ESP8266-12E module in Arduino ide

Question

Here is my sketch:

#include<ESP8266WiFi.h>
char* ssid = "xxxxxxxx";
char* pass = "xxxxxxx";
void setup() {
 WiFi.begin(ssid,pass);
 Serial.begin(9600);
 while(WiFi.status()!=WL_CONNECTED)
 {
 Serial.print(".");
 delay(500);
 }
 Serial.println("");
 Serial.print("IP Address: ");
 Serial.print(WiFi.localIP());
}

Here is the error:

exist or your board is not connected

• dandavis: does the code "verify"?
• Sim Son: This looks more like an error while uploading than on compilation to me. Have you selected the correct board settings?

Answer 1

The section

void loop() {
}

Is missing in the code, add it and recompile and.....
