I have a Node MCU V3 and I've been trying to rename the host name for my ESP8266, however even though I am using `WiFi.hostname("HostName")` I still can not see it change on my mobile phone when I search for new wifi connections.

Moreover it does not have any password, meaning I can connect to it without using any password.

I've come across with other topics as well but none worked for me so far.

Code: Select all#include <ESP8266WiFi.h>

const char* ssid = "ESP8266";
const char* password = "12345";

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  delay(10);
  Serial.println('\n');

  WiFi.hostname("ESP8266");
  WiFi.softAP(ssid, password);
 
  Serial.print("Access Point \"");
  Serial.print(ssid);
  Serial.println("\" started");

  Serial.print("IP address:\t");
  Serial.println(WiFi.softAPIP());
  Serial.println(WiFi.hostname()); // Here hostname is written as "ESP8266" but it shows up as "ESP-9414D5" on my phone
}

void loop() {
  // put your main code here, to run repeatedly:

}
