Is there any way to change the default name (ESP_xxxxx) that the module generates?

Which firmware are you using?gre_gor– gre_gor2016-10-07 11:57:49 +00:00Commented Oct 7, 2016 at 11:57

Hi gre_gor! I'm not using any firmware, I am using the Arduino IDE.Sr Julien– Sr Julien2016-10-09 04:28:34 +00:00Commented Oct 9, 2016 at 4:28

@SrJulien You must be using a firmware on the ESP or it wouldn't work, please determine it before we can really help you efficiently.Avamander– Avamander2017-12-12 16:54:39 +00:00Commented Dec 12, 2017 at 16:54

The function is: WiFi.hostname("Name");, make sure you call it before Wifi.begin()

This is the actual (modern) answerAndrew Bullock– Andrew Bullock2020-02-26 20:04:22 +00:00Commented Feb 26, 2020 at 20:04
This line of code should hopefully do a difference.
wifi_station_set_hostname(myHostname);

Hi canadiancyborg! I tried to use 'wifi_station_set_hostname', but without success! I appreciate any suggestions!Sr Julien– Sr Julien2016-10-09 04:33:38 +00:00Commented Oct 9, 2016 at 4:33
Here you are the code where you can see how you can change network name of your ESP8266 working in AP mode:
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
IPAddress ip(192,168,1,81); // choose IP address
IPAddress subnet(255,255,255,0);
ESP8266WebServer server(80);
void handleRoot() {
String page = "<!DOCTYPE html>\n";
page += "<html>\n<body>\n<h1>Some heading</h1><br>Generated by ESP8266\n</body>\n</html>";
server.send(200, "text/html", page);
}
// what to do when accessed through http://ip_address/something_undefined
void handleNotFound(){
String message = "File not found\n\n";
message += "URI: ";
message += server.uri();
message += "\nMethod: ";
message += (server.method() == HTTP_GET)?"GET":"POST";
message += "\nArguments: ";
message += server.args();
message += "\n";
for (uint8_t i=0; i<server.args(); i++){
message += " " + server.argName(i) + ": " + server.arg(i) + "\n";
}
server.send(404, "text/plain", message);
}
void setup(void){
Serial.begin(74880); // so you can see debug messages automatically sent by ESP8266
WiFi.mode(WIFI_AP);
WiFi.softAPConfig(ip, ip, subnet); // declared as: bool softAPConfig (IPAddress local_ip, IPAddress gateway, IPAddress subnet)
WiFi.softAP("SOME_NAME", "password", 7); // network name, network password, wifi channel
IPAddress myIP = WiFi.softAPIP();
Serial.println();
Serial.print("AP IP address: ");
Serial.println(myIP);
server.on("/", handleRoot); // what to do when accessed through browser using http://IP_address
// what to do when accessed through http://ip_address/test
server.on("/test", [](){
server.send(200, "text/plain", "This is another page");
});
server.onNotFound(handleNotFound);
server.begin();
Serial.println("HTTP server started...");
}
void loop(void){
server.handleClient();
}
