Rebooting...

I change the order of Statement ,than it is worked.

  WiFi.begin(ssid, password);
  WiFi.setHostname("node1");

I tried it both way on a DFrobot firebeetle esp32 board and it DOES not work for me.
when I ping -a IP_ADDRESS I get "espressif.lan." as node name.

Here is the test:

#include <WiFi.h>

void setup() {
// put your setup code here, to run once:

}

void loop() {
// put your main code here, to run repeatedly:
Serial.begin(115200);
WiFi.mode(WIFI_STA);
WiFi.setHostname("My ESP32 Test Node");
WiFi.begin("MyAccessPoint", "MyPass"); //put real data here.
WiFi.setHostname("ESP TEST NODE");
while (WiFi.waitForConnectResult() != WL_CONNECTED)
{ Serial.println("Connection Failed! Rebooting...");
delay(5000);
ESP.restart();
}
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
delay(5000);
ESP.restart();
}

hostname != dns . Your dhcp server is doing whatever you are seeing there in dns.

My google mesh router is providing the same name no matter what I do...:("espressif.lan.")
I have multiple ESP boards and I would like to give each a uniqe name of my choosing.
How do I change it to my specifications ?

[vcmorini]

@doronby , any luck?

[HarmOtten]

I have the same issue.
When I don't set the hostname in the sketch, the DHCP server sees it as "espressive".
When I do WiFi.setHostname("abcd"); as first statement in my sketch, the hostname in the DHCP server shows empty.
Board: ESP32 DevKIT V1
IDE name: Arduino IDE v1.8.9

All my ESP8266 boards are able to set a hostname. Why isn't this possible with ESP32?

[minida28]

Should I open a new ticket for this...?
In AP mode, I changed the hostname using WiFi.softAPsetHostname("myname").
When I checked the hostname using WiFi.softAPgetHostname(), the result hostname is always espressif.

[HarmOtten]

I was hoping this issue could be re-opened...

[tom-oleson]

I hope this issue can be re-opened. It is NOT fixed for the ESP32 library. I've tried every combo I've seen discussed and none of them work. Always shows up blank on my WiFi router. Every other WiFi device I connect with shows up perfectly but not my ESP32.

Neither, WiFi.setHostname() nor WiFi.softAPsetHostname() work in any call location.

Arduino IDE 1.8.10
ESP32 Dev Module 1.0.4 (and tried 1.0.3)

Hi !
Same here. No Hostname shows up in my router.
Using also 1.8.10 with 1.0.4 Lib.
