At my current app code level though, it is failing every time. The correct place to set the host is after start and before connect, so I believe the call is in the right place. Since the IDF Default-Event-Loop does the event dispatch, the notion of doing a busy-delay in a handler is not a good idea as a solution.

I was able to trim my app down to only the wifi handling and interestingly the host name setting is working At this point the major difference after a number of trim down exercises is running the webserver.

Espressif ESP Available now!Pages: [1]. Ethernet shield hostname. Hello, my Arduino Ethernet Rev. The trouble I encounter is, I can only view the website if the IP address is known. I have had a view through various forum sites but unlikely i haven't been able to find a solution. Currently i do the following in the header: Code: [Select].

Re: Ethernet shield hostname. Maybe I don't understand your problem but from what I got, I'd suggest to use fixed IP numbers and just enter them into your hosts file yes, even Windows has one. I don't know what "Angry IP Scan" does you didn't provide a link to itso my guess is, that it uses some Windows-only stuff to show a name and that will not work with the Arduino. Hi pylon, thank you for your answer you are absolutely correct a fixed IP would work but i wouldn't like to have to gather for each site where i want to install my arduino a IP Address and then configure it.

This is why i need it to be working with DHCP. Which i also dont want Angry IP Scan will scan a range of the network and return if the Computer respond to the ping and returns the hostname In the attached picture it should show Project as a host but it gives the hostname of our old printer that used to have this IP assigned. If i use the old hostname of the printer in the address bar of the browser it directs me to my arduino but that is not state of the art.

I would want my clients to be able to look at the back of the housing and type the name into the address line of the browser and be connected to the website.

Hello pylon, thanks for the link, I will try that and update you if it has been a success. Quote from: spylive on Jun 16,pm. Quote from: SurferTim on Jun 16,pm. Quote from: Osqui on Aug 04,am.

I think my Wifi network did not support DNS. I will try out on my Ethernet network and will let you know. Thanks, Naeem.

If you search for that keyword in the docs you will find the usage instructions.

The one possible wild guess I have is that the access point "remembers" the first name for a given MAC address that it finds. Looking there, I seem to see a list of all the previous devices that have ever connected including their MAC addresses and "Device Name".

ESP32 Arduino: Getting station interface hostname

It is in the realms of possibility that if we rebooted our access points and THEN tried a connection with a new host name, then it might work. Another puzzle to me is the purpose of this interface host name.

This thread begins with the title of "changing dnsName" I'm not sure what effect "supplying" a name here actually has. Dynamic lookup of names might be performed through mDNS. I don't believe that if we were to say "ping espressif" it would resolve. I don't think access points run DNS servers. So that would be quite fast. Best, Malte.

About Us Espressif Systems is a fabless semiconductor company providing cutting-edge low power WiFi SoCs and wireless solutions for wireless communications and Internet of Things applications. Espressif ESP Available now!To test this functionality, we will first connect the ESP32 to a WiFi network and then obtain the hostname. The hostname should be correctly resolved to the ESP32 IP and thus the machine should be able to ping the it and receive an answer.

We will start the code by including the WiFi. Naturally, we will also need the WiFi network credentials, more precisely the network name and password. Moving on to the Arduino setup, we will initialize the serial interface, so we can output the hostname we will obtain.

Then we will call the begin method on the WiFi extern variable, to start the connection to the WiFi network. This method receives as first input the network name and as second input its password.

We can obtain the status of the connection by calling the status method on the WiFi variable. Finally, to obtain the hostname, we simply need to call the getHostname method of the WiFi variable. This method takes no arguments and returns as output the hostname as a string.

You can check the implementation of this method here. To test the code, start by compiling it and uploading it to your device using the Arduino IDE. After that, you should get an output like the one on figure 1, which shows the hostname getting printed to the console.

Above, we also have the local IP assigned to the device on the network. To do it, open a command line on a machine connected to the same network and send the following command:. As shown in figure 2, the hostname used in the command should be resolved to the actual IP of the ESP32 on the network note that it matches the IP obtained on figured 1. Thus, the ESP32 should successfully answer the ping request. Figure 2 — Pinging the ESP32 using its hostname. Even though it seems to be possible to set it on the ESP32 side the next calls to the getHostname will return the new oneI cannot seem to, for example, ping the ESP32 on the new hostname.

To do it, open a command line on a machine connected to the same network and send the following command: ping espressif As shown in figure 2, the hostname used in the command should be resolved to the actual IP of the ESP32 on the network note that it matches the IP obtained on figured 1.

Introduction In this tutorial we will learn how to obtain the hostname of the ESP32, using the Arduino core.

To test this functionality, we will first connect the ESP32 to a WiFi network and then obtain the hostname. After that, we will ping the ESP32 from another machine connected to the same network using the obtained hostname as already covered here, the ESP32 natively answers to ping requests when connected to a network.

The hostname should be correctly resolved to the ESP32 IP and thus the machine should be able to ping the it and receive an answer.
