Hostname (standard PC-192-168-xxx-xxx)

This is what we were afraid of. So the next question would be: Considering the market share of Windows based operating systems, do you plan to implement the protocol so that Windows users can access devices based on your hardware in a customer-friendly way, too?

Hi,

We attach great importance to your suggestion.

It will be supported in next SDK.

Thanks for your interest in Espressif Systems and ESP8266 !

[blubb]

Thanks. We're already looking forward to it!

Hi, is the feature implemented in the new SDK 1.3.0? I could not find it in the change log.

[ESP_Faye]

Hi,

Yes, have a try with the latest sdk_v1.3.0

If your problem is still unsolved, please feel free to let us know.

Hmmm, no, the Windows 10 machine I'm currently sitting on cannot access the module by host name. Is there something I need to pay attention to? I'm setting the host name using wifi_station_set_hostname before wifi_station_dhcpc_start.

What command are you issuing at the windows side to try and reach the ESP device by hostname? What is the full hostname address you are trying?

Hi,

So sorry for the inconvenience. I checked it with our engineer again, esp_iot_sdk_v1.3.0 did not add this optimization.

Here is a patch based on esp_iot_sdk_v1.3.0 to support this new feature.

Please replace it in folder "lib" and add definition below in espconn.h

Code: Select all

void espconn_nbns_init(void)

Call it after ESP8266 station connected to AP and got a IP address. For example,

Code: Select all

wifi_station_set_hostname("esp8266");
espconn_nbns_init();

Hi Faye, thank you very much! I just tried it and, well, it *almost* works:

When I ping the ESP by host name, Windows tries to ping IP 168.0.135.0 which is not correct. The correct IP would be 192.168.0.135 in my case.
Looking at the IPs I think it was shifted by 1 byte accidentally! So this should be easy to fix if you look at your code.

Could you also be a little more specific on when to call espconn_nbns_init() in our finished application?

- Do I need to call it every time ESP8266 got an IP?
- Do I need to call it every time I change the host name with wifi_station_set_hostname?
- Or is it enough calling it only once (in user_init() maybe)?
