Want to change ESP32 tcp port number in AP mode

Postby david@mandy » Tue Jun 12, 2018 9:25 am

Hello Admin,
I am using ESP 32 with esp-idf v3.0 (stable version). I am using TCP/IP in my application. In my code I have assigned the TCP IP and port number(80) and using browser I am trying to open one html page, and it is working fine. But when I change the port number in my code, the device is not able to push the html page. I tried with different port numbers but every time it is failing. It is only working with one port number i.e 80. I also tried with "TCP UDP test tool" app with different port numbers, but there it worked as expected. Only with the browser I am facing this problem.

What are you typing in the browser for port 88? Http://192.168.4.1:88 ?

Hello WiFive,

Thanks for your response.
When I am typing "http://192.168.4.1:80" in the browser it is working.
But when I change the port number in my code, the device is not able to push the html page.
Suppose if I set the port number 88 and in the browser I type "http://192.168.4.1:88" , at that time device is not able to push the html page.

Thanks.

What is the symptom of the failure? Is there any indication that the browser requests are being received by the ESP32 device?
