LAUNCHXL-CC3235SF: WIFI-HTTP code does not work in STA mode

Hello; My problem is actually this. You know the ready-made WIFI-HTTP code, right? In this code, mysimplelink.net is connected to the address and many operations can be done.
The problem is that the code works very successfully in AP mode. but when I put the code in STA mode, I cannot connect when I type mysimplelink.net address in the browser. I can connect when I type the ip address that the device receives. What is the cause of this problem and what is the solution I am actually looking for this 

Code:

There is NO solution at CC32xx side. Only way is change DNS record inside your DNS server.

What do you mean by this? You mean change my DNS address. For example, if my cc3235sf device has an ip address of 192.168.10.145, what should the DNS be. are you talking about something like this?

First of all, thank you for your answers.
However, I am interested in what the solution is rather than what my problem is.
I need to solve these problems. I need to use this wifi-http structure. How can I use this structure by solving this problem. what is the solution?
I can send you the codes with the codes related to the codes.
Please let's find a solution to my problem.

When I type mysimplelink.net/example.html in AP mode, the html page opens and works properly. I can't do the same in sta mode. When I type 192.168.10.145/example.html in STA mode, the html page opens. I don't understand where I'm going wrong. actually the code shows that it works in sta mode. the only problem is that I want to access the html page in this way mysimplelink.net/example.html without entering the ip address

Hi,

Asking same question multiple times will not solve your issue. Only thing you can try is to use mDNS. But you will find that this way is far from ideal.

Maybe you should read some course of TCP/IP network and DNS (my recommendation is book Tcp/Ip from Heather Osterloh). Than you will realise, why your question have no easy solution.

Jan

I can't switch to TCP/IP protocol. I cannot implement this solution right now. I need to solve this with the current terms and conditions. thanks for your suggestion.
Sometimes it's hard to understand why TI officials don't take care of the problems.
So I thank you for that.

Hi,

HTTP is just protocol above TCP/IP. That mean with HTTP you are using TCP/IP.

• As I said solution is at network infrastructure side not a CC32xx side.
• Only thing what you can try at CC32xx is to use mDNS for resolving address like mysimplelink.local. But this will not work at all cases.
• It may to exist other approach when you send IP address to some your Cloud server and show IP address at that server according your external IP, but this is not great as well.
• You can create own client application for finding your device at network and opening web-browser with such IP. Many manufacturers of network devices use this way.
• Or you can public your own RFC standard, wait for approved and implemented into wide range operating systems and web browser. This can take 8-10 years.

TI care about problems o their customer. But you are asking for solution of thing which does not have solution at present time. Not only for TI but for other manufacturers.

Please answer me for this question. You buy IP camera and you connect it into network. IP camera use DHCP. You want to open webpages of this camera. How you can do this? How do you determine IP address of IP camera?

Greetings;
First of all, there is no rule that everyone will have your experience or knowledge. Therefore, here is someone who has just started working with TI. And you are giving solution suggestions as if the person in front of you has mastered everything.
I don't want something that doesn't exist. I don't believe that there is no solution to this situation. Because when you type the ip address that the device receives into the web browser, the system works. However, when you try to connect with the domain name, the system does not work, I do not think there is no solution to this.
You are giving me very broad suggestions. However, I am not someone who knows everything here. If I was someone who knew everything, I would not ask questions anyway.
Therefore, I expect you to answer more specifically and through code or specific examples. You are not obliged to do this, of course.

Hi,

I think if you want develop network (WiFi) device is mandatory to have at least basic knowledge how computer networks works.

As I said. You can try mDNS, maybe it will work at your case. Or you can create native application (for Windows, Android, iOS) which will find your device at network and open device webpages as use many network devices manufacturers. Or if your device have LCD display show IP address at LCD or show QR code with IP address. But as I said many times there is no standard and universal solution when device is connected into network based on DNS. If you don't believe me, just find few manuals of different network devices and do your own research.

Jan

What I don't understand is why there is a DNS problem in STA mode when the device works properly in AP mode.  

Hi,

At AP mode is DNS served by DNS server at CC32xx. But at STA mode is used DNS server at your network. And your DNS server does not have idea about your CC32xx device. Some DHCP servers can configure DNS server at your network by hostname reported from CC32xx (field URN at CC32xx settings) when DHCP is used. But this depends on your network infrastructure.
