MSP432E401Y: http-server example, launchpad not available via hostname

Guenther Beulen

Part Number: MSP432E401Y

Tool/software:

Hello TI-forum!

I'd like to test the ethernet communication of the MSP432E401Y. So I took the launchpad, imported the example projet http-server from the simplelink installation folder and imported it in the code composer studio.

CCS: 12.3.0
Simplelink: 4.20.00.12
RTOS: TI/RTOS

I tested both, the ccs compiler and the gcc compiler. The behaviour was the same:
The launchpad got an IP-Address and I was able to open the http-page in a browser, if I enterd the address.
But I was not able to open the http site with the launchpads hostname "tisoc".

What could I do to reach the launchpad vie its hostname?

Hi,

Sorry, I'm confused. Which document says you can reach the LaunchPad using 'tisoc' as the host name? What is tisoc? If this is a domain name, where did you get it? The example is a http server with the IP address acquired from the DHCP sever on your network. First, I don't understand where you get 'tiosc' as the hostname? Second, in general, isn't this a DNS responsibility on the client side to translate a domain name (human readable name) into the IP address?

Hello,

thanks for your reply. This example uses dhcp, so I looked, if there was given a hostname to the MSP432E401Y. Searching with grep tells me, that tisoc was choosen:

$ grep -irn hostname ./
...
./httpserver_MSP_EXP432E401Y_tirtos_ccs/Debug/syscfg/ti_ndk_config.c:102:static char *hostname = "tisoc";
...

What can I do, to give the launchpad this or another hostname?

Hi,

Please refer to DHCP protocol on Wikipedia website and also the below post about the hostname. I don't know exactly how it is used by the DHCP server. You will need to consult with your router user's guide or your IT department about how and if the DHCP server on your company network does anything with the hostname provided by the client during the DHCP handshake. I don't think the hostname here is the same as the domain name where you would go through a DNS server to translate the human readable domain name into its corresponding IP address. IP address is what ultimately tells the IP (Internal Protocol) how to route the packets to its destination.
