How can I use HTTP with the WiFi Driver (CC3000) ?

Bernard Brault

I am working on a new project with the Tiva Launchpad and the CC3000 Booster Pack using CCSv5 and RTOS.

I want the UI for my application to be browser based. So I need to use the RTOS HTTP application module.

The CC3000 has a built-in TCP-IP stack but it does not have HTTP built-in. The RTOS WiFi driver provides an API to access the CC3000 built-in TCP-IP stack. The RTOS HTTP module is designed to operate over the RTOS TCP/IP stack as opposed to the built-in TCP-IP stack of the CC3000.

Folks in the CC3000 forum confirmed that I cannot use the RTOS TCP-IP stack with the CC3000 but I have to use its built-in stack. Hence my question:

How can I use the RTOS HTTP module over the RTOS WiFi driver? Thanks for your responses.

The Simple HTTP Server example from TI should be a good start for you: http://processors.wiki.ti.com/index.php/CC3000_Wi-Fi_Downloads#Basic_Wifi_Application_and_Sample_Demos You just need to port it to Tiva.

Hi Maciej

I have seen this example. It does not make use of RTOS at all.

I am trying to understand how to use RTOS HTTP directly with RTOS WiFi.

Bernard,

we have an internal wiki page on how to use the CC3000 as a HTTP web server. I can't say for sure when it's ready; but we will make it available externally.

Added after posting it:

The wiki example uses TI-RTOS instead of a "bare-metal" application.

This is exactly what I am looking for.

Any chance you could find out when it will be released? How can I check for this on TI website. Notification?

Thank you

I've submitted a bug ID for this, but I don't know how to make this public. In any case, its on our radar.

Hi Tom,

Any updates on when the example document you mentioned will be made public?

I'm also working on a project that ideally should run a HTTP server via the CC3000 on a TIVA MCU using TI RTOS.

Thank you.

I with Marius, this example would be great to see!

Marius, if they don't have anything yet, I suggest starting with the TI-RTOS CC3000 TCP Echo example and porting some code from this example - http://processors.wiki.ti.com/index.php/CC3000_HTTP_Web_Server_Application_for_MSP430F5529. I know its a lot of work, but at least it's a start.

Glenn.

Hi Glen,

Thanks.

I have actually ported much of the MSP430 to the EK-LM4F232 dev kit in an early attempt, but again, that is not using the TI RTOS.

I will keep that in mind as an option though, but I am looking forward to the RTOS example from TI.
