CC3200 : TCP socket server and HTTP client ( For rest APIs) simultaneously

Hardik Madhu75

Other Parts Discussed in Thread: CC3200

Hey everyone,

We are planning to use "SimpleLink Wi-Fi CC3200 LaunchPad". We want to have a TCP socket server that connects to multiple clients on local network and also have an HTTP client that sends collected data to a REST API server.

I am new to Network programming and to TI-RTOS NDK. I was wondering whether it is possible to do this or not, having a TCP socket server and having an HTTP client (a UDP socket client internally perhaps?) simultaneously. I've read through the NDK guide, TI-RTOS guide and a lot of e2e posts and I think it's possible, but I do need to be sure before beginning any kind of development.

Any kind of response or guidance to any kind of example is much appreciated.

Regards,

Hardik Madhu

Hi,

Yes this is possible. CC3200 supports up to 8 BSD sockets at one moment. But do not forgot that TI-RTOS NDK is not used for CC3200. CC3200 have in NWP (network processor) integrated own TCP/IP stack. From this reason your application processor (Cortex M4 for your code) don't need serve TCP/IP stack and use simple BSD sockets. Socekts are available via sl_ API commands.

Hi Jan,

Thanks you so much for quick response.

Just to clarify, I do still need to use the TI-RTOS but not the NDK part of it. If that is true, can you please guide me to documentation / Developer Kit guide for developing Network layer applications for CC3200. I have only found the NDK guide so far.

Also, I am adding another question. Are you aware if it is possible have callbacks when data is received by some socket, so that we don't have to keep poling the socket.

Thanks and Regards,
Hardik Madhu

Hi Hardik,

For CC3200 you can use NON-OS application, TI-RTOS or FreeRTOS. Network stack is used from NWP and is based on BSD socket interface.

- Good development kit for start - www.ti.com/.../cc3200-launchxl
- Project 0 example, how to start with CC3200 and Code Composer Studio developed IDE - www.youtube.com/watch
- Good description of Simple Link API - www.ti.com/.../litabsmultiplefilelist.tsp
- SDK - www.ti.com/.../cc3200sdk
- Wiki - processors.wiki.ti.com/.../CC31xx_&_CC32xx

Callback for received data are not supported, because this is not part of BSD sockets. You can use blocking and non-blocking sockets.
