This sample application demonstrates the capability of CC3100 device to work as a web-server and allowing the end-users to communicate w/ it using standard web-browsers.

For more information refer to HTTP Server section of Programmers Guide

NoteNote: This wiki page is only applicable for CC3100-SDK v1.0.0 and upward releases. For documentation on older SDKs' examples, refer corresponding file in <cc3100-sdk-installation-location>\cc3100-sdk\docs\examples\

Application details

This application configures the CC3100 in AP mode with a pre-defined SSID-NAME and uses the sample HTML pages to toggle on-board LEDs. GET and POST tokens are used to get the LEDs' status and toggle the LEDs respectively. Clients can connect to CC3100 and request for web-pages using the IP of device from any standard web browser. The HTML pages provided with the sample application needs to be downloaded on serial-flash using CCS_UniFlash utility. The authentication parameters and domain name can be changed using corresponding host-driver APIs.


  • Flash main.html and blink_led.html on serial-flash by following the below steps:
    1. Open the Configuration-file at <cc3100-sdk-installation>/examples/http_server/uniflash_template/http_server.ucf in Uniflash
    2. Flash the files on the device. Uniflash User Guide has detailed instructions for flashing
  • Configure the terminal program for seeing the logs - CC3100 & CC3200 Terminal Setting has detailed instructions for flashing
  • Edit sl_common.h and modify the value for SSID_AP_MODE, PASSWORD_AP_MODE and SEC_TYPE_AP_MODE.
  • Build and launch the project. CC3100 will come-up in AP mode w/ the value set above as its SSID name
  • Connect a client w/ CC3100 using its SSID name
  • Open a web-browser on the client and enter the IP of CC3100 in the client's address bar
    • Default IP address is
    • Alternatively, '' can also be entered for accessing the web page
