    • Copy and save the key in a text file.
    • Also note your FeedID. In this application note case, it is 118437. Make a note of it.

Step 5

  • Import this project into CCS and open main.c
    • Look up UARTSend((unsigned char *)"AT+WA=WIFI_NAME\r", 1); and replace WIFI_NAME with wireless name of your network.
    • Look up UARTSend((unsigned char *)"AT+WWEP1=WIFI_KEY\r", 1); and replace WIFI_KEY with the wireless network WEP Key.
    • Look up UARTSend((unsigned char *)"FEED_ID.csv HTTP/1.1\r\n",1); and replace 118437 with the feed id you noted in Step 4.
    • Look up UARTSend((unsigned char *)"X-ApiKey: API_KEY\r\n",1); and replace the key with the API_KEYyou noted in Step 4.

Compile the program and download it to the Launchpad.

Step 6

  • Open a serial terminal and connect to the Launchpad @115200, no parity, 8 bits and 1 stop bit.
  • Click the run arrow in CCS. You should see the following details pop up as the wifi chip connects to Cosm.
