  1. I am working on code related to sending an email through cc3100booster and msp432p401r. I am having an issue in connectivity of wifi in the module when the wifi connection code is provided in void setup(). I am providing mobile's hotspot and it gets connected and disconnected periodically. I require an continuous connection.

    When the wifi connection code is written inside loop(), the connection problem is solved but a newer issue is arised i,e, the program is running for email but not for the server [In server program i am sending temperature and pulse count value to thingspeak.com to get a graphical representation of my data.]

    moreover, despite of being present in loop, it executes only once. its a complete arcane issue for me. I am linking code below. please help me out with this.

    #define TEMBOO_ACCOUNT "xxxxxxx"  // your Temboo account name
    #define TEMBOO_APP_KEY_NAME "xxxxxxx"  // your Temboo app name
    #define TEMBOO_APP_KEY  "xxxxxxxx"  // your Temboo app key
    #define WIFI_SSID "xxxxxx"   //hotspot name
    #define WIFI_PASSWORD "xxxxxxx"   //hotspot password
    #ifndef __CC3200R1M1RGC__
