Tackling core challenges in the IoT over Wi-Fi® December 13, 2016 Calum Barnes, Xively Beatrice Fankem, Texas Instruments Hello, My name is Beatrice Fankem, SimpleLink Wi-Fi Product Marketing Engineer. The Internet of Things (IoT) is becoming an increasingly large part of our everyday life. There are several challenges that must be addressed when designing a product that can be remotely monitored or controlled. In this session, we will address how Simplelink Wi-Fi and Xively partnered to tackle those core challenges.

Enabling technology in many markets Wearables • Healthcare • Smart manufacturing • Smart Cities • Automotive • Building & Home automation Markets Challenges Security Complexity Power is critical Connecting to the cloud Sensing a complex environment In our daily lives, whether it be in the wearable segments, the healthcare industry or within building automation, people and machines use wireless devices to constantly exchange information. The challenges Information such as Security, The complexity of the technology

The Cloud is where the information is stored, processed into analytics and where commands can be sent back to the nodes or interface with a Smartphone The Cloud servers need to be always on and perform parallel processing and handle mass storage TI has something in every segment Analog Signal Chain Analog Signal Chain Power Management

Wi-Fi® doesn’t have to be complicated SimpleLink™ Wi-Fi CC3200 makes it easy

The SimpleLink™ embedded Wi-Fi® revolution Traditional Wi-Fi solutions are designed for powerful microprocessors User Application Application Protocols Traditional Wi-Fi TLS/SSL SimpleLink CC3200 offloads the host processor of all Wi-Fi functions TCP/IP Wi-Fi MAC Less expertise Lower system cost Faster time to market Supplicant SDIO Wi-Fi Baseband Wi-Fi Driver Wi-Fi Radio SDIO Driver High MIPS/Memory MPU SimpleLink Wi-Fi CC32xx Wi-Fi Baseband Wi-Fi MAC Wi-Fi Radio Wi-Fi Driver Supplicant TCP/IP TLS/SSL Application Protocols MCU: ARM® Cortex M4 256KB RAM User Application SPI or UART Driver SimpleLink Driver Earlier Wi-Fi solutions have been designed for powerful mircroprocessors, within which the internet protocols an ddrivers had to be integrated. SimpleLink Wi-Fi family of devices offloads the host of all Wi-Fi and internet protocols. The highly integrated CC3200 provides a complete solution that will lower the developer's system cost, and enable a faster time to market. Integrated System-on-Chip, Wireless MCU

Everything listed in gray, the hardware and firmware, is integrated within the CC3100 device. We expose the user to less than 60 API functions in the form of a simplelink host driver [ask beatrice about <60]. The simplelink host driver has a very small memory footprint. [3100 depends on host RAM, 3200 memory in RAM is 256k] Network Processor TCP/IP Stack WLAN MAC & PHY Platform Code TI Code Customer Code

Simple Wi-Fi® Control Examples: Start/Stop network Processor sl_Start, sl_Stop Connect to an Access Point sl_WlanConnect() (auto-connect on startup: sl_WlanPolicySet(), sl_WlanProfileAdd()) Change mode (Station, Access Point, Peer to Peer) sl_WlanSetMode()

Establishing a Wi-Fi® Connection APIs to Call What you provide What the SimpleLink™ NWP does Sl_wlanConnect Access point credentials Name (SSID) Password (key) Establishes the connection, including the DHCP handshake process. Maintains Wi-Fi connection to access point of given security. Notifies when connected or disconnected Access point security type Ex: Open, WPA, WPA2 sl_socket Choice of protocol Ex: TCP, UDP, TLS, etc. Opens communication channel to peer (server, device, etc.) at specified address Sl_connect The internet address to communicate with Ex: 192.168.1.123:80 Ex: www.ti.com Your Data Sends/receives your data to/from the peer over the internet SL_Socket Domain, Type, Protocol  Sl_connect: _i16  sd, const SlSockAddr_t *  addr, _i16  addrlen 

Internet Security - Made Easy Unsecured socket connection Secured socket connection SlSockAddrIn_t Address; int SockID; Address.sin_family = SL_AF_INET; Address.sin_port = sl_Htons(PORT); Address.sin_addr.s_addr = sl_Htonl(IP_ADDRESS); SockID = sl_Socket(SL_AF_INET, SL_SOCK_STREAM, 0); sl_Connect(SockID, ( SlSockAddr_t *)&Address, sizeof(SlSockAddrIn_t)); SockID = sl_Socket(SL_AF_INET, SL_SOCK_STREAM, SL_SEC_SOCKET); The protocol family of the socket Ex. AF_INET for IPv4 IPv4 AF_RF for transceiver mode
