    Internal Structure of ti wifi module

    Function Upgrade of ti wifi module

    The above is function structure chart of C322 firmware V2.0.Blue part is for original function, orange for new features of V2.0. New features of firmware V2.0 includes double serial,three links,PC1 Encrypt,SSL encryption submission,http and Websocket communication mode.

    Double Serial,Three Links

    C322 has double serials and three network links.
    UART 0 supports two network links and one link supports TCP Server;UART 1 supports one network link.
    Application Example:
    1.Communication with two servers:two UARTs connect with two different servers and receive different commands for the servers;
    2.Data backup and remote debugging:serial data sent to the two servers by using two network links of UART 0;
    3.TCP Server and TCP Client can work at the same time;

    Security of Communication Data of ti wifi module

    Firmware V2.0 has two encryption communication methods:
    PC1 Encrypt:wifi module receives data,encrypts the data with PC1 Encrypt and sends the data to server; SSL Client:use SSL Client to submit data to server;

    Data Submitted to Web Server Directly

    Built-in Webpage with Custom Extensions

    C322 built-in webpage supports user-defined functions.
    C322 supports function of Ethernet to serial, which adopts HTML5 Websocket technology. Combined with custom webapge function, User can design built-in webpage to realize webpage control and data acquisition according to project requirement.

    Function and Detail of ti wifi module

    • High-speed Baud Rate : serial baud rate up to 3Mbps; have high speed in large amount of data transmission applications like WIFI printer,WIFI serial camera and WIFI high-speed data acquisition.
    • Onekey WIFI Connection : support two fast networking ways–“SimpleLink” and “UsrLink”;perfectly solve problems of complex networking operation in smart home applications.
    • RegistryPackage Function : send registry data package immediately after TCP connection,which is convenient for server identifying and processing;registry data package supports custom ID and MAC.
    • Baud Rate Sync : support using USR Visual Serial Software(USR-VCOM).

    Outstanding Performance of TI wifi module

      • In industrial field:positioning low power and industrial-grade WIFI module; can adapt to industrial environment of – 40 ~ 85 °C; TI’s great repetation also can guarantee the stability of core solutions in industrial environment; Amazing power control can adapt to any requirements.
      • In civilian field:positioning high-end intelligent civil products; support SimpleLink and UsrLink onekey APP networking mode.

    Test Report of ti wifi module

      • After go into sleep mode,C322 will go through three stages:
        ① average current of 3.5ma in sleep mode;② after data sent to wifi module,wifi module wakes up quickly and begins to send data;③ if no data sent to wifi module within 10s,wifi module will enter sleep mode again
      • Data sending test:
        network termination sends 34000 bytes at a time and serial receives 34000 bytes;
        network termination data wakes up wifi module and transmits to serial without data loss.
