Introduction

The SimpleLink™ Wi-Fi® CC3200/3100 device family is a single-chip with built-in Wi-Fi connectivity, created for Internet of Things (IoT) purposes. The CC3100 device integrates all protocols for Wi-Fi and Internet, which greatly minimizes host MCU software requirements.

The Texas Instruments royalty-free SimpleLink host driver provides a complete software library, made especially for developing Wi-Fi® applications for the CC3100 network processor.

This document describes the Software Development Kit (SDK) version 1.3.0 for use with the CC3100 SimpleLink Wi-Fi Network Processor device mounted on the CC3100 BoosterPack development platform.

Getting Started

Please follow the on-line CC3100 Quick Start Guide to start using the CC3100 BoosterPack development platform.
Please download the CC3100 Getting Started Guide to get started with your project development.

  • Updated MQTT library and OTA Library for compatibility with Dropbox v2 API
  • Timer tick – The host driver checks the device tick count to internally determine certain timeouts. For non-os applications, it is mandatory to support this option in the builds.
  • Driver libraries required for example projects in SDK:
  • MSP430Ware for msp430 host device. Note this release tested with MSP430Ware_3_80_03_07
  • TivaWare for Tiva host device. Note this release tested with TivaWare_C_Series-2.1.4.178

    Errata

    The following section covers known issues and performance limitations with CC3100 production and pre-production devices.

    Hardware

    Pre-regulated 3.3v to Pin 47

    For preproduction devices connect an external pre-regulated 3.3v +/- 5% supply to pin 47 (VDD_ANA2). This adds 12mA average current and up to 100mA peak current over 20uSec to the total system current at 3.3V.

    The CC3100 BoosterPack version 3.3 already includes the correct supply configuration for the pre-production device and also adds a 10uF capacitor to filter the peak currents. No further action is required.

    The external 3.3V supply is not required in the CC3100 production device in which case pin 47 should be left not connected.

    Power consumption increase

    Power consumption of the CC3100 pre-production device in all active modes is 1-2 mA higher compared to the CC3100 production devices

    Title DHCP Server: Same address is provided if pool is full
    Description When all of the addresses in the DHCP server pool are assigned, it will continue to offer and assign the last address in the pool to new connected station
    Impact Low impact – The DHCP lease time is not kept for the last disconnected STA.
    Since only one client can connect at a time to the AP the STA will still get an IP and connect

    Title HTTP Server: SSID is limited to 16 characters
    Description From the HTTP web pages only the SSID string is limited to 16 characters instead of 32 characters
    Impact Med impact – Can’t add a SSID string longer than 16 characters from the HTTP using the device tokens
    Workaround Only the device tokens are limited – implementing user tokens for this field can overcome the issue

    Description From the HTTP web pages only the password key is limited to 32 characters instead of 63 alphanumeric characters
    Impact Med impact – Can’t add a password key longer than 32 characters from the HTTP using the device tokens
    Workaround Only the device tokens are limited – implementing user tokens for this field can overcome the issue

    Title HTTP Server: Sending a page with no checkbox return “HTTP- No Content Length” message appears
    Description The internal web pages of the device returns “HTTP- No Content Length” if no checkbox is set
    Impact Low impact – HTTP pages design
    Workaround Insuring that the form will never be empty by adding to the HTML form (that is sent via an HTTP POST) an additional input (can be set with type=hidden)

    Driver Library Compatibility Known Issues

    Version TivaWare_C_Series-2.1.4.178
    Title IAR Compiler version 8.10 and later will generate linker warnings for pre-compiled driverlib.a library inside TivaWare version TivaWare_C_Series-2.1.4.178
    Description The precompiled driverlib.a library was compiled using an EWARM IAR version of 7.80 or earlier in which the size of wchar_t datatype does not match the size in later IAR versions.
    See the IAR information Center for ARM for additional details.
    Impact Please refer to the IAR information Center for ARM for impact details
    Resolution To avoid any impact on the user application, the developer should recompile driverlib.a as a static library with a newer version (8.11 or later) in IAR.

    Migrating from Host Driver Version 1.0.1.6 to Version 1.0.1.11

    The new Host driver checks the host tick count to internally determine certain timeouts and error detection. To support the entire error handing mechanism, accurate timestamp service should be implemented in the Host application. For non-os applications, it is mandatory to support this option in the builds. This section describes the minimal changes required in order to use the new Host driver.

    Event Handler

    Ensure sl_GeneralEvtHdlr is registered. This handler will enable the application to be notified on general/fatal driver errors and therefore it is mandatory. If the application already registered to this handler the handler should check for the new errors.

    System Time

    The Host driver calls sl_GetSystemtime to get the current tick count. In addition, the macros: SL_TIMESTAMP_TICKS_IN_10_MILLISECONDS and SL_TIMESTAMP_MAX_VALUE must be defined in order for the internal host driver logic to trigger a timeout.
