    emPower emNet WiFi add-ons allow you to easily evaluate multiple WiFi solutions by simply exchanging one piece of hardware and some lines of code.

    The code to exchange usually includes one emNet configuration file (basically only two lines of code need to be changed to select another driver) and porting of the host interface (typically SPI send/receive) routines.

    Porting to your own customized hardware can be done easily as well by adopting these porting layers to your requirements based on the existing emPower samples.

    Available modules

    The following WiFi modules are available as emPower eval board add-ons and can be easily evaluated using emNet WiFi drivers.

    Microchip ATWILC1000

    wifi module atwil

    Description: The Microchip ATWILC1000 is a link controller meant for usage with third party TCP/IP stacks providing IEEE 802.11b/g/n WiFi support in a 2.4GHz band.

    The firmware of the ATWILC1000 is loaded from the host MCU. This provides an easy way of updating the WiFi module firmware together with the host MCU firmware. The WiFi firmware can be loaded from an externel source as well.


    Host Interface:

    • SPI
    • UART

    Memory Requirements:

    ROM: App. 7kBytes + app. 168kBytes WiFi firmware


    Known Limitations:

    Requires ASF (Advanced Software Framework) >= v3.40 to work reliable with Access Points that use MIMO.

    Longsys/Arrow GT202

    wifi module all joyn

    Description: The Longsys/Arrow GT202 is a controller supporting IEEE 802.11b/g/n WiFi networks
    in a 2.4GHz band.

    The WiFi firmware comes pre-loaded in the module keeping it away from the
    host MCU firmware. The WiFi module can be updated manually.


    Host Interface:

    • SPI
    • UART

    Memory Requirements:

    ROM: App. 29kBytes


    Known Limitations:

    No support to enable custom multicast filters (no multicast support). Filters for multicast
    required for basic IPv6 operations seem to be enabled in the module.

    These are limitations of the module we came across and found no solution for, not limitations or known problems (Errata) published by the module manufacturer.

    Redpine Signals RS9113

    redpine

    Description: The Redpine Signals RS9113 is a controller supporting IEEE 802.11b/g/n WiFi
    networks in a 2.4GHz band. Support for the 5GHz band is a build option for the
    module. Modules that support the 5GHz band offer offer 802.11n at 2.4GHz/5GHz
    and 802.11a at 5GHz. Connect-io-n RS9113 and WiSeConnect RS9113 as well
    as modules compatible to these product familys are supported.

    The WiFi firmware comes pre-loaded in the module keeping it away from the
    host MCU firmware. The WiFi module can be updated manually.


    Host Interface:

    • SPI
    • UART
    • SDIO
    • USB

     


    Memory Requirements:

    ROM: App. 5kBytes


    Known Limitations:

    BSSID (HW addr. of AccessPoint) can not be retrieved. BSSID of pre-connect scan
    needs to be assumed for AP BSSID.

    These are limitations of the module we came across and found no solution for, not limitations or known problems (Errata) published by the module manufacturer.
