Other Parts Discussed in Thread: CC3100, CC3100SDK

Hi,

I want to transfer data between two CC3100 boosterpack,where i am connecting both the cc3100 to TM4c1294xl launchpad.There is no wi-fi router so station mode can be eliminated.

I have some queries where i am beginner to cc3100 usage.

1)Which mode i should cofigure for this application?? (AP,P2P) 

2)I want to code it using TI-RTOS. Is there sample code provided in the CC3100SDK??

3)Which transport layer i should use?? (TCP,UDP or etc )

    Hi,

    1) You can use either of the 2 modes (P2P/AP). Both of these mode for use case.
    2) The example is part of 'TI-RTOS for Tiva C' package.
    3) Use of TCP/UDP will depend on the use case. If you want the reliability then you should use TCP.

    Thanks for the reply.

    I have problem in debugging the code,i tried to use the code provided in the application report attached.

    but when i am trying to use the code wifi_node_ap_tirtos,i am getting the following errors.

    error #10008-D: cannot find file "C:/ti/tirtos_tivac_2_12_01_33/products/TivaWare_C_Series-2.1.0.12573c\driverlib\ccs\Debug\driverlib.lib"

    error #10010: errors encountered during linking; "wifi_node_ap_tirtos.out" not built

    1)the point here is when i checked the ti folder, i find the rtos version installed is tirtos_tivac_2_14_04_31 and even i checked the properties of the project which doesn't contain folder in the ARM linker path related to tirtos_tivac_2_12_01_33 version.

    2)I find TCP echo example in RTOS for tiva-c,should i dump the same code in both the launchpads?

    Regards,

    Hi,

    The error is saying the .lib file cannot be found at that folder location. Do you have that .lib file in that folder location? if not, then I suspect you did not install TI-RTOS for Tiva MCU's.

    Thanks Markel,
    I have resolved the error.Can i know which example should i follow for my application?
    I am totally confused in it. as i earlier mentioned i am using the code provided in the application report.wifi_node_ap_tirtos
    here are my few questions please help me out of this.
    1)Should i have to burn the same code in both the cc3100 connected launchpads??
    2)what changes should i make so that cc3100 on one board should connect to cc3100 on other.. when i burn the code mentioned in "wifi_node_ap_tirtos" it sets both the cc3100 in AP mode.
    3)how can i come to know that both the devices are connected?
    Looking for your reply.
    Thanks
