CCS/LAUNCHXL-CC1310: How to set symbol rate 200kbps from 50kbps

Part Number: LAUNCHXL-CC1310
Other Parts Discussed in Thread: CC1310, CC2650, CC1352P

Tool/software: Code Composer Studio

Dear sir,

In my application i am using CC1310 launch pad with 50k bps symbol rate.  sdk is \ti\simplelink_cc13x0_sdk_3_10_00_11. i want to change  bit rate from 50 k to 200k. But this is failing in chip validation check. 

/***************************************************/

case EasyLink_Phy_2_4_200kbps2gfsk:
if((ChipInfo_GetChipType() == CHIP_TYPE_CC2650))
{
useDivRadioSetup= false;
rfConfigOk = true;
}

/***************************************************/

In Initialization,  i have already changed selection mode as below:

/***************************************************/

EasyLink_Params_init(&easyLink_params);

easyLink_params.ui32ModType=EasyLink_Phy_2_4_200kbps2gfsk;
/*
* Initialize EasyLink with the settings found in easylink_config.h
* Modify EASYLINK_PARAM_CONFIG in easylink_config.h to change the default
* PHY
*/
if (EasyLink_init(&easyLink_params) != EasyLink_Status_Success){
while(1);
}

/***************************************************/

I have generated relevant file from smart studio 7. 

Kindly provide your support. 

Thanks,
AG

    Hi Anil,

    It looks like you've chosen the Phy settings for 2.4Ghz 200kbps data rate, IEEE 802.15.4g GFSK. The CC1310 doesn't support 2.4GHz, so you will need to instead select:

    easyLink_params.ui32ModType= EasyLink_Phy_200kbps2gfsk;

    Thanks,

    Alexis

    Hi Alexis,

    Regards for your reply. I would like to add more in my last query. 

    I have done suggested necessary changes  regarding correct mode configuration and  have following observations:

    1. I have generated smartrf_settings.h and smartrf_settings.c file from Smart RF studio 7 "200kbps 2GFSK 70k deviation" option.

    2. selected  "EasyLink_Phy_200kbps2gfsk"  mode  in example code rfEasyLinkTx

    /***************************************************************/

    easyLink_params.ui32ModType=EasyLink_Phy_200kbps2gfsk;
    /*
    * Initialize EasyLink with the settings found in easylink_config.h
    * Modify EASYLINK_PARAM_CONFIG in easylink_config.h to change the default
    * PHY
    */
    if (EasyLink_init(&easyLink_params) != EasyLink_Status_Success){
    while(1);
    }

     /***************************************************************/

    3. Still the condition of chip validation check is failing inside the function EasyLink_init(&easyLink_params) 

    /***************************************************************/

    case EasyLink_Phy_200kbps2gfsk:
    if((ChipInfo_GetChipType() == CHIP_TYPE_CC1312) || (ChipInfo_GetChipType() == CHIP_TYPE_CC1352) || 
    (ChipInfo_GetChipType() == CHIP_TYPE_CC1352P))
    {
    #if !defined(Board_CC1352P_4_LAUNCHXL)
    // This mode is not supported in the 433 MHz band
    useDivRadioSetup= true;
    rfConfigOk = true;
    #endif
    }
    break;

    /***************************************************************/

    4. My question is , if I have generated smartrf_settings.h and smartrf_settings.c file from Smart RF studio 7 "200kbps 2GFSK 70k deviation" option, then is it required to select mode EasyLink_Phy_200kbps2gfsk??

    5. What should i do in case of point  number 3?

    Kindly provide your valuable suggestion .

    Thanks,
    AG

    Hi Anil,

    Try adding SUPPORT_PHY_200KBPS2GFSK to your predefined symbols. you can do this by navigating to Project>Properties>Build>ARM Compiler>Predefined Symbols and adding it to the list. 

    Thanks,

    Alexis
