BOOSTXL-CC3135: Configuring Band frequency

Marvin Gasis Arcangel

Part Number: BOOSTXL-CC3135

Hi Team,

Can you please help with the inquiry below?

I want to be able to dictate which band to use (either 2.4Ghz or 5Ghz) by coding it into Code Composer Studio and not using the network terminal.

Also, is there an example in the SDK that I can refer to?

Thanks and regards,

Marvin

you can set the channels to use in scan (which will impact the connection as well) using the sl_WlanSet. Check the following options:

    - SL_WLAN_GENERAL_PARAM_OPT_SCAN_PARAMS:
    \code
        SlWlanScanParamCommand_t ScanParamConfig;
        _u16 Option = SL_WLAN_GENERAL_PARAM_OPT_SCAN_PARAMS;
        _u16 OptionLen = sizeof(ScanParamConfig);
        // 2.4G channels bits order:  1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 
        
        ScanParamConfig.RssiThreshold = -70;
        ScanParamConfig.ChannelsMask = 0x1FFF;
        sl_WlanSet(SL_WLAN_CFG_GENERAL_PARAM_ID, &Option, &OptionLen, (_u8 *)&ScanParamConfig);
    \endcode
    <br>

        - SL_WLAN_GENERAL_PARAM_OPT_SCAN_PARAMS_5G:
    \code
        SlWlanScanParam5GCommand_t ScanParamConfig5G;
        _u16 Option = SL_WLAN_GENERAL_PARAM_OPT_SCAN_PARAMS_5G;
        _u16 OptionLen = sizeof(SlWlanScanParam5GCommand_t);
        // 5.0G channels bits order: 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132,
        //                          136, 140, 144, 149, 153, 157, 161, 165, 169, 184, 188, 192, 196 
        
        ScanParamConfig5G.ChannelsMask = 0x0000000F; // Select ChannelsMask for channels 36, 40, 44, 48 
        ScanParamConfig5G.RssiThreshold = -70;
        sl_WlanSet(SL_WLAN_CFG_GENERAL_PARAM_ID, Option, OptionLen, (_u8 *)&ScanParamConfig5G);
    \endcode
    <br>

The 5G Band can be enabled/disabled using the following command (but this can't be done for 2.4):

	- SL_WLAN_GENERAL_PARAM_OPT_ENABLE_5G
	\code
	    _u8  Enabled5GStatus = 1;
	    _u16 Option = SL_WLAN_GENERAL_PARAM_OPT_ENABLE_5G;
	    _u16 OptionLen = sizeof(_u8);

	    ret = sl_WlanSet(SL_WLAN_CFG_GENERAL_PARAM_ID, Option, OptionLen, (_u8 *)&Enabled5GStatus);
	\endcode
