LAUNCHXL-CC3235SF: flash AT command firmware from simplelink SDK, wifi scan can not find 5Ghz wifi ssid

Part Number: LAUNCHXL-CC3235SF

have checked the setting 5Ghz is enabled, what could be wrong the wifi scan not show the 5Ghz Wifi ssid?

  • Try to enable the 6G and the 5G channels in the code.

    - 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
    <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>

    you can also use the sl_WlanGet to check the default values.

  • thanks a lot, that works
