How to set 40MHz in 2.4G band with NX611 in STA mode?

Sona NX611

Answer

To support this feature, need to upgrade the SW to 13.24.0.20 release.

By default, only 20MHz enabled in 2.4GHz band.

To enable 40MHz bandwidth, need to add one more setting, httxcfg_2 as 0x010062 in 

/lib/firmware/nxp/wifi_prod_serdev_params.conf , as below

SDIW612 = {

    #Firmware to load via Wi-Fi interface

    #  wifi     : sd_w61x:wlan.bin.se

    #  wifi & bt: sduart_nw61x.bin.se

    fw_name=nxp/sduart_nw61x_v1.bin.se

 

    #Interfaces: Bit 0: STA, Bit 1: uAP, Bit 2: WIFIDIRECT

    drv_mode=1

 

    #WiFi Independent Reset (Requires using sd_w61x firmware)

    # 0xFF00:Disable, default

    # 0xFF01:Out-of-Band

    # 0xFF02:In-Band

    #indrstcfg=0xFF02

 

    #Self Managed Regulatory (Do not change)

    cntry_txpwr=2

 

    #Name of managed interface, default is mlan

    sta_name=wlan

 

httxcfg_2=0x010062

 

    #Debug Level

    drvdbg=7

}
