    FAQ

    For SSD45N/MSD45N in Linux platform, if during the regulation test, need to adjust 3dB in 2.4G, how to set this number during the driver initialization so that the TX power will match what they test in regulation test?

    SMU is the safest way to set it.

    # smu_cli set tx-max-bg 6

    # smu_cli get tx-max-bg

        Reg Domain:  WW

        BG Antenna Adj: 3 dB

        A  Antenna Adj: 0 dB

    Remember the  value is in ½ db increments so you need to use 6 to get 3 dBm. 


    Also fw_setenv is able to set it as well.
    rfPowerAtten2=6
