WL1837MOD: changing per_chan_pwr_limit_arr_11abg parameter with wlconf

Part Number: WL1837MOD

hello

I want to change the Tx power(reduce the power) for the 1837 module we are using. How do i set the per channel power limit array using the wlconf utility and create a new conf.bin file ?

Using the below command

./wlconf -i /lib/firmware/updates/ti-connectivity/wl18xx-conf-ti.bin -o /lib/firmware/updates/ti-connectivity/wl18xx-conf-ti.bin -s wl18xx.phy.per_chan_pwr_limit_arr_11abg=0x58, 0x88, 0x88, 0x78, 0x88, 0x88, 0x78, 0x88, 0x88, 0x78, 0x88, 0x88, 0x78, 0x88, 0x18, 0x78, 0x88, 0x88, 0x78, 0x88, 0x82, 0x78, 0x88, 0x88, 0x78, 0x88, 0x88, 0x78, 0x88, 0x88, 0x78, 0x88, 0x88, 0x78, 0x88, 0x88, 0x78, 0x88, 0x88, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xf7, 0x22, 0x22, 0xff, 0xff, 0xff, 0xf7, 0x22, 0x22, 0xff, 0xff, 0xff, 0xf7, 0xff, 0xff, 0xff, 0xff, 0xff, 0xf7, 0xff, 0xff, 0xf4, 0x44, 0xff, 0xf4, 0x44, 0xff, 0xf4, 0x22, 0x22, 0xf4, 0x22, 0x22, 0xf6, 0x44, 0x44, 0xff, 0x44, 0x44, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0x55, 0xff, 0x44, 0x55, 0xf4, 0xff, 0xff, 0xff, 0x33, 0x22, 0xff, 0x33, 0x22, 0xff, 0x66, 0x66, 0xff, 0x44, 0x66, 0xf6, 0xff, 0xff, 0xff, 0xff, 0xff
