Hey guys:

We need to completely turn off the TX2 wifi & Bluetooth signal to passed CE certification.

I tried:

sudo rfkill block wifi  
sudo rfkill block bluetooth

But It doesn’t make sense.
What supposed I do ?

Thanks for your great help.

If you want the full block from hardware.

method 1. Disable below in tegra_defconfig
CONFIG_BCMDHD=m
CONFIG_BCMDHD_SDIO=y
CONFIG_BCM4354=y
CONFIG_BCMDHD_FW_PATH=“/lib/firmware/brcm/fw_bcmdhd.bin”
CONFIG_BCMDHD_NVRAM_PATH=“/lib/firmware/brcm/nvram.txt”
CONFIG_BCMDHD_HW_OOB=y
CONFIG_DHD_USE_SCHED_SCAN=y
CONFIG_BCMDHD_ES4_NVRAM_PATH=“/lib/firmware/brcm/nvram_murata_4359_b1_es4.txt”

method 2.
You could also disable the gpio pin “wifi-enable” and “wifi-wake-ap” from device tree.
For wifi-enable, please remove “output-high;”

Hi WayneWWW:

Modify the config as above ,then the RF signal won’t work,is that true ?
