How to define the value of rfkill Soft blocked

[f1engmin11]

my SDK is imx-yocto-L5.10.72_2.2.0，and test on imx8mm evk，when power on finish run rfkill list as below:

root@imx8mm-lpddr4-evk:~# rfkill list
0: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
1: brcmfmac-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: no

and how can I make Soft blocked to "no" by config yocto or other source code ?

instead of “echo 1 > /sys/class/rfkill/rfkill0/state”

can you help me?

Hello @f1engmin11,

I hope you are doing well.

how can I make Soft blocked to "no" by config yocto or other source code ?
->Please run the below command.
rfkill [options] command

Where put the below string as a command.
unblock index|type
(Enable the device corresponding to the given index. If the device is hard-blocked, e.g. via a hardware switch, it will remain  unavailable  though  it  is  now  soft-unblocked.)

I hope this answers your query.

Thanks & Regards,
