wifi azurewave iMX8M nano wifi direct

davidvescovi — Tue, 31 Aug 2021 01:39:04 GMT

i am using the iMXM nano evk with the supplied AzureWave wifi SD8987 and the Linux yocto L5.10.35 BSP.

I am trying to get wifi direct working as described in UM11490 section 2.6

I can tell the kernel driver loads correctly and I can command

wpa_supplicant -g/var/run/wpa_supplicant-global -D nl80211 –B &

to start the supplicant in the background.and it returns Successfully initialized.

when I do the next command:

wpa_cli -g/var/run/wpa_supplicant-global interface_add p2p0 "" nl80211 /var/run/wpa_supplicant

I get:

rfkill: Cannot open RFKILL control device
OK

I do not know if this is a problem or just a useless warning. I know the kernel defconfig has an option for RFKILL but I do not have it enable as I do not know if it needs to be implemented or if the AzureWave driver even supports it.

In any case I do not see my wifi direct advertising so I beleive something is missing.

Can someone help?

Hi David,

I test it, you don't need to care about the message "rfkill: Cannot open RFKILL control device".

I have the same messages here. The problem is the device does not show on the other peer device.
