[imx8m] wpa_supplicant mesh support

[jhii6488_vine]

I tried changing wifi to mesh mode through network manager.

Below is the command I used.

==============================================================================

root@imx8mq-var-dart:~# nmcli con add type wifi ifname wlp1s0 ssid Drone2
Connection 'wifi-wlp1s0' (5037e96e-1e55-41e9-855d-21ba818c3400) successfully added.
root@imx8mq-var-dart:~# nmcli con edit wifi-wlp1s0

===| nmcli interactive connection editor |===

Editing existing '802-11-wireless' connection: 'wifi-wlp1s0'

Type 'help' or '?' for available commands.
Type 'print' to show all the connection properties.
Type 'describe [<setting>.<prop>]' for detailed property description.

You may edit the following settings: connection, 802-11-wireless (wifi), 802-11-wireless-security (wifi-sec), 802-1x, ethtool, match, ipv4, ipv6, tc, proxy

Error: Connection activation failed: No suitable device found for this connection (device wlp1s0 not available because profile is not compatible with device (wpa_supplicant does not support Mesh mode)).

==============================================================================

I set it like the following in the menuconfig.

CONFIG_MAC80211_MESH=y

If Wpa_supplicant does not support mesh mode as in the error, can I not use mesh mode?

[synaption]

I am confused.  Is this a limitation of the imx linux kernel, or is this just a limitation on the driver for the specific wifi module that comes on the imx boards?  I am currently getting the error wlan0: Driver does not support mesh mode with a usb wifi device.

Hi Hyein

unfortunately nxp wifi drivers do not support mesh mode, supported functionality

is described in nxp linux official documentation   NXP Wi-Fi Driver Features and Release Notes

Best regards

I am using Atheros QCA9882 chipset(wle600v5-27), driver is ath10k. When I printed out the mode supported by wifi on the board, it was as follows.

-------------------------------------------------------------------------------
WIFI-PROPERTIES.WEP: yes
WIFI-PROPERTIES.WPA: yes
WIFI-PROPERTIES.WPA2: yes
WIFI-PROPERTIES.TKIP: yes
WIFI-PROPERTIES.CCMP: yes
WIFI-PROPERTIES.AP: yes
WIFI-PROPERTIES.ADHOC: no
WIFI-PROPERTIES.2GHZ: no
WIFI-PROPERTIES.5GHZ: yes
WIFI-PROPERTIES.MESH: yes
WIFI-PROPERTIES.IBSS-RSN: yes
-------------------------------------------------------------------------------

If I want to communicate with wifi<----->wifi other than mesh mode, can you tell me what can I do?

However, I cannot use Access Point <-----> Station mode.
