Hello all, Anyone who has implemented or can implement the WiFi Tethering function, please advise. I got the below information from Chat gpt. it is possible to control both AP (Access Point) and STA (Station) functionalities simultaneously without the need for a virtual wireless interface. Some w…

The phy is able to do both simultaneously but the virtual interfaces are still need for controlling the two interfaces separately from userspace. If you have connman installed the simplest method is to enable tethering mode, tether wifi on <ssid> <passphrase>, and then use connmanctrl to connect to …

Thanks for answering. I have one question. I keep getting errors in the wireless settings, but I think there is a problem with the kernel. Is the Yocto layer (“meta-murata-wireless”) added to SolidRun/meta-solidrun-arm-imx8?

It is not, we include the firmware tested for our devices directly in our BSP. Are you using our kirkstone meta-layer? What errors are you getting?

Yes, I’m using kirkstone-imx8m. root@imx8mpsolidrun:~# wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf Successfully initialized wpa_supplicant nl80211: kernel reports: Match already configured nl80211: kernel reports: Match already configured nl80211: kernel reports: Match already config…

This is most likely because connmand or networkmanagerd is already controlling the interface. If you want to manually configure the interfaces then you need to exclude them from being controlled by the networking daemons, or disable the networking daemons running.

I added the following command to the local.conf file when building core-minimal-image. DISTRO_FEATURES:append=" bluez5 bluetooth wifi iw wpa-supplicant packagegroup-tools-bluetooth" Isn’t this necessary? Is it possible to implement the wifi tethering function only with the initial core-minimal-im…

yes this is possible, but by default Yocto still has wpa_supplicant services that start on boot. You need to shutdown and or disable them if you want to run wpa_supplicant from the commandline.

Hello, Please check my commands for configuring WiFi tethering. #ifconfig wlan0 up #iw dev wlan0 interface add wlan1 type __ap #ifconfig wlan1 192.168.2.1 up #wpa_supplicant -D nl80211 -i wlan0 -c /etc/wpa_supplicant.conf -B #wpa_cli -p /var/run/wpa_supplicant -i wlan0 status #udhcpc -i wlan0…

yes, wpa_supplicant doesn’t handle the networking configuration. That is why using a networking daemon makes the entire setup much simpler.

Is the networking daemon you’re talking about networkmanager or nmi?

The default one shipped with NXP’s BSP is connmand, but NetworkManager is also an option I have documented how to include it at the end of the Kirkstone readme
