Colibri imx8x, High-throughput Access Point

My platform: Iris 2.0 + Colibri iMX8 QuadXPlus 2GB Wi-Fi / Bluetooth IT

Based on How to Setup Wi-Fi Access Point Mode (Linux) | Toradex Developer Center

Is possible set " High-throughput Access Point" on Colibri imx8x ?

After add ht_capab and start hostapd /etc/hostapd.conf I have:

Driver does not support configured HT capability [RX-STBC*]
uap0: interface state COUNTRY_UPDATE->DISABLED
uap0: AP-DISABLED
uap0: interface state DISABLED->DISABLED
uap0: AP-DISABLED
uap0: CTRL-EVENT-TERMINATING
hostapd_free_hapd_data: Interface uap0 wasn’t started

And AP won’t start :frowning:

Hi @MariusM !

Can you please share the output of tdx-info? (reference: Getting Device Information with Tdx-Info | Toradex Developer Center)

Which driver are you using? Is it the proprietary one? (reference: GitHub - toradex/meta-toradex-wifi: This repository contains recipes and meta-data to integrated the NXP proprietary wireless drivers (also called mlan or the C-Driver) into the Toradex BSP for SOMs containing the Azurewave 88W8997 chip.)?

And could you please elaborate on why you would need to enable the “High-throughput Access Point”?

In the mean time, I will try to find out if there is actual support for such option.

Best regards,

At this moment I have prototypes with 6.3 but think update to 6.4

I thought that the drivers for the built-in Wifi card were already in the system image.
Maybe I didn’t read something.
I will investigate this thread

And could you please elaborate on why you would need to enable the “High-throughput Access Point”?

I want to send the image to many devices in real time (or almost) via WiFi
I wanted to check this option to see if it would be better for my performance problems

What features did you specify in ht_capab= line and what capabilities does iw phy report? hostapd will fail to start if specified feature isn’t available from driver. Perhaps try this nice Gateworks script to craft your hostpad.conf. Bit outdated but still useful:
hostapd-conf

Hi @MariusM !

The images have already the open source drivers for the Wi-Fi/Bluetooth module. I just asked if you are having issues with the open-source drivers or with the proprietary ones from NXP.

Thanks for sharing your context. Could you please be more specific about your requirements? Also, what are exactly those performance problems you are facing? The more specific is the information you can share, better we can understand your use case :slight_smile:

Also, please share a simple way of reproducing the problems you are having.

Best regards,
