Colibri iMX7 with LM816 as Access Point

Hi there,

with the LM816 as Wifi Access Point on a Colobri iMX7 we want that other Devices can join the Colobri and get serve some webpages from the Colobri.

At first is this possible ? And if yes, do you got a hint how to configure this scenario or is there a resource for this kind of information in the web. I try to figure out how it become to work but got no success.

Thx in advance.

hi @david_korm

You can check if the Access Point is supported by launching the following command: iw phy | grep Supported -A 5 and looking for Supported interface modes. I checked with LM816 and Bsp 2.8b4. There the access Point mode is not supported.

If you are interested to get a Wifi Solution with Access Point Mode, then you should use iMX6ULL.

Best regards, Jaski

Hi @jaski.tx

thank you for your answer. Unfortunately we cannot change the module. Now we got to question:
First, is the USB device which have ac Access Point Mode ?
And second, is it possible to built up with the LM816 an ad hoc network ?

And could I doing something wrong in generally:

root@colibri-imx7-emmc:~# iwconfig
eth0      no wireless extensions.

lo        no wireless extensions.

can0      no wireless extensions.

Is there some missing that I cant see the LM816 in iwconfig list ?

Could you provide the complete bootlog and the output of lsmod?
