[AX210] How to capture 11ax trigger-based packets with AID

SOLGIL · ‎08-02-2023

Hi

As of now, I am able to capture 11ax SU packets (including full data packets) with the AX210 on Ubuntu 20.04 (kernel 5.15).

Going one step further, I am checking how to capture 11ax MU Trigger-based packets for the target Association ID. Could you let me know how to set the target AID to iwlmvm ?

I have read some post that the target AID can be set with the command below:
$ sudo echo <AID> <AP/BSS MAC> > /sys/kernel/debug/iwlwifi/*/iwlmvm/he_sniffer_params

Unfortunately, when I try this command on my Ubuntu 20.04 machine,

it showed "Permission denied" error message even though the command was excuted by root.

Did I miss something or do we have another way to give target AID information to iwlmvm ?
