Hi everyone,
I am trying to get link quality information from an 802.11ac interface
and it looks like the only way is to use "iw wlan2 scan". I don't like
this solution as it scans all channels and takes a while.
If I try "cat /proc/net/wireless" (this would be my preferred option)
the output is empty and I am not able to get this information with any
other tool. Below is the output for some commands I tried.
I am using kernel 4.2 with ath10k and Candela firmware 10.1 on a
Qualcomm Atheros QCA988x
Any ideas on how can I get the link quality information?
Thanks,
Inaki

Did you try: iw dev wlan0 station dump If you want tx rate reporting, you need to run my driver patches as well as my firmware, but rx-rate should be reported with stock driver (and stock firmware, for that matter)...

Signal quality is probably the most similar value, but tx and rx bitrates give you the best idea of how RF is performing in my opinion. Those rates are only accurate when sending at least modest amounts of packets though.

It is working in CT firmware (when using my patched ath10k driver to support the feature), and I have no way to get changes into upstream QCA firmware.
