improve the sweep_dump rate #10

Open yujianyuanhaha opened 3 years ago

yujianyuanhaha commented 3 years ago

the current beam SNR collection is around 3 sample per second with the AP-Client range 0 to 8 meter, it is true the rate could be as high as 10 sample, but most of the time it is not sufficient, especially when we do need to explore the application of the moving robot localization or consecutive human moving sensing.

Recently I found that changing the beacon length value /ect/hostapd_wlan2.conf can affect the sample rate. However during several trials I found other customized values beside default 100 will result in unstable 60G connect, which theiperf3 link easily broke down soon in a few minutes.

Is there any suggestion can fix this

hello!I am also a postgraduate who is using this platform.I wonder that if you have accessed RSSvalues .What i know is that I can access SNR in /sys/kernel/debug/ieee80211/phy2/wil6210/sweep_dump.So how can I access RSS? Is there any suggestion can fix this?

@tgs-cpu please go through the tutorial, the repository itself has provide the tool for get RSSI and beam SNR.

tgs-cpu commented 3 years ago

can you be more specific?please.I have been confused for a few days.Thank you.Or we can talk through wechat:15284281868.

Excuse me, have you solved the sampling problem with the talons devices? I have no idea about increasing the sample rate. if you had already fixed it, could you kindly share your method? thanks.

Best, Q.

@moie707 sadly but no, I shift to radar sensor later.

common-wears commented 3 years ago

@yujianyuanhaha well, thank you all the same. I also work on radar sensors, which seem much more accessible to obtain data than the COTS devices.
