pinging and compacting the Q just in case the experts have an idea on this..
Is it possible to control spectral_scan_ctl whilst in AP mode? my result: root@OpenWrt:~# echo disable > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl ash: write error: No such device or change channel whilst in Monitor mode? my result: root@OpenWrt:~# iw dev wlan0 set channel 112 command failed: Device or resource busy (-16) Thanks Will. ________________________________ From: Will Kerr <willjk...@yahoo.co.uk> To: "ath10k@lists.infradead.org" <ath10k@lists.infradead.org> Sent: Friday, 24 February 2017, 6:49 Subject: ath10k - spectral scan - and - channel change Hello, I searched the mail archives but couldn't find a clue to my question so here it is: Im interested in performing a spectral scan of as much of the spectrum as possible, and quickly. this means scanning a channel for some time, changing channels, and repeating. Background: when configuring an ath9k radio to Monitor mode, it is possible to do 2 things: 1) change wifi channel via command line, e.g. iw dev wlan1 set channel 3. This does it seemingly quickly, without taking down the interface (good) 2) control the debugfs files like /sys/kernel/debug/ieee80211/phy1/ath9k/spectral_scan_ctl (good) The problem is: ath10k, in Monitor mode, I am only able to change channels - 1) iw dev wlan0 set channel 104, but not access the debugfs files 2) (which is essential to control and obtain the spectral scan result) the error I get is: root@OpenWrt:~# echo disable > /sys/kernel/debug/ieee80211/phy0/ath10k/spectral_scan_ctl ash: write error: No such device ath10k, in AP mode, The opposite occurs - I am only able to access debugfs files 2) , but not change channel 1), which is annoying because I cant then scan the entire possible range. the error I get is one of: root@OpenWrt:~# iw dev wlan0 set channel 112 command failed: Device or resource busy (-16) or root@OpenWrt:~# iw dev wlan0 set channel 104 command failed: Invalid argument (-22) Is there anything I can do to get both working? Thanks. Will _______________________________________________ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
