Hi,
I have a simple problem (?), but I cannot find any answer in google and wireless.kerner.org.
I use 3.16.1 kernel/backport version with ath10k/QCA9880.
I want to handle freq/BW to test its performance.
When I change center frequency and BW by using iw command, linux reports “command failed: Device or resource busy (-16)” as follows.
$ modprobe ath10k_pci
$ iw wlan0 set channel 36 HT20
command failed: Device or resource busy (-16)
$ iw wlan0 set freq 5180 40 5190
command failed: Device or resource busy (-16)
$ iw wlan0 set freq 5180 80 5210
command failed: Device or resource busy (-16)
Curiously if anyone else has solution for this problem?
Thank you.
