Usage

Example

Note: 
If there are multiple phys, i.e there are several instances of cfg80211 being used by different modules, then to determine 
the correct phy, run the following commands: 
$ cat /sys/class/ieee80211/ 
This will give a list of all the phy’s that are currently active. 
$ cat /sys/class/ieee80211/phyX/macaddress 
where 'X' is the number of the phys which are obtained from the previous command. The redpine module MAC address 
(xx:xx:xx:xx:xx:xx) has to be used in the field 'macaddress'. 
Generic iw commands listed below are also supported. Please refer to the man page of the utility for further information 
on their usage. 
$ iw phy <phyname> info 
$ iw dev <devname> del 
$ iw reg get 
$ iw reg set <ISO/IEC 3166-1 alpha2> 
$ iw dev <devname> scan dump [-u] 
$ iw phy <phyname> set name <new name> 
The commands that are supported only in the Access Point mode are as follows: 
$ iw dev <devname> set channel <channel> [HT20|HT40+|HT40-] 
$ iw dev <devname> set freq <freq> [HT20|HT40+|HT40-] 
$ iw dev <devname> station del <MAC address> 
$ iw dev <devname> station get <MAC address> 
Limitation: 
•  In STA alone mode, after connection iw reg set command is not expected. If this command is given then whatever 
country code is given in command will be applicable. In this case it may possible that STA may disconnect from 
connected AP. e.g. STA is connected to AP in JP (Japan region) on channel 14. If user is giving command iw reg set US 
then channels will be limited to 1-11 and STA will disconnect from AP and will be looking for AP in those channels only 
by running scan.
