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.
