how to run wi-fi usb dongle as wlan0.client

[dragniko]

Ethernet works fine, but I have hard time understanding steps like where to put wpa_supplicant.conf file and what needs to be in it such that wi-fi behave like client not the server. Right now I have in /boot/wpa_supplicant.conf the following

# Red Pitaya WiFi configuration file
ctrl_interface=/var/run/wpa_supplicant
network={
        ssid="myssid"
#       proto=RSN
        key_mgmt=WPA-PSK
#       pairwise=CCMP TKIP
#       group=CCMP TKIP
        psk="myssidpassword"
}

This setting works fine on the latest RP OS image found at http://redpitaya.com/quick-start/ but there /etc/network/interfaces file looks like

# interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:

# source-directory /etc/network/interfaces.d
source interfaces.d/eth0
source interfaces.d/wlan0

and interfaces.d/wlan0 is a link to wlan0.ap, which looks like

##############################################
# wlan0: Wireless USB adapter AP config      #
##############################################

allow-hotplug wlan0
iface wlan0 inet static
  address 192.168.128.1
  netmask 255.255.255.0
  post-up service hostapd restart
  post-up service isc-dhcp-server restart
  post-up iptables-restore < /etc/iptables.ipv4.nat
  pre-down iptables-restore < /etc/iptables.ipv4.nonat
  pre-down service isc-dhcp-server stop
  pre-down service hostapd stop

However, there is also a wlan0.client file that looks like

##############################################
# wlan0: Wireless USB adapter client config  #
##############################################

allow-hotplug wlan0
iface wlan0 inet dhcp
    pre-up service hostapd stop
    pre-up service isc-dhcp-server stop
    pre-up wpa_supplicant -B -D wext -i wlan0 -c /boot/wpa_supplicant.conf
    post-down killall -q wpa_supplicant
    udhcpc_opts -t7 -T3

which looks for user's local configuration in /boot/wpa_supplicant.conf. Which scripts are used to create wlan0.client and to read it? Where do I tell that wlan0 is in client not the server mode? Thanks for your time and effort Dragan

Hi Dragan,

I'm afraid I don't know how to answer your questions. I'm not the author of the client Wi-Fi configuration for Red Pitaya.

I'd suggest to ask this question the Red Pitaya support or to copy this ticket to the Red Pitaya repository at https://github.com/RedPitaya/RedPitaya.

There are also some instructions at https://github.com/RedPitaya/RedPitaya/blob/master/NETWORKING.md but I don't know if they are up-to-date.

Best regards,

Pavel

you were correct, in the latest RP image wlan0 is the soft link to either wlan0.ap (access point mode) or wlan0.client (client mode). Personal preferences are read from /boot/wpa_supplicant.conf, so all works fine now.
