PYNQ+Ultra96-V2 and Wifi???

buffteethr

Has anyone here run into an issue with the PYNQ v2.5 image for the Ultra96-V2 and WIfi? The wlan0 does not show up with the ifconfig command. I did some digging and noticed that there is NO wpa_supplicant.conf file is missing.

    Thanks that worked. My Wifi is up and running. Now I cant ping out. Weird. It is not and issue as I have my usb WEBCAM project running but I may need to update somethings using the internet.

    Thanks   That seems very useful because a python script can be written to handle setup in many situations. For instance a Home versus Work environment where the SSID/password change. Seems like a scan of signals could provide details on which to setup.

  • You don't need to configure Wifi through shell. Instead, configure it through python environment. The following is what I did and it works perfect.

     

    xilinx@pynq:~$ sudo python3

    [sudo] password for xilinx:

    Python 3.6.5 (default, Apr  1 2018, 05:46:30)

    [GCC 7.3.0] on linux

    Type "help", "copyright", "credits" or "license" for more information.

    >>> from pynq.lib import Wifi

    >>> port = Wifi()

    >>> port.connect("your_wifi_essid","your_wifi_password")

    ifdown: interface wlan0 not configured
