Connect to WiFi networks on Nerves platforms.
If available in Hex, the package can be installed as:
-
Add nerves_interim_wifi to your list of dependencies in
mix.exs
:def deps do [{:nerves_interim_wifi, "~> 0.1.0"}] end
-
Ensure nerves_interim_wifi is started before your application:
def application do [applications: [:nerves_interim_wifi]] end
-
Set the regulatory domain in your
config.exs
. This should be set to the ISO 3166-1 alpha-2 country code where the device is running. If your device ships to more than one country, seeNerves.InterimWifi.set_regulatory_domain\1
.config :nerves_interim_wifi, regulatory_domain: "US"
Setup your WiFi connection by running:
Nerves.InterimWiFi.setup "wlan0", ssid: "my_accesspoint_name", key_mgmt: :"WPA-PSK", psk: "secret"
If your WiFi network does not use a secret key, specify the key_mgmt
to be :NONE
.
Currently, wireless configuration passes almost unaltered to wpa_supplicant.ex, so see that
project for more configuration options.
Currently, only IPv4 is supported, and IP addresses can only be assigned via DHCP. The library is incredibly verbose in its logging to help debug issues on new platforms in prep for a first release. This will change. The library is mostly interim in its structure. Please consider submitting PRs and helping make this work reliably across embedded devices.
