This example shows how to connect your Nerves device to the network using WiFi. The directions below show how to use the Raspberry Pi 3 with its built in WiFi, but it will also work with a variety of popular USB WiFi dongles on other targets.

If you are using a Raspberry Pi 3, the WiFi hardware is already built-in. If you're using another board, you will need to connect a supported USB WiFi dongle.

1. Configure your WiFi settings by editing config/config.exs (note: ssid is case-sensitive`)

   # config/config.exs
   use Mix.Config
   
   config :blinkfi, :wlan0,
     ssid: "my_accesspoint_name",
     key_mgmt: :"WPA-PSK",
     psk: "secret"

2. Specify your target with the MIX_TARGET environment variable

3. Get dependencies with mix deps.get

4. Create firmware with mix firmware

5. Burn firmware to an SD card with mix firmware.burn

6. Connect a monitor to the HDMI port on the board

7. Insert the SD card into your target board and power it on

8. After it finishes booting (about 5 seconds), pressing the button will log events to the console on the HDMI monitor

export MIX_TARGET=rpi3
mix deps.get
mix firmware
mix firmware.burn
