Supported USB WiFi devices

The base image includes drivers and firmware for Ralink RT53xx (rt2800usb driver) and RealTek RTL8712U (r8712u driver) devices.

We are still working out which subset of all possible WiFi dongles to support in our images. At some point, we may have the option to support all dongles and selectively install modules at packaging time, but until then, these drivers and their associated firmware blobs add significantly to Nerves release images.

If you are unsure what driver your WiFi dongle requires, run Raspbian and configure WiFi for your device. At a shell prompt, run lsmod to see which drivers are loaded. Running dmesg may also give a clue. When using dmesg, reinsert the USB dongle to generate new log messages if you don't see them.

Installation

If available in Hex, the package can be installed as:

  1. Add nerves_system_rpi2 to your list of dependencies in mix.exs:

    def deps do
      [{:nerves_system_rpi2, "~> 0.10.0"}]
    end
    
  2. Ensure nerves_system_rpi2 is started before your application:

    def application do
      [applications: [:nerves_system_rpi2]]
    end
