Building a terminal for patient self-registration is relatively simple. Managing tens or hundreds of these devices in production is another matter. This is the story of how we used Elixir, Nerves, and NervesHub to build a custom hardware device, package its firmware, and manage deployments and upgrades. We will explore the Elixir programming language and the BEAM runtime, how Nerves elegantly packages an application and its runtime as firmware, and what NervesHub brings to the table in terms of device management and firmware deployment.
