This project allows you to execute a device communication on your Astarte cluster.

Before you begin, ensure you have a running Astarte cluster either on your local machine or accessible remotely. To manually build an Astarte cluster, follow this guide.

Alternatively, you can set up an automated instance on Astarte Cloud here.

Follow these steps to get started with this project:

1. Clone the Repository

   Begin by cloning this repository to your local machine.

git clone https://github.com/astarte-platform/astarte-device-sdk-elixir.git

2. Install the Elixir and Erlang Version

   You can use ASDF to install these versions:

asdf install

3. Fetch Dependencies

   Fetch the project dependencies using the mix deps.get command.

mix deps.get

4. Compile the Project

   Compile the project using the mix compile command.

mix compile

5. Run the Project

   Run the project using the iex -S mix command.

iex -S mix

You can explore the tools inside by entering the IEx shell and typing h Astarte.Device.

Initialize a device instance

You can easily initialize a device by following the steps below:

Create a device option variable as follows. Use your parameters taken when you have created a device from Astarte Cloud or on astartectl:

device_options = [ pairing_url: "https://api.your-astarte-instance/pairing", realm: "realm_name", device_id: "device_id", credentials_secret: "device_secret" ignore_ssl_errors: false, interface_provider: "./path-to/interface.json" ]

To interact with your realm, you can either save the Device PID when starting the start_link function or retrieve it later using the get_pid function:

{:ok, pid} = Astarte.Device.start_link(device_options)

or

pid = Astarte.Device.get_pid("realm_name", "device_id")

To send data through your interface, use the set_property or send_datastream functions. These functions require four parameters: the device process PID, the interface name, the path, and the value you want to send. An optional fifth parameter, opts, is also accepted:

Astarte.Device.set_property(pid, interface_name, path, value)
Astarte.Device.send_datastream(pid, interface_name, path, value, opts \\ [])
