Astronode GUI

The Astronode Graphical User Interface (GUI) is a Windows application helping you configure the Astronode DevKit. The GUI also allows you to send data and monitor events such as acknowledgement reception on the Astronode S.

It is compatible with Wi-Fi and Satellite board.

Download & Installation

See Tools & Libraries section for the GUI installer.



Launch the Astronode GUI application on your computer.

Select COM Port

Connecting the Astronode DevKit to your computer through a TTL cable should mount a COM Port on your computer. You need to select the right port.

Here is the process on Microsoft Windows 10:

  1. Open Device Manager.
  2. Click on View in the menu bar and select Show hidden devices.
  3. Locate Ports (COM & LPT) in the list.
  4. Check for the COM ports by expanding the list.

Set geolocation (optional)

  1. Enter the Latitude.
  2. Enter the Longitude.
  3. Set Add to messages to ON.
  4. Click on Set geolocation config.

Setup Wi-Fi network (only for Wi-Fi board)


Only 2.4 GHz Wi-Fi access points are supported.

  1. Enter the SSID of your Wi-Fi network.
  2. Enter the Password for your Wi-Fi network.
  3. Enter the Astrocast Token with Wi-Fi DevKit role (Learn how to Create an access token).
  4. Click on Set Wi-Fi config.

Enqueue a message

  1. Enter your message into Enter your message textbox. A message can be up to 160 bytes.
  2. Click on 📨 Queue message.

For a first trial, we recommand you to keep your payload short (like 10-30 bytes).

Get an ACK from the satellite

If the transmission is succesful, your DevKit will get an acknowledgement (ACK) from the satellite.

You will see the "Acked" circle on the Astronode GUI turn to green. 🟢
