Add Device to Console

To start, you'll need to add your device to Console. You should have been provided with a DevEUI, AppEUI, and AppKey from the seller of the device. Follow our quickstart for instructions on how to add a new device to Console.

Device Configuration

The following device configuration changes are required for the device to function properly on the Helium Network. Although the Adeunis IoT Configurator application makes the device configuration much easier, it does not allow you to change all the required settings, so we must use a serial utility. We are using Realterm for our serial utility, but any will work, just be sure to use the correct serial settings and send the commands in the correct format.
