Deployment

Device Registration and Configuration

The relay supports registration of up to 10 end devices. Registration is performed via a dedicated
“setup device” equipped with LoRa capabilities and acting as a temporary gateway. This setup device
manages a registry of relays, their associated end devices, and the selected exploration mode—periodic
or non-periodic.

During the registration process, the relay queries the setup device to obtain configuration details.
In response, the setup device provides the list of end device addresses, their corresponding AppSKey
and NwkSKey, and, if applicable, the transmission period for periodic operation. This process enables
the relay to identify which devices to listen to and ensures secure and efficient operation in the field.
