LoRa – Device Re-activation Call Flow (Rejoin Procedure)

LoRa Technology supports the handling and configuration of rejoin-requests for LoRa End Devices. Using a rejoin-request, a device is able to request the network-server to re-activate, without being ‘disconnected’ until receiving the activation. In other words, when it doesn’t receive a new activation, the device will continue to use the old security context. With the…
