Downlink CMi4130 supports configuration via downlink, i.e. sending commands to an end-device via the LoRaWAN network. Note that this feature should only be used sparingly due to bandwidth consideration. Communication via downlink is sent on port 2 and can only be made in a short window after an uplink transmission from module to server.
