Uplink Data

When adding an MQTT topic for Uplink Data type or an HTTP URL for Uplink Data type, the gateway forwards the data from LoRaWAN® end devices. To receive notifications from a specific end device, add the wildcard $devEUI to the MQTT topic, then replace it with the device EUI when subscribing to this topic.
