Clarification on which Gateways receive SendDataToWirelessDevice downlink messages

0

Our AWS account supports multiple private LoRaWAN networks (multi tenant- for different customers).

When sending a downlink to a Class A Device using SendDataToWirelessDevice Device ID is provided. Which Gateway(s) is this message dispatched to? Is it sent only to the Device's "Last connected gateway", or?

I want to ensure downlinks destined for CustomerA do not broadcast to CustomerB's Gateways.

AWS IoT Core for LoRaWAN tracks which gateway a device is adjacent to, based on last known uplink RSSI. Downlink messages are sent to only that adjacent gateway.

    Is adjacent defined as: the gateway having recently seen traffic from the device and having the strongest RSSI to the device?

    Yes that's right.
