694 +=== Step 2. Add gateways and devices to the multicast group ===
695 +
696 +
697 +Select a gateway on the "**Gateways**" screen, click "**selected gateways"**, and click "**Add to multicast-group**" to add the gateway to the corresponding multicast group, for example, **multicast_test01_au915**.

746 +
747 +=== Result ===

749 +Connecting to the SN50v3-LB using the serial USB-TTL port can check that two SN50v3-LBs are receiving Downlink at the same time
