667 +=== Step 1. Create the multicast group ===
668 +
669 +
670 +Create the multicast group on the corresponding **Application~-~->multicast groups~-~->Add multicast-group** interface, For example, multicast_test01_au915

700 +
701 +
702 +=== Step 2. Add gateways and devices to the multicast group ===
703 +
704 +
705 +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**.
706 +
707 +[[image:image-20240923144335-6.png||height="619" width="1209"]]
708 +
709 +[[image:image-20240923144418-7.png||height="572" width="1206"]]
710 +
711 +
712 +On the **Application->Devices** interface, select two SN50v3-LB nodes registered with multicast support, and then click "**Selected devices**". and click "**Add to multicast-group**" to add the node to the corresponding multicast group
713 +
714 +[[image:image-20240923144749-9.png||height="623" width="1211"]]
715 +
716 +
717 +Access the multicast group to check whether two SN50V3-LBs and gateways are added successfully

720 +
721 +
722 +=== Step 3. Use the API for multicast Downlink ===
723 +
724 +
725 +To use API Downlink, user first need to generate an API key
726 +
727 +[[image:image-20240923145624-18.png||height="429" width="1211"]]

730 +
731 +
732 +For example:**[[https:~~/~~/www.chirpstack.io/docs/chirpstack/api/index.html>>url:https://www.chirpstack.io/docs/chirpstack/api/index.html]]**

735 +
736 +
737 +Users can access the Linux console of the gateway via SSH, and then use the curl command to multicast Downlink
738 +
739 +The format is as follows:
740 +
741 +(% class="box infomessage" %)
656 656  (((
743 +curl -X POST 'http:~/~/**Chirpstack_Server_Address**:8090/api/multicast-groups/**Multicast_Groups_ID**/queue' -H "Content-Type: application/json" -H "Authorization: Bearer **eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJhdWQiOiJjaGlycHN0YWNrIiwiaXNzIjoiY2hpcnBzdGFjayIsInN1YiI6IjM3YmRiNzBjLTNjODgtNDFjMi04YmQ2LTgyMDI4ZjdkNzY3NyIsInR5cCI6ImtleSJ9.p1xvRP1PAdwLnLAJn9w6ef612KM8oPZSa_2v4UYPV0w**" -d '{

746 + "fCnt": 0,
747 + "fPort": 123
748 + }
749 +}'
750 +)))
751 +
752 +In the command,eyJ........._2v4UYPV0w is the API key, which can be obtained from the Chirpstack server and the data format is base64,
753 +
754 +
755 +=== Result ===
756 +
757 +Connecting to the SN50v3-LB using the serial USB-TTL port can check that two SN50v3-LBs are receiving Downlink at the same time
