Chirpstack Multicast Setup

Hi Dears,

I am trying to create a Multicast group. First, I tried with Chirpstack, which has all the settings set. The devices send just join requests. I may have created them wrong. However, I can get data from devices or send downlinks to devices when I use the gateway network server, which is the Rak Indoor Gateway server.

Given the current situation, I’m wondering if there are specific adjustments I should have made in the Chirpstack settings parameters to enable device joining. Could you provide guidance on the correct configuration for our devices to join the Multicast group?

Our devices are working with Class-C.
