Get Multicast uplink/downlink frames

Question

Hello,

We've successfully configured the multicast, created a script that do all the provisionning that we'll share once it's ready (because the FUOTA UI is only tied to FUOTA, not simple multicast). Everything works fine, also from a FUOTA point of view. Using https://github.com/Lora-net/SWL2001/tree/master.

We are testing the multicast capability outside of a FUOTA context, for exemple to mass-configure device. We need to double check the frames exchanged in the multicast session, is there a way to check the uplink/downlink frames for the multicast group ?

For information the frames are visible in the gateway but they are encrypted I believe

We are using Chirpstack on-premise so we are open to deep log extraction from the server itself if needed.

Thanks

Please note that there are two parts:

The multicast session-setup
The actual multicast downlinks

It is not fully clear if you are interested in the first part, or the second, or both? The multicast session-setup commands are sent as unicast to the LoRaWAN end-devices, so you should be able to see these in the LoRaWAN frames tab for each device.

Sorry if my message was unclear. I'm aware that the setup is sent as unicast, we are monitoring it closely.

I'm talking about the multicast downlinks themselves. And potentially uplink.
