Hello,
We wanted to announce the public release of a small and useful tool used internally, the LoRaWAN Multicast Configurator.
This tool allow you switch your 1.0.4 LoRaWAN sensor into multicast using official LoRaWAN packages (TS005-2.0.0), so you can try out multicast class C directly on your production firmware.
Why it has been developed: Because Chirpstack UI focus only on FUOTA, not on general multicast usage.
