Hi all

1. • Is it mandatory to run MQTT broker for chirpstack?
2. • i am using WM1302 LoRaWAN Gateway integrating with Raspberrypi . So should i install chirpstack in my Pi or can i install the same in my PC
3. • UDP packet forwarder will be running in my Pi while network server library and other functionalities will be in pc.is this how it works

Yes, all communication between gateway ↔ chirpstack goes through the broker.

If you plan on having multiple gateways you should download Chirpstack (including MQTT broker) on a separate server (your PC) and do the Chirpstack OS base install on your Pi. If this is your only gateway you could get away with doing the Chirpstack OS full install on your Pi, which includes the MQTT broker and Chirpstack.

This is a typical setup, although if you are using Chirpstack Gateway OS on your Pi you can use the MQTT forwarder rather then UDP forwarder, that way you can skip the gateway bridge and post directly to the MQTT broker.

You can look at the architecture here: Architecture - ChirpStack open-source LoRaWAN® Network Server documentation
