This is an IoT operating system for the Raspberry Pi which supports interfaces such as the Waveshare LoRaWAN Gateway Hat.
BalenaEtcher is recommended to be used from Windows, else use `dd' in Linux.
A Pi with built-in WiFi will have an access point enabled and this AP will use the IPv4 address range 192.168.0.0/24
If this IP address range conflicts with the local LAN, login to via WiFI and change the network using the web interface and afterward attach an ethernet lead.
The O/S will assign itself a LAN address via DHCP. If you know the MAC address you can use that in advance to setup a fixed IP address.
Ensure that ignore interface is set for DHCP on the LAN. There should be no harm disabling dnsmasq authoritative DHCP for the LAN as well.
Under ChirpStack enable concentratord, in my case I enabled SX1302/SX1303 and then selected the Waveshare device on the SX1302/SX1303 tab.
Now enable MQTT forwarding and the gateway is up and running and the ChirpStack server application can now be configured.
