For the time being I’m setting a “custom LoRaWAN Service Provider” and setting my Chirpstack Server network URL under server address. Here you should paste your URL. As a reminder, you should have the chirpstack gateway bridge up and running in your server too if you try this approach.
The other option is to set “localhost” as your server address and install the gateway bridge in the gateway itself. I prefer this option since this way you can offload one process from the server and at the same time strengthen the reliability (because now the packets will be sent over TCP rather than UDP).
The problem is I tried installing the gateway bridge in my LPS8 but couldn’t get it to work. I opened an issue thinking the error was due to some minor incompatibility between the LG308 and LPS8 gateways but @paolofrs told me he could make it work. I will now try again and tell you if I get lucky this time.
