In the past I have setup my Laird Gateway using the old V2 console, but I am now trying on the V3 console but cannot seem to figure out how to do it… is there up to date documentation somewhere to show the process.
I am not sure what mode to use, “TTN Forwarder” maybe? and if so what the “Gateway Key” is.
The gateway is no longer registered in the V2 console, and has had a factory reset.
That is an obsolete protocol no longer supported on TTN (CE) (also known as V3). If you want to keep the current firmware use the Semtech/UDP protocol forwarder. Better, upgrade the firmware to the newest version and choose BasicStation. A quick search of the forum should find the topics dealing with setting up BasicStation on a Laird gateway. Like this message.
It can’t be as option 3 has been dropped from firmware builds some time ago. You need to upgrade to be able to use BasicStation.
If you don’t want to upgrade (upgrading can cause a factory reset in some cases) go for option 1, use eu1.cloud.thethings.network (or nam1 or au1) as destination server with port 1700. Do not set secure connections to true in the TTN console for that gateway.
