Installed the RAK gateway with the newest image and edited the global_conf.json in two ways:
a) changed the address to: eu1.cloud.thethings.network
b) exchanged the whole .json file with the one generated by v3.
Both didn’t show me a successful connection. What is the recommended way? I guess b) - taking the one of v3.
The service is running fine:
The EUI was correctly inserted in the local_config.json during installation.
It’s not a given that you actually need to do anything other than change the server address in the config file.
Whatever you do do not de-register your gateway in V2; leave that so that you can come back to it, and create a new registration. Only the version you actually point the gateway at will be active.
However, if your setup is an older one, it may be that you have an early version of the packet forwarder software without a jit queue, in which case you probably want to update. If in your packet forwarder sources you don’t have a jitqueue.c or messages about jit in the logs, then that might be the case.
If updating, I’d strongly suggest checkout out the code directly from Semtech rather than using a RAK or even TTN version of it; especially as the RAK831 doesn’t have the slow SPI of some later RAK products and so should not need any adjustment.
You may also want to do the install on a new SD card so that you can set the existing working one aside to come back to if you need.
