RAK831 which global_conf.json?
I am setting up a RAK831 Raspi LoRaWAN gateway. I have used an excellent tutorial. The gateway is now set up and connected to TTN.
However, as this gateway will Operate in AU915 region I need to adjust the global_conf.json file to the AU915 frequencies.
-however which global_conf.json do I change? This file appears in multiple locations.
-what does 'adjust' actually mean? Do I have to 'replace' the global_conf.json with the AU-global_conf.json ?
