Sorry but only CN490 no CN470 LoRaWAN Region Configuration?

I am from china and see nothing about CN470 frequency band setting here.

After checking this tutorial, I find something about CN490 and it is not complete.

What is the relationship between CN490 and CN470? And should I complete the missing files about CN490?

To be honest, it is hard to add a region even using the copied US915 files…

Sorry, @wong-hao, it is kind of difficult to add regions, as you’ve found. What hardware are you using? I can perhaps guide you (and do some testing here with a network simulator).
