I live in Brasil and following the Frequencies Overview we are to use the AU915-928 Frequencies here. The gateways that we have and devices we make work fine with this plan.
The problem is that we are trying to buy a LoRaWan device from China and they insist on the RX2 Frequency. But the frequency plan we use here is not specified nor using the RX2 window.
Any advice on how to resolve this problem? Should I specify a dummy RX2 window? Will this work?
