Hello,
In IN865, only three default frequency is mentioned: 865.0625, 865.4025, and 865.985 MHz.
Could I add another frequency channels?
If Yes, Could you suggest with Frequencies should I use.
I want to use all 8 channel of gateway sx1303.
Thank You
For LoRaWAN pre-certification tool (LCTT) we use the below global_conf.json file.
Other frequencies could be used if following rules are applied:
