HTM01 - AU915 Sub-Band 1

#1

Helloo Guys,

In my HTM01, following the tutorial in …/home/lora/lorasdk I just found the global_conf_AU915_SB2. There is no global_conf_AU915 or global_conf_AU915_SB1.

The devices that I wanna connect to the HTM01 gateway are in AU915 SB1. Can you provide this file or give me the information that I need to change in the global_conf_AU915_SB2 file?

Thanks in advance.

Hello, I did by myself the file, and it works, at least in the first test. Can someone just check if is correct? I used the documentation from HELTEC (https://heltec-automation-docs.readthedocs.io/en/latest/general/sub_band_usage.html) as base.

I just dont get what radio_0 and readio_1 really means. I just made some calculation in order to achieve the desire frequencies for AU915 SB 1
