I am setting up the “beacon_pkt_fwd” on the RAK831_915 gateway. The code below is the first portion of my global_conf.JSON saved in the beacon_pkt_fwd directory.
My first question is about the “freq”: value in both the radio_1, and radio_0 section.
I am in the US, so I will need to use the 915 frequency band. Should I set both the radio_0, and the radio_1 section to 915?
My second question is about the “rssi_offset”: value. What does this number do? Is this a value that I should change in order to troubleshoot the rssi I am getting on each transmission? Or is this a standard value that I should just leave alone?
Lastly, should I adjust any the “chan_multiSF_” ?
I am a bit uncertain about all the information in the global_conf.JSON, any help would be appreciated.
