The LoRa setting page is the configure page for LoRa transmission parameters about
Radio frequency, Bandwidth, Spreading Factor, Code Rate and the Transmit power. Click
“Read” to down load previous setting, and “Writing” to keep new settings into LM100
and LC100.
This setting page is not available for LR140. Since, LR140 follows LoRaWAN standard
