RAK7249/58
Standard Mode:
You can start by importing a region via the drop down menu (EU868 is the default one). You
will get the defaults channels for the chosen frequency band and the option to add additional
ones. Simply enter the frequency in the text box (in MHz) and click the "Add" button. You
can add as many channels as you need as long as they fall in the Regional band.
Additionally there is a field for adding the Standard LoRa Channel and FSK channel (you
need also choose the SF, Bandwidth and data rate of each of the aforementioned).

Advanced Mode:
Because of the presence of double SX1257s, you need to configure the two radios
separately. You have eight Multi Spreading Factor Channels, The LoRa Standard Channel
and the FSK Channel. The sliders can enable or disable those, so you can choose to have
any number of them active. Additionally you can choose which radio to use for a given,
channel as long as you do not assign more than five channels per radio. In order to set the
desired channel to a given frequency you need to input an offset value in the If field. Thus,
the channel frequency will be the central frequency (Radio 0 Freq or Radio 1 Freq
parameter) summed with the offset value (in Hz).
Additionally for the LoRa Standard and FSK channels, you are also required to select the
Bandwidth and Data Rate.
