RAK7249 8 Channel Redundancy


I set up my RAK7249 16 channels with the same config/frequency for concentrator 1 & 2:

  • Concentrator 1 : 920.2, 920.4, 920.6, 920.8, 921, 921.4, 921.6, 921.8
  • Concentrator 2 : 920.2, 920.4, 920.6, 920.8, 921, 921.4, 921.6, 921.8

What happens during Tx, which concentrator will be used for TX? Does this disable the Rx of one concentrator when Tx on another concentrator?

Dear Andri,

If you need to set up the same channel, it is not necessary to turn on both channels at the same time, as you are using two 8-channel gateways!

Hi @xflash,
First of all, could you explain why are you trying to use both concentrators with the same chanal frequency?
You can refer to this document: https://downloads.rakwireless.com/LoRa/DIY-Gateway-RAK7249/Application-Notes/Packet_Forwarder_Customs%20_Spectrum_Setting_KR920.pdf
but keep in mind that it’s about KR920 settings.
