How to transmit LoRaWAN packets on single frequency in STM32WL?

Estej.1 · ‎2021-11-27

Hi

I'm designing a LoRaWAN end node based on RAK3172 and LoRaWAN_End_Node example. The frequency band is 868 MHz but i want to transmit on single frequency for example 868500000 Hz.

I read the example but I don't know how to send packets only on single frequency. How can I do that?

Thanks.

Welcome, @Estej.1, to the community!

LoRa not only uses a specific, given frequency for transmission, but a spread spectrum method. Maybe it would be helpful to have a look at the information from e.g. Wikipedia: LoRa/LoRaWAN or Chirp Spread Spectrum.

Are you sure you want LoRaWAN and not LoRaP2P ?

Perhaps grep the source for "_REGION" and sources under Middleware/LoRaWAN/Mac/Region
