STM32WL55 as single chip 4-fsk transceiver

[ltoso.1]

Hi,

I'd like to understand how I can setup the semtech transceiver to work with 4-FSK modulation.

I configured a project in cube mx but I have doubts on the bandwidth and datarate parameters.I know that my datarate is 9600 bps, then bandwidth and coderate are not cleear for me.

Also, I'd like to use as middleware as possibile in this moment to have a clear understanding of what I am doing.

Also, in our project we have a system relying on some other configurations, like the usage of whiteneing algorythms with pseud-random generators and I suspect the Semtech chip is able to handle it, but it is no clear how.

Any hint or example to inspect?

Hello @Akito Ito​ and welcome to the Community 🙂

It is possible to define the bandwidth and parameters depending on the chosen modulation.

Please review this application note AN5406 that will guide you through all the steps required.
