I am trying to find the specific code to see how the demodulation and mixing was done for the demo code. Actually I need to be able to change the demodulation and mixing part of the code so that I can use it for my project. I have found the demo code for the RX part, but don't understand where to work to see the how demodulation and the mixing was done here.
At least for the SI4463, the demodulation is handled by the chip and is set by the WDS to ether on / off keying, or FSK / GFSK...
can you tell us more about what you are trying to accomplish?
Indeed, it would be good to know more about what kind of signals you would like to see exactly.
Thank you for the feedback.
