FSK for nRF52832 possible?

[Yann]

Hi everyone!

I'm wondering, is FSK compatible with the nRF52832. I want to emit 2 differents frequencies that the receiver will be able to recognize. If yes, How to create it?

thank you

The nRF radios all use GFSK, similar to FSK. It will receive FSK as well. But note that you can't change the packet format must, it should have a certain structure, with preamble, adress etc. See more here. The datarate must be 1 or 2 Mbps.
