Modulation proprietary protocol

[Elia_pell]

Dear all,

I managed to implement custom firmware using Nordic proprietary protocol (both 1 and 2 MBPS) on nNRF-52840-DK. I would like to know if some spread spectrum tecnique (as for example DS-SS) are used in lower layer, or only FSK modulation is used.

Thanks to all,

Elia

 It's GFSK only.
