STM32WLE5 frequency deviation for FSK modulation

DTomi.1

Greetings,

what is the recommended frequency deviation parameter for the FSK modulation with 250 kbps bitrate?

Or rather what is the dependency of RX sensitivity in relation to the FSK_FDEV parameter?

I can see that the limitation is to have the modulation index > 0.5, so in this case that would mean that FSK_FDEV > 62.5 kHz and also the limitation is on BW, so FSK_FDEV < 125 kHz.

In that range, what FSK_FDEV will give me the best RX sensitivity?

Best regards,

Domagoj
