Hello.
I am testing Generic FSK example on MKW41Z EVM.
The datasheet shows that sensitivity can be improved at 250Kbps data rates.

So I changed radio configuration parameters like a below because for sensitivity improvement but wireless communication does not work.
Default:
static GENFSK_radio_config_t radioConfig =
{
.radioMode = gGenfskGfskBt0p5h0p5,
.dataRate = gGenfskDR1Mbps
};
My setting:
static GENFSK_radio_config_t radioConfig =
{
.radioMode = gGenfskGfskBt0p5h0p5,
.dataRate = gGenfskDR250Kbps
};
What else do I need to change to use 250Kbps?
Thank you.
