error rate rssi

Dear Dialog,

I would like to know the bit error dependancy on the receiver's rssi. Our system is using DA14580
外围和中心。对decide the maximum distance for our actual application,
we need to set the criteria on rssi value based on the wireless layer's error rate dependacy.

So, I'm appreciated very much if Dialog can provide any experimental data relating to this purpose.

Best Regards,
yukio
