In the data sheet of the NRF51 and 52 there is mention that sensitivity of NRF51 is -96 dBm and NRF52 -98.
But I read some where that when RSSI is -90 then that signal is unusable so what does the above mentioned value of sensitivities means ?
Does it mean that NRF51 and 52 can detect signal of -96 and -98 ?
Can you explain me more about this ?
