RSSI Measurement Mechanisms

Hi,

This is a follow-up question on RSSI measurements. I understand that it's generated from an ADC that measures voltage received from the antenna. My questions are...

  • Is the following equation from section 6.20.12.4 of the nRF52480's product documentation relevant in any way? If so is VAL_HARDWARE that generated by the ADC?

  • How does the Link Quality Indicator (LQI) factor into RSSI measurements? Is it the reason RSSI appears to saturate beyond a certain value (17dBm in my tests)?

  • Is there any further documentation on how RSSISAMPLE is generated?

I understand if any of this is proprietary information and can't be discussed; I'm trying to get as much information on RSSI measurements for a university project and any help would be much appreciated. Thanks.
