https://devzone.nordicsemi.com/f/nordic-q-a/16121/useful-rssi-range-in-nrf51822Dear nordic. We are developing nRF51822 with S120 as central. When advertising from Peripheral, RSSI value is changed it&#39;s position. Measured RSSI range is -60 dBM to -110 dBM and in some cases, cann&#39;t receive advertising. &quot;RSSI accuracy&quot; Validen-USTelligent Community 13Thu, 01 Sep 2016 13:01:16 GMThttps://devzone.nordicsemi.com/thread/61467?ContentTypeID=1Thu, 01 Sep 2016 13:01:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b3d2ea41-d9f8-4318-b50c-858fe337254eSusheel Nuguru<p>I think the specification took into consideration extreme test conditions and also to generalize for both 1Mbps and 2Mbps it gave a safe number.
