https://devzone.nordicsemi.com/f/nordic-q-a/30912/i-am-not-able-to-get-stable-rssi-value-with-nrf51822Hi, I am using nrf51822 with SDK 12.2.0. As of now, we are using RL-51822-A1 for beacon as well as scanner. But, we are not getting stable pattern for RSSI at 2m, 4m and 6m range. Herewith i attached images which represent the graphical pattern.

There is a &nbsp;chip to chip production variance + variance over input power + margins. You will also always have slightly different performance across the different BLE channels.&nbsp;The environment in which you measure this would also affect the result as you will have reflections that can vary over frequency.</p> <p>If you want to use the RSSI to something useful, I would recommend doing some filtering on the raw RSSI measurements. E.g. use a Low Pass Filter, these are often used to reduce the deviation of RSSI measurements.</p><div style="clear:both;"></div>
