https://devzone.nordicsemi.com/f/nordic-q-a/35874/set-tx-power-based-on-scanned-rssiHey, I would love some guidance on this: 1. I have one NRF52840 advertising constantly at 8dbm, this device is connected to power so it&#39;s hard coded to the maximum transfer power. 2. I have another battery powered NRF52840 that will occasionallyen-USTelligent Community 13Thu, 28 Jun 2018 08:37:37 GMThttps://devzone.nordicsemi.com/thread/138030?ContentTypeID=1Thu, 28 Jun 2018 08:37:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:515e4b89-b760-4a2d-a599-6c2dd7e86452Susheel Nuguru<p>If I am not reading this wrong, you are setting the tx_power of the scanner which is inversely proportional to the incoming signal strength of the ADV packet? I do not think that there is any complex math needed for this, and the inverse relation holds good. I guess what you are looking for is the numbers to map the incoming RSSI to scanner tx_power. There is no correct answer for this, since this is you as a designer who decides this as to how reliable transmission you need from the scanner and if the system could still survive if the advertiser missed to get response from the scanner.</p><div style="clear:both;"></div>
