https://devzone.nordicsemi.com/f/nordic-q-a/42076/changing-bluetooth-range-of-nrf52840Hi, I have an application wherein I need to scan for beacons within a desired range(10m, 20m) using nrf52840. I know of adjusting the transmit power using gap_ble_tx_power_set(int8 tx_power) function in the library which can be used for beacons. en-USTelligent Community 13Wed, 02 Jan 2019 15:11:36 GMThttps://devzone.nordicsemi.com/thread/163499?ContentTypeID=1Wed, 02 Jan 2019 15:11:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5e16b991-27a0-4822-a3dd-163ac6b396e7awneil[quote userid="74132" url="~/f/nordic-q-a/42076/changing-bluetooth-range-of-nrf52840"]Will above setting work in case of a scanner?[/quote] <p>What do you mean by &quot;work&quot; ?</p> <p>It will work in that it will adjust the scanner&#39;s transmit power.</p> <p>But that won&#39;t be any help in determining how far away the beacons are!</p> <p>Do a search of this forum for the many, many previous threads on trying to determine distance using BLE ...</p><div style="clear:both;"></div>
