How to control the radio rangehttps://devzone.nordicsemi.com/f/nordic-q-a/79572/how-to-control-the-radio-rangeHi There, I am developing BLE Mesh applications based on Mesh 5.0, how to control the radio range? like 5 m, 10m, 15 m etc. Regards, Gaosheng Liuen-USTelligent Community 13Mon, 13 Sep 2021 14:32:34 GMTRE: How to control the radio rangehttps://devzone.nordicsemi.com/thread/329271?ContentTypeID=1Mon, 13 Sep 2021 14:32:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:612fe0bb-8799-44d2-9399-27d050dda30elgs<p>Thank you, Mttrinh!</p><div style="clear:both;"></div>RE: How to control the radio rangehttps://devzone.nordicsemi.com/thread/329259?ContentTypeID=1Mon, 13 Sep 2021 13:51:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:97b1f932-cb32-4620-b293-67d3479d2adaMttrinh<p>Hi,</p> <p>It is not possible to set the radio range to a specific number of meters. You can increase/decrease the range by changing the tx power. If you like to change the&nbsp;tx power during normal mesh activity or provisioning using ADV-bearer, you can use <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.meshsdk.v5.0.0/group__ADVERTISER.html#ga5018951ad5b1e191441f826b7b960189" rel="noopener noreferrer" target="_blank">advertiser_tx_power_set</a><span>().&nbsp;To change tx power when the device is getting provisioned using GATT-bearer, you would need to call&nbsp;sd_ble_gap_tx_power_set() after you call ble_stack_init().</span></p><div style="clear:both;"></div>
