Are you sure the example is using coded_phy? Can you post the debug log outputs?</p> <p>Can you try to test <a href="https://github.com/jimmywong2003/nrf52-ble5-long-range-demo">this</a> long range example with SDK 15.3.0 and see if it works?</p> <p>BR,</p> <p>Marjeris</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/210841?ContentTypeID=1Fri, 20 Sep 2019 07:39:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3f89cedb-fc13-4dd7-8230-1c216b484ca6hana<p>I am developing with our board based on SDK 15.3.0 and SD 6.1.1. But the distance is really similar with compiled&nbsp;binary&nbsp;by using&nbsp;<span>ble_app_att_mtu_throughput_test.zip on SDK 15.3.0 with Soft Device 6.1.1. Did you&nbsp;check the distance on your side with ble_app_att_mtu_throughput_test.zip&nbsp;based</span><span> on SDK 15.3.0 version and SD 6.1.1? If I miss big issue for ble_app_att_mtu_throughput_test.zip example migration, please let me know.</span></p><div style="clear:both;"></div>
