May I change the bit rate of the comuniucation dinamicaly ? For examples I see that with a 2Mb/s comunication is not so good ( The Master can&#39;t reach the Slave )The Masteren-USTelligent Community 13Wed, 05 Oct 2022 12:54:25 GMThttps://devzone.nordicsemi.com/thread/389419?ContentTypeID=1Wed, 05 Oct 2022 12:54:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3cc9ba24-4e85-456f-8a38-ae42ff5986a9Einar Thorsrud<p>Hi&nbsp;Novello,</p> <p>Which SDK are you using? If using the nRF Connect SDK, you can look at <a href="https://devzone.nordicsemi.com/f/nordic-q-a/85371/bluetooth-long-range-coded-phy-on-nrf52811-using-nrf-connect-sdk---provided-examples-use-too-much-sram/356074">this post</a>. If you are using the nRF5 SDK you can call&nbsp;sd_ble_gap_phy_update() with the rx and tx PHYs set to&nbsp;BLE_GAP_PHY_CODED. With&nbsp;extended advertising you can also establish connections on coded phy (see <a href="https://devzone.nordicsemi.com/f/nordic-q-a/56971/coded-phy-using-the-ble-advertising-module---invalid-params/238621">this post</a>).</p> [quote user=""]<p>There is in ble a parameter that show me quality of the link ? (QoS)?&nbsp;</p> <p></p>[/quote] <p>Not with the nRF5 SDK, but if you are using the nRF Connect SDK you can get information about that from the Bluetooth stack. This is used by the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.1.0/nrf/applications/nrf_desktop/doc/qos.html">Quality of Service module</a>.</p><div style="clear:both;"></div>
