You are looking for <a href="https://www.bluetooth.com/what-is-bluetooth-technology/bluetooth-technology-basics/br-edr">Basic Rate/Enhanced Data Rate (BR/EDR)</a>, while the software stack we provide for the nRF5 series is for <a href="https://www.bluetooth.com/what-is-bluetooth-technology/bluetooth-technology-basics/low-energy">Low Energy (LE)</a>.</p> <p>If you need the Bluetooth BR/EDR stack, I am afraid you are on your own. We do not provide an implementation of this stack. If you have to use that stack, you will either have to find someone that has already made this stack for the nRF51, or you will have to make it on your own.</p> <p>The <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf51.v1.0.0%2Fsoftdevices.html&amp;cp=2_7">nRF51 SoftDevices</a> implements the Bluetooth Low Energy (BLE) stack. It is a precompiled and linked binary library for the nRF51, and it has an API that covers the roles, modes and procedures for BLE.</p> <p>Regards, Terje</p><div style="clear:both;"></div>
