To read User Description descriptor you would need to getDescriptor(UUID) with UUID = 0000<strong>2901</strong>-0000-1000-8000-00805f9b34fb</p> <p>You can refer to how we get the CCCD (0000<strong>2902</strong>-0000-1000-8000-00805f9b34fb) in our examples, for example in enableTXNotification() function in nRFUART app example.</p><div style="clear:both;"></div>
