https://devzone.nordicsemi.com/f/nordic-q-a/126047/ble-and-usb-contentionWhile testing BLE and USB individualy, they seem to work well. When there is simultaneous use, there appear frequent crashes/lock-ups in varius handlers. BLE used: ble_app_uart-periph, from SDK_3.2.0.

Have you done any debugging? What have you learned from that?</p> <p>Also, can you double check the SDK version, as nRF5 SDK 3.2. does not exist. (There should be a&nbsp;release_notes.txt file under&nbsp;documentation that tells you which SDK version it is).</p><div style="clear:both;"></div>
