Have you tried <a href="https://devzone.nordicsemi.com/question/60125/my-device-is-freezing-and-restarting/">debugging</a> to see if any error codes are returned from any functions?</li> <li>You should use the event handles to check which characteristics are written. I recommend that you have a look at the <code>on_write()</code> and <code>ble_*_on_ble_evt()</code> functions in the ble_services implemented in the SDK, for instance ble_hrs.c or ble_nus.c.</li> </ol> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
