That will often lead to an APP_UART_COMMUNICATION_ERROR event as noise is induced on the input. You can try to comment this line to confirm:</p> <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; case APP_UART_COMMUNICATION_ERROR:<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <strong>//APP_ERROR_HANDLER(p_event-&gt;data.error_communication); &lt;-- Ignore communications error</strong><br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; break;</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
