https://devzone.nordicsemi.com/f/nordic-q-a/15124/printf-interrupted-sdk130Dear all, I&#39;m using SDk130 and the Software is based on the ble_app_uart_c example. Now I want to scan the advertising data from a peripheral (device name, peer address, raw data etc.) and output it via UART on a terminal programm. The output isen-USTelligent Community 13Wed, 13 Jul 2016 14:36:00 GMThttps://devzone.nordicsemi.com/thread/57739?ContentTypeID=1Wed, 13 Jul 2016 14:36:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a45e3808-740a-419d-8c18-2467125656b7Ole Bauck<p>You have probably used up the UART TX buffer which is set up to 256 bytes in the ble_app_uart example. When the buffer/fifo is full bytes will be dropped (printf does not care about the NRF_ERROR_NO_MEM return value).</p> <p>You are printing alot of text in the event. Remember that sending data over UART actually takes time. Running at 115200 baud with one start bit and one stop bit the data rate is about 11.5 kB/s. Increasing the buffer may fix your problem, but if you get too many events you may experience that the buffer will still be filled up some times. You should consider using RTT instead (with enough buffer set up), or print less text.</p><div style="clear:both;"></div>
