https://devzone.nordicsemi.com/f/nordic-q-a/73904/nrf52dk-uart-flow-controlHi, what is the nRF52DK UART, for the nRF52832, flow control when using the ble_app_uart_pca10040_s132 example? It appears to be possible interrupt driven based on data received (UART to UART)? As shown in this figure - assuming that level shift fromen-USTelligent Community 13Tue, 13 Apr 2021 15:46:07 GMThttps://devzone.nordicsemi.com/thread/304646?ContentTypeID=1Tue, 13 Apr 2021 15:46:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1a7910fb-4c99-46c7-80d4-d673e9f4e2e7blue-sky-iot<p>Hi, thanks for the response - was looking for confirmation that the UART was interrupt flow control and input (more info).</p> <p></p> <p>Thanks for both.</p> <p>Bob</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/304602?ContentTypeID=1Tue, 13 Apr 2021 14:09:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:36f0a2f1-e6dd-4777-8634-eafc4749eb62Kenneth<p>Hi,</p> <p>Not sure if I see any specific question here, but there is no need to configure or use flow control, but there are some advantages using flow control such that&nbsp; you don&#39;t overrun buffers and also you may get lower power consumption values, since enabling uart continuously will draw about ~1mA. In any case I recommend you to check out the libuarte for a robust uart library:<br /><a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/libuarte_example.html">https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/libuarte_example.html</a></p> <p>The uart peripheral use interrupts yes, if flow control is not used, then you free up 2 pins (CTS and RTS) that can be used for other purpose.</p> <p>Kenneth</p><div style="clear:both;"></div>
