Libuarte - advanced UARTE driver - Problem with hardware flow controlhttps://devzone.nordicsemi.com/f/nordic-q-a/73266/libuarte---advanced-uarte-driver---problem-with-hardware-flow-controlWe are using the advanced UARTE library to get advantage of EasyDMA to receive data from a LTE module. We also implemented hardware flow control. THe problem is that the Nordic chip correctly de-asserts the RTS line to stop the data flow coming fromen-USTelligent Community 13Fri, 26 Mar 2021 12:06:21 GMTRE: Libuarte - advanced UARTE driver - Problem with hardware flow controlhttps://devzone.nordicsemi.com/thread/302124?ContentTypeID=1Fri, 26 Mar 2021 12:06:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e78eb6c8-d7bd-4e46-9129-a30657f4f004Vidar Berg<p>Hello,</p> <p>Flow control is fully controlled in the UART HW so a SW &#39;hack&#39; would most likely be required to assert RTS earlier. But are you using the driver with the <span><a title="nrf_libuarte_async" href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/lib_libuarte.html?cp=7_1_3_28_1#lib_libuarte_async">nrf_libuarte_async</a></span> library on top? I would tink could avoid this if you allocate sufficiently large RX buffers.</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
