https://devzone.nordicsemi.com/f/nordic-q-a/27898/how-to-disconnect-the-uart-when-data-is-not-transmittingHi! i am thinking about cut off uart when data is not transmitting. As a method 1, i am thinking about using CTS and RTS Pin which is hardware flow control! ①Is this possible?? ②also,Is there a sample code that achieves that? Now i am using the nRF52832en-USTelligent Community 13Thu, 07 Dec 2017 12:36:34 GMThttps://devzone.nordicsemi.com/thread/110084?ContentTypeID=1Thu, 07 Dec 2017 12:36:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f3ba8cfa-18f3-4e19-a35a-84b3fe7043acKaito<p>thanks! i solved the question!!!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/110083?ContentTypeID=1Fri, 01 Dec 2017 15:03:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:745e1f92-a4f0-4f16-b7cd-be5a899fc36cSigurd<p>Hi,</p> <p>Yes, this is possible.
