https://devzone.nordicsemi.com/f/nordic-q-a/62497/nrf9160-uart-rts-ctsHi , I want to know if it is possible to close/open the uart connection with RTS and CTS pin in order to have a low power UART? When RTS and CTS are high, uart is closed When RTS or CTS are low, uart is opened If yes, how to do that?

When CTS is de-asserted (high), you turn of UART and make the device sleep, and when CTS is asserted (low) you wake up the device and continue the communication.</p> <p>If you have problems implementing this, please ask and I will try to assist.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
