How to communicate via UART from nrf5340 to an external customer board ?https://devzone.nordicsemi.com/f/nordic-q-a/113525/how-to-communicate-via-uart-from-nrf5340-to-an-external-customer-boardHi, I am newbie to the nordic world. I am trying to developing an application that allows me to send data via UART (&quot;not using the ble &quot; )from nordic nRF5340 board and read that data with in the Customer board . i tried the echo bot application , hereen-USTelligent Community 13Wed, 31 Jul 2024 10:09:32 GMTRE: How to communicate via UART from nrf5340 to an external customer board ?https://devzone.nordicsemi.com/thread/496383?ContentTypeID=1Wed, 31 Jul 2024 10:09:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:72a2c9a0-85cd-4600-b203-848ac4c6a635Mohseen Ahamad<p>yeah ! now it is working .

Just that in stead of shorting the Rx and Tx pins you connect the Rx and Tx pins to the custom board.
