NRF9160 DK UART configuration

[Hkhan7861]

Hi

I am currently running and adjusting the zephyr echo_bot uart sample
on my nrf9160 DK. Currently , the sample makes use of UART0 to send a receive information which I have made compatible with an external device and the nrf terminal. My issue is that configuring the exact code to UART1 or UART0 has been difficult to achieve. Please assist.

Hi again

I've created the overlay file, used the code you provided and the echobot does not work.  In my understanding, the program should display an output using the LTE link monitor or the or the VS built in serial monitor.  Please assist urgently.  Do I need to add some code in the prj.config file as well?

Thank you

Thank you Naeem! this has helped.

The entire project is to collect a data from an Arduino and send it to an mqtt server.  I'm currently using the mqtt_simple code as well as the echo_bot code.  The intention is to collect the data a d UART1 and send it to the console(UART 0).  The issue is, when I begin to use UART0 as the shell, the LTE connection fails.

does this make sense? if so, is there a way around it?

Thank you !
