Hi,
The project is based on nrf cloud reset FOTA sample, ncs 2.6.1, testing on nrf9160DK. I use a FT232 to monitor the output from uart2.
I want:
uart0: used for outputting system logs via the console.
uart2: used for interactive shell commands and SMP
The issue is that I see all the LOG_INF, LOG_ERR message printed to both uart0 and uart2.
I only want uart0 to log console info and uart2 for shell and SMP.
Can you please check where I was wrong:
