Hi, I'm developing an application which is merging from (ble_app_uart + libuarte + app_timer + pwm).
Here is my main.c
Now I'm developing an feature that using timer ((app_timer) for low power consumption than timer). And every 10s, libuarte will be uninit to save energy.
I can run the app timer but when I uncomment lines from 822 to 825 => my debug terminal got this problem
Here is my main.c
