It may be better to use UART for logging in the application. I can be tricky to get RTT logging to work across different applications. Here is another forum thread that covers the issue in more detail: https://devzone.nordicsemi.com/f/nordic-q-a/20708/rtt-logging-from-application-started-by-bootloader
