Hi,

Looks like you are calling the SEGGER_RTT_printf function directly (not through NRF_LOG)? 

You need to include the source file in your project, found in: nRF5_SDK_12.3.0_d7731ad\external\segger_rtt\SEGGER_RTT_printf.c

And you need to define the preprocessor symbol 'NRF_LOG_USES_RTT=1'.

Best regards,
Jørgen
