[SOLVED] Recommended method for writing LOG messages during RUNTIME?

[Steph van Schalkwyk]

I've tried ble_app_uart, nrf_serial.c etc. and none seems satisfactory.

I can write to the logger logger/uart during DEBUG, but it doesn't seem to succeed in RUN.

Question:

1. Can SEGGER_RTT be used in RUN build?

2. Can NRF_LOG (_INFO etc.) be used in RUN build, or is it only in DEBUG?

3. I have tried to get nrf_serial.c (nrf_serial_write() etc.) in RUN and I can't seem to get it working.

4. What is the recommended method to get messages out in Runtime?

UPDATE

I am using nrf_serial.c  with UART in legacy mode and set to POLLING. It is writing enough debug data (in RUNTIME) for now.

Caveat: If you're using nrf_serial, make sure your code doesn't have any printf statements - it crashes the code.

I also turned REDIRECT off.
