How to send log messages to RTT and stdio to UART in mesh sdk?

[Prasad]

I am experimenting with light_switch server example from mesh SDK 2.1.1 . I want to add UART functionality to this example. 

I referred to the ble_app_uart example from sdk15.0.0 and I have successfully merged the UART part into light_switch server example. My code get compiled and I am able to flash it to my nrf52 dev board but printf() and __LOG both are send to RTT.

I want to push the debug logs to RTT and printf() to UART. I know it can be done as it is already implemented in the ble_app_uart example but I dont know what is needed to achieve this?

Finally I got it to work the way I wanted!!

You have to include ../components/libraries/uart/retarget.c in your project and define the macro RETARGET_ENABLED = 1(I defined it project settings)

This devzone question was helpful.
