Print Debug message via RTT in \peripheral\twi_scanner project of SDK15.2

[chianglin]

Hi,

I am testing I2C interface by using \peripheral\twi_scanner project of SDK15.2.

I found it can not print debug message to RTT interface, even these has one command "NRF_LOG_INFO("TWI scanner started.")".

How can I enable of  RTT output in this demo code?

Thank you,

Chianglin

By default, the TWI Scanner project sends the NRF_LOGs to the UART.

To configure for RTT, See:
