the NRF_LOG_INFO macro

[SuperPoorUser]

Hi:

I'm using "nRF5_SDK_17.0.2_d674dde"

A question about the macro NRF_LOG_INFO.

the statement in the source code NRF_LOG_INFO("Disconnected connection handle");

=> In example "ble_app_uart", the log messages lead to RTT viewer only

=> In example "ble_app_buttonless_dfu", the log messages show both in hyper-terminal and RTT viewer

=> in example "dfu", there's no any log until ble_app_buttonless_dfu starts and show partial messages in RTT viewer.

How can I configure it correctly, if I want observe the messages all on RTT view or hyper-terminal?

Hi,

The examples that you listed use different backends for the logger module. If you want view the log output in RTT viewer than you have to use RTT as the logger backend. Namely, 

NRF_LOG_BACKEND_RTT_ENABLED 1

has to be set in your project config file. Documentation on the logger module can be found here.
