Doesn't enable the log backend of uart but the log output on the uart

[helen]

Hi

There is not NRF_LOG_BACKEND_UART_ENABLED in the sdk_config.h which in the ble_app_uart sample(nRF5_SDK_17.1.0_ddde560\examples\ble_peripheral\ble_app_uart\pca10040e)，I only set the NRF_LOG_BACKEND_RTT_ENABLED to 1 and the NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED to 0,but the log output both on the RTT and on the uart.I need RTT log only because the uart is used to output application data.I found that the log backend of uart is not initialized in the sample.

How to close the log output on the uart?

Hello,

The UART message is coming from the printf() in main(), not from the logger module. You can comment out this line if you want.
