NRF LOG not working in ble_app_uart example

[jithin m das]

I'm using nrf52 with S132. I was trying ble_app_uart example and it is not printing any log messages into the COM. Do I need to do anything extra to make it work?

Hi,

Since the UART peripheral is in this example used by the application directly, it’s not recommended to use it as a backend for the nrf_log also, since there is no mechanism for managing access to uart. The option to select the UART as nrf_log backend in the ble_app_uart example is therefore removed in SDK 14.

You should therefore instead use the Seggert RTT viewer to view the nrf_log messages.

Make sure that you have the NRF_LOG_PROCESS() in the main loop.

// Enter main loop.
for (;;)
{
    if (NRF_LOG_PROCESS() == false)
    {
        power_manage();
    }
}

and open the program J-Link RTT Viewer to view the log messages.
