NRF_LOG_BACKEND_UART work with NUS

[York]

Hello,I want to make NRF_LOG_BACKEND_UART work with NUS . The nus work with app_uart_fifo,and the NRF_LOG_BACKEND_UART work with app_uart. I try to make them work together,but It doesn't work.What can i do for it.I don't understand NRF_LOG_INFO(),how it works with app_uart.

Hi,

Since the UART peripheral is in the ble_app_uart 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 Segger RTT viewer to view the nrf_log messages. (NRF_LOG_BACKEND_RTT_ENABLED set to 1)

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.
