NRF_LOG_GETCHAR() is not suitable for our application. There are some routine processes in the main loop. However, we decided to implement App_Uart process to handle uart function at Rx / Tx. Thanks for everyone who advised.

Hi,

NRF_LOG_GETCHAR() is blocking, and returns when single byte is received. So it could be better to use app_uart_get() instead. Take a look at e.g. the ble_app_uart example and see how its done there.

But isn't NRF_LOG actually printf?

Can someone tell me that how to get a string using NRF_LOG_GETCHAR()? The following is my process, is it correct? c = NRF_LOG_GETCHAR(); NRF_LOG_INFO("%c", c);

I have found the way to get logs by interrupt at NRF_LOG setting. The configuration of "NRF_LOG_DEFERRED" should be clear to "0".
