Hi 

Are you using one of the standard SDK examples?

There is an app_uart_flush() function for flushing the buffers when using the app_uart driver, but it will not do anything unless you make sure to use the app_uart_fifo.c implementation. 

When you say you cannot find this function, do you mean that the build fails if you try to call it?

The function is declared on line 244 of app_uart.h, and implemented on line 186 of app_uart_fifo.c

Best regards

Hi 

Which example are you using?

If you open the ble_app_uart example for instance both app_uart.h and app_uart_fifo.c should already be added to the project. 

Best regards
