Flush UART

Question

Hello everyone, 
 I'm currently using and modifying the experimental_ble_app_uart. I've seen that for sending characters resp commands the file simple_get_uart is used. My question now is, if there is a way to flush the UART? 
 Thanks and best,
pingu

Hi Pingu, 
 If you are not using FIFO API for UART. 
 1.	STOPRX and STOPTX
2. UART->TXD = 0 // this is just to ensure predictable behaviour with flow control
3.	While(event_ready != 0){ clear event, read uart rxd}
4.	STARTTX and STARTRX
 
 When not using flow control -> TXD byte will be transmitted immediately when written and cannot be stopped.
