Using app_fifo_uart on SDK 9

[Ron]

I'm working with app_fifo_uart and I'm seeing that my event handler gets the event 'APP_UART_TX_EMPTY' repeatedly. Multiple times a second. Is there any reason for this? Can this be switched to only notify after tx buffer has sent all bytes rather than at all times?

I had the same issue with app_fifo_uart and I could not find solution. And I decided to use simple_uart.h. simple_uart.c. from SDK 6.
