SDK12 app_uart.c issue

[OskarM]

Hi, I have such code:

static buf[9] = {initializers};
for(i =0;i <9;i++){
		while(app_uart_put(buf[i]));
}

I always get "0" before the actual buf content and the last byte isn't sent; In need to add manually:

while(app_uart_put(buf[8]));

to print out the last byte.

If I repeat the loop - printouts will start with the last byte from the first loop and again the last byte won't be sent.

Is this a bug or I don't understand how does this f-n work?

regards

Can you give us a more detailed example that will reproduce the issue, I don't see what the problem can be. Have you tested using app_uart_fifo.c instead?
