sdk17.0.2
so i am trying to flush rx/tx while the command execute
cannot find
app_fifo_flush()
or
app_uart_flush()
anyone know how to do it?
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

you mean I cannot clear the uart_rx tx
I mean I found a bug happened it randomly
for example sometimes when I type on the keyboard "connect AF:BF:CF:DF:EF:FF" but when I type to con or connect when I press the next character it with output random character on the uart so I wonder why is this happening(Seldom happen)
another thing is if I just copy-paste "connect AF:BF:CF:DF:EF:FF"
sometimes the output show up on uart wrong
it shows "connect??? AF:???BF:C???F:DF:EF:FF"
I am 100% sure I copy the correct string
for example
[15:06:31.505]OUT↙⊙connect 5C:F3:70:38:AE:36 ↓ [15:06:31.508]IN↘↑connect 5C:F3:70connect 5C:F3:70:38:Act 5CE6 [1;31mwrong parameter count
you can see the uart shows wrong what I copy on the uart
I copy it correctly but the Uart shows wrong
so I think if I can clean up the rx-tx in uart
or you know if there is any other problem
Hi
I just had a quick chat with the developer of the interactive example. Apparently there is no way to flush the buffers in this example because the UART functions are blocking.
Whenever there is something to send the nrf_cli_process() function will run until the entire message is written to the UART, so you don't need to separately flush the buffers.
Which terminal program are you using?
Have you tried with another one to see if the issue is the same?

yep First I use "putty" then I use "mobaXterm" Same problem still happened
now I use "sscom" still the same thing happened
I have tried three different terminal already
So I wonder if there is a way to clean up the RX/Tx or flow control at least
btw also I found out that if I send the message too fast the entire app will crash
For example:
If I press "tab" it will show all the commands which I can use
but as if I hold the tab and not release the "tab" button
the uart will keep printing the commands which I can use
after n time printing the program will crash
is this a bug??
or if there is a way to clean up the RX/Tx or flow control at least
Hi
Can you give me a bit more details on what you want to use this example for?
This example is not designed to be used in a product.
It is also in the experimental folder, which means we have only done limited testing on it.
Possibly there are other examples that are more suitable for what you are trying to accomplish.
Best regards
