NRF52833 UART FİFO FİLL

[Mmterkc]

Hi I work with ble on nrf52833 I want to send my collected ble datas with uart1.In my code poll out working but fifo fill doesn't work. Any basic simple for fifo fifo fill? When I tried printk I readed my datas with uart0. 

My code:

const struct device *uart1 = device_get_binding("UART_1");

int uartgittimi=uart_fifo_fill(uart1,"deneme123456789",15);

//int uartgittimi return 0

uart_poll_out(uart1, 'A');

//poll_out working

My config file:

CONFIG_UART_INTERRUPT_DRIVEN=y

CONFIG_UART_1_ASYNC=y

CONFIG_UART_0_ASYNC=y

Hi 

Have you tried to use the uart_tx() function instead?

There are quite a lot of restrictions regarding when you can use the uart_fifo_fill() function, as explained in the API documentation.

Hi, I tried uart_tx() function but it doesn't work. If any using ble and uart_fifo_fill, I can see where I did mistake in code. ovrebekk

Hi 

What if you set CONFIG_UART_INTERRUPT_DRIVEN=n ?

Then you should be able to use the standard API, including uart_tx(). 

I made a small example here showing how to use the UART driver in ASYNC mode.
