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.

I checked uart_irq_tx_ready() function it return 0 but I don't have infinite loop. ovrebekk

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

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.
