UART - Polling and Interrupt driven simultaneously

[Vitaliy Freidovich]

Hi,

I'm using nRF Connect SDK 1.7.1.

Is it possible to mix polling & interrupt driven UART API?

I have a situation in which I want to receive input once in a while via UART, which would naturally fit into an interrupt, and I have implemented via uart_irq_callback_set,

and unrelated to this, but based on a GPIO input, I'd like to transmit output via UART.

I tried to call uart_poll_out on a GPIO event, but it doesn't seem to send anything.

Any help would be appreciated!

Hi Vitaliy,

Thank you for the request. I will look into this and get back to you after the weekend.

Best regards,

Thanks @helsing, I resolved the issue, it was my mistake,

It is possible, and it works perfectly,

I just sent an 0 instead of '0', so it was not displayed over the terminal.
