How to use the RXTO event trigger rx interrupt?

software:nRF CONNECT SDK 1.6.1

CPU type:nrf5340

module:uarte

hi professor,

I want to trigger receiving interrupt when receiving timeout.I see the product specification there are rxto event in nrf5340.Do you have any example code for me?

[sunnyyang]

The reason is p_cb-<handle is NULL.

Ok, so you are trying to trigger a callback at NULL, then. Why is it NULL? Did you not set up a handler when you initialized the UART?

BR,

I have used the uart_callback_set to set call back function.If don't use this function, what should I do？

What do you mean?

[sunnyyang]

I mean I have set callback by uart_callback_set function. But   the p_cb-<handle is still NULL.
