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?

Hello,

I don't think we have any example code showing you how to use the RXTO event directly, but it also doesn't do what you describe. The RXTO event is triggered if you use the STOP task register. 

From what I understand from your question, you want to receive a buffer after a certain time, perhaps from the first byte. Is that correct? If so, you can look into the peripheral_uart sample found in NCS\nrf\samples\bluetooth\peripheral_uart.

In this sample, you will get a callback when the UART receives some bytes, and then stops. After a given amount of time, the UART will trigger a callback with all the bytes received before the timeout.

Best regards,

Edvin

hi Edvin,

I want to receive a buffer after a certain time. The peripheral_uart  use uart_rx_enable to enable uart. But I want to use uarte because of easy dma.Do you any uarte example code?
