Configuretion is the following: i have specify RX buffer (128 bytes) in init function, and in order to get to NRF_DRV_UART_EVT_RX_DONE every 10ms call nrf_drv_uart_rx_abort(&amp;uart_insten-USTelligent Community 13Tue, 25 Jun 2019 11:24:02 GMThttps://devzone.nordicsemi.com/thread/194620?ContentTypeID=1Tue, 25 Jun 2019 11:24:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:320bb025-e56c-4f52-85ef-a35aa7d548bdhaakonsh<p>I suggest you look into the&nbsp;experimental libuarte library&nbsp;as it has already implemented similar functionality, but double/triple buffered. See sdk15.3\components\libraries\experimental_libuarte.<br /><br />You can call&nbsp;<span>nrf_drv_uart_rx_abort whenever you like, but you might get framing errors. The only way to deal with framing errors is to uninitialize and re-intialize the uart driver.&nbsp;</span></p><div style="clear:both;"></div>
