bm_lpuarte_rx_enable()

int bm_lpuarte_rx_enable

(

struct bm_lpuarte *

lpu

)

#include <bm_lpuarte.h>

Enable the receiver.

The event handler will be called from the caller context with the NRFX_UARTE_EVT_RX_BUF_REQUEST event. The user may respond and provide a buffer using bm_lpuarte_rx_buffer_set. An error is returned if buffer is not provided. After that, the receiver is started and another NRFX_UARTE_EVT_RX_BUF_REQUEST is generated. If a new buffer is not provided, then the receiver is disabled once the first buffer becomes full. If a new buffer is provided, then the receiver will seamlessly switch to a new buffer (using a hardware shortcut).

Parameters

[in]

lpu

Low Power UARTE driver instance structure.

Return values

0	Receiver successfully enabled.
-EBUSY	When receiver is already enabled.
