Hi,
My problem was solved

There is some difference from Edvin thread I follow

in main.c

if (p_evt->data.rxtx.src == 0)
{
NRF_LOG_INFO("triggered by full buffer");
} else if (p_evt->data.rxtx.src == 1)
{
NRF_LOG_INFO("Triggered by timeout");
}

typedef struct
{
uint8_t * p_data; ///< Pointer to memory used for transfer.
size_t length; ///< Number of bytes transfered.
uint8_t src;
} nrf_libuarte_async_data_t;

case NRF_LIBUARTE_DRV_EVT_RX_DATA:
{

uint32_t rx_amount = p_evt->data.rxtx.length - p_libuarte->p_ctrl_blk->sub_rx_count;
if (rx_amount)
{
p_libuarte->p_ctrl_blk->rx_count += rx_amount;
nrf_libuarte_async_evt_t evt = {
.type = NRF_LIBUARTE_ASYNC_EVT_RX_DATA,
.data = {
.rxtx = {
.p_data = &p_evt->data.rxtx.p_data[p_libuarte->p_ctrl_blk->sub_rx_count],
.length = rx_amount,
.src = 0,
}
}
};

void nrf_libuarte_async_timeout_handler(const nrf_libuarte_async_t * p_libuarte)
{
NRFX_IRQ_DISABLE((IRQn_Type)NRFX_IRQ_NUMBER_GET(p_libuarte->p_libuarte->uarte));

uint32_t capt_rx_count = p_libuarte->p_libuarte->timer.p_reg->CC[3];

if (capt_rx_count > p_libuarte->p_ctrl_blk->rx_count)
{
uint32_t rx_amount = capt_rx_count - p_libuarte->p_ctrl_blk->rx_count;
nrf_libuarte_async_evt_t evt = {
.type = NRF_LIBUARTE_ASYNC_EVT_RX_DATA,
.data = {
.rxtx = {
.p_data = &p_libuarte->p_ctrl_blk->p_curr_rx_buf[p_libuarte->p_ctrl_blk->sub_rx_count],
.length = rx_amount,
.src = 1,
}
}
};
