Are you still having issues with this?

If so, maybe you can summarize your issue and what progress you have had so far, and open a new ticket?

Best regards
Torbjørn

Can you help me and tell me how it was done? (I will see your code)

But the handler is not included the RX data timeout procedure. You have to apply the RTC timer handler for timeout by your own.

Applay as this

static void uart_init(void)
{
uint32_t err_code;

const app_uart_comm_params_t comm_params =
{
.rx_pin_no = RX_PIN_NUMBER,
.tx_pin_no = TX_PIN_NUMBER,
//.rts_pin_no = RTS_PIN_NUMBER,
//.cts_pin_no = CTS_PIN_NUMBER,
.flow_control = APP_UART_FLOW_CONTROL_DISABLED, //APP_UART_FLOW_CONTROL_ENABLED,
.use_parity = false,
.baud_rate = UART_BAUDRATE_BAUDRATE_Baud115200
};

APP_UART_FIFO_INIT(&comm_params,
UART_RX_BUF_SIZE,
UART_TX_BUF_SIZE,
uart_event_handle,
APP_IRQ_PRIORITY_LOWEST,
err_code);

APP_ERROR_CHECK(err_code);
}

void uart_event_handle(app_uart_evt_t * p_event)
{
static uint8_t data_array[128];
static uint8_t index = 0;

switch (p_event->evt_type)
{
/**@snippet [Handling data from UART] */
case APP_UART_DATA_READY:
//UNUSED_VARIABLE(app_uart_get(&data_array[index]));
app_uart_get(&data_array[index]);
index++;

if ((data_array[index - 1] == '\n') || (index >=127))
{
data_array[index]=0;
index = 0;
memcpy(uart_rx_buff,data_array,sizeof(data_array));
}
break;
/**@snippet [Handling data from UART] */
case APP_UART_COMMUNICATION_ERROR:
