It looks from the PinMap of the BLE Nitrogen board as it use the following pins for UART:

BLE_TX: 13
BLE_RX: 15
BLE_RTS: 12
BLE_CTS: 14

You need to change the pins in the examples if you are using our SDK.

i used Board BLE Nitrogen Terminal v1.9b or Com port toolkit And i mean chip has other Uart on which pins

In the UART peripheral example, the UART pins are set to the pins defined in the BSP header file. For nRF52 DK (PCA10040 board), this is defined as the following:

#define RX_PIN_NUMBER  8
#define TX_PIN_NUMBER  6
#define CTS_PIN_NUMBER 7
#define RTS_PIN_NUMBER 5

What terminal software are you using? Have you enabled flow control in the settings?

i modified function for it

static void nus_data_handler(ble_nus_t * p_nus, uint8_t * p_data, uint16_t length) 
{ 
    for (uint32_t i = 0; i < length; i++) 
    { 
        ble_nus_string_send(&m_nus, p_data,length); 
        // while (app_uart_put(p_data[i]) != NRF_SUCCESS); 
    } 
    // while (app_uart_put('\r') != NRF_SUCCESS); 
    // while (app_uart_put('\n') != NRF_SUCCESS); 
}

When i modified main

int main(void)
{
    uint32_t err_code;
    uint8_t dat_array[5]={'a','a','a','a','a'};
    bool erase_bonds;
    // Initialize.
    APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);
    uart_init();

    buttons_leds_init(&erase_bonds);
    ble_stack_init();
    gap_params_init();
    services_init();
    advertising_init();
    conn_params_init();

    printf("\r\nUART Start!\r\n");
    err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
    APP_ERROR_CHECK(err_code);
   	nrf_gpio_cfg_output(29);
    // Enter main loop.
    for (;;)
    {
    	ble_nus_string_send(&m_nus, dat_array, 5);
    	nrf_delay_ms(50);
        power_manage();
    }
}

i had mesage on my phone

yes i change it spechial for it because in nrf Uart on my Phone i cant sent '\n'

From the code you posted above, the data will only be sent when the char 'q' is found in the received string from UART, or the buffer is filled. Do you send a 'q' char in the string you send from the terminal?

this code send msg by Phone err_code = ble_nus_string_send(&m_nus, data_array, index);

and i chek i have conection in COM Port Toolkit.And i havent any msg

I'm not sure I understand your issue. The message you send from the phone is supposed to be transmitted to UART terminal, not echoed back to the phone. Have you edited the example in any way? The default example does check for the newline char '\n'. while your code looks like it looks for the char 'q'.
