Hi,

I don't solve the problem but i avoid it.

in main.c :

const app_uart_comm_params_t comm_params = { RX_PIN_NUMBER, TX_PIN_NUMBER, RTS_PIN_NUMBER, CTS_PIN_NUMBER, //APP_UART_FLOW_CONTROL_ENABLED, APP_UART_FLOW_CONTROL_DISABLED, false, UART_BAUDRATE_BAUDRATE_Baud115200 };

I disable the FLOW CONTROL. I dont understand the problem because i configure "Termite" with flow control RTS/CTS.

If you have an idea, i'm aware :)

Thanks for your time

I search uicr_config.h example and i create mine in my project, i followed your solution but nothing change.

EDIT : After search, NRF51X422 doesn't have NFC antenna, so i'ts not the problem. I use a PCA10028

Hi, thanks for your anwser,

I'm using the next configuration :

#define RX_PIN_NUMBER  11
#define TX_PIN_NUMBER  9
#define CTS_PIN_NUMBER 10
#define RTS_PIN_NUMBER 8

and i searched the line to desable the NFC antenna pins.

The link you give to me is for NRF52832. infocenter.nordicsemi.com/.../nRF51822_PS_v1.0.pdf On the .pdf for nRF51x22, they are no information about this register.

I found this page : devzone.nordicsemi.com/.../group__uicr__config__example.html same as your link.

i didn' find "uicr_config.h" in my project.

Hi, thanks for your anwser. I ran the application in debug mode and use a breakpoint in nus_data_handler() function. When i sent a data from my phone to my board, i entered in the nus_data_handler() function. For the BLE_GATTS_EVT_WRITE, i found 2 function with this event : in ble_nus.c

void ble_nus_on_ble_evt(ble_nus_t * p_nus, ble_evt_t * p_ble_evt)
{
if ((p_nus == NULL) || (p_ble_evt == NULL))
{
    return;
}

switch (p_ble_evt->header.evt_id)
{
    case BLE_GAP_EVT_CONNECTED:
        on_connect(p_nus, p_ble_evt);
        break;

    case BLE_GAP_EVT_DISCONNECTED:
        on_disconnect(p_nus, p_ble_evt);
        break;

    case BLE_GATTS_EVT_WRITE:
        on_write(p_nus, p_ble_evt);
        break;

    default:
        // No implementation needed.
        break;
}
}

in ble_conn_params.c

void ble_conn_params_on_ble_evt(ble_evt_t * p_ble_evt)
{
switch (p_ble_evt->header.evt_id)
{
    case BLE_GAP_EVT_CONNECTED:
        on_connect(p_ble_evt);
        break;

    case BLE_GAP_EVT_DISCONNECTED:
        on_disconnect(p_ble_evt);
        break;

    case BLE_GATTS_EVT_WRITE:
        on_write(p_ble_evt);
        break;

    case BLE_GAP_EVT_CONN_PARAM_UPDATE:
        on_conn_params_update(p_ble_evt);
        break;

    default:
        // No implementation needed.
        break;
}
}

I use breakpoint in cases and nothing appear when i sent data from my phone to my board.

@Jean: Could you run the application in debug mode and check if the nus_data_handler() is called or BLE_GATTS_EVT_WRITE event is received ? I assume you have tested and the UART worked both direction (with the SDK's uart example)

What pin are you using for RX? If you're using pin 0.09 or 0.10 see this thread: devzone.nordicsemi.com/.../
