Hello Andhika,

I got a similar issue with you before (SDK 14.x.x) and the cause for that was I did not add the function gatt_evt_handler in function static void gatt_init(void). I don't know if you used to have it or not. Anyway, I found that you have fixed it.

/**@brief Function for initializing the GATT module.
 */
static void gatt_init(void)
{
    APP_ERROR_CHECK(nrf_ble_gatt_init(&m_gatt, gatt_evt_handler));
    APP_ERROR_CHECK(nrf_ble_gatt_att_mtu_periph_set(&m_gatt, NRF_SDH_BLE_GATT_MAX_MTU_SIZE));
}

Best regards,

Duy

Hi,

thank you fro your respond it seem the problem lies on uuid, i already made a seperate post abou it but here

static ble_uuid_t m_adv_uuids[] =                                               /**< Universally unique service identifiers. */
{
    {BLE_UUID_DEVICE_INFORMATION_SERVICE, BLE_UUID_TYPE_BLE}
};

it's from ble_app_template

when I use these uuid my device could be found but the service it's not what i want

i chang it to these:

static ble_uuid_t m_adv_uuids[] =                                               /**< Universally unique service identifiers. */
{
		{BLE_UUID_NUS_SERVICE, NUS_SERVICE_UUID_TYPE }
};

and comes that problem my device could not be found.

and i'm using eclipse, i using ses just for modifying the nus first.

I asked my friend about nrf_break_cond, who worked at this project before, he said it's not a problem, because it's also happened to him but the programm worked anyway.

Hi,

Can you attach the callstack before you hit nrf_breakpoint_cond? If you are using Segger Embedded studio go to Debug and then press F5.

Hallo Duy,

I also already enabled the ble_nus in sdk_config.

Hello Andhika,

Have you enabled the services, put the NUS UUID in and removed the redundants functions? I think there should be some things wrong during the initialization. Also watch for the sdk_config.h file.

Best regards,

Duy
