Hi Nordic DevTeam,
So I already followed this tutorial on how to add custom service UUID.
https://github.com/NordicPlayground/nRF5x-custom-ble-service-tutorial
I have 3 services that I want to add DFU, NUS and Custom, and probably more Custom UUID later.
I kept getting error 12 (NRF_ERROR_DATA_SIZE) on the ble_advertising_init() even though I already updated the #define NRF_SDH_BLE_VS_UUID_COUNT 3 (I assume it's 3 because DFU, NUS and Custom?)
Here's my code :
static ble_uuid_t m_adv_uuids[] = /**< Universally unique service identifier. */
{
{BLE_UUID_NUS_SERVICE, NUS_SERVICE_UUID_TYPE},
{CUSTOM_SERVICE_UUID, BLE_UUID_TYPE_VENDOR_BEGIN}
};
...

/**@brief Function for initializing services that will be used by the application.
*/
static void services_init(void)
{
uint32_t err_code;
ble_nus_init_t nus_init;
nrf_ble_qwr_init_t qwr_init = {0};
ble_cus_init_t cus_init;
// Initialize Queued Write Module.
qwr_init.error_handler = nrf_qwr_error_handler;
err_code = nrf_ble_qwr_init(&m_qwr, &qwr_init);
APP_ERROR_CHECK(err_code);
// Initialize NUS.
memset(&nus_init, 0, sizeof(nus_init));
nus_init.data_handler = nus_data_handler;
err_code = ble_nus_init(&m_nus, &nus_init);
APP_ERROR_CHECK(err_code);
// Initialise CUS Service init structure to zero.
memset(&cus_init, 0, sizeof(cus_init));
err_code = ble_cus_init(&m_cus, &cus_init);
APP_ERROR_CHECK(err_code);
// BEGIN Block Added for DFU
// ONLY ADD THIS BLOCK TO THE EXISTING FUNCTION
// Initialize the DFU service
ble_dfu_buttonless_init_t dfus_init =
{
.evt_handler = ble_dfu_buttonless_evt_handler
};
err_code = ble_dfu_buttonless_init(&dfus_init);
APP_ERROR_CHECK(err_code);
// END Block Added for DFU
}

/**@brief Function for initializing the Advertising functionality.
*/
static void advertising_init(void)
{
uint32_t err_code;
ble_advertising_init_t init;
memset(&init, 0, sizeof(init));
init.advdata.name_type = BLE_ADVDATA_FULL_NAME;
init.advdata.include_appearance = true;
init.advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;// BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;
init.srdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
init.srdata.uuids_complete.p_uuids = m_adv_uuids;
advertising_config_get(&init.config);
init.evt_handler = on_adv_evt;
err_code = ble_advertising_init(&m_advertising, &init);
NRF_LOG_INFO("%d", err_code);
APP_ERROR_CHECK(err_code);
ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);
}
What's wrong with my initialisation bit?
