I am developing with SDK 15.0.0
I want to add NUS service in ble_app_buttonless_dfu example.
All I have done:
1. Add including files and including paths to the project.
2. Combine sdk_config.h files.
3. Add NUS definition and services as needed. Here is the code:
BLE_NUS_DEF(m_nus, NRF_SDH_BLE_TOTAL_LINK_COUNT); /**< BLE NUS service instance. */
// YOUR_JOB: Use UUIDs for service(s) used in your application.
static ble_uuid_t m_adv_uuids[] = {
{BLE_UUID_DEVICE_INFORMATION_SERVICE, BLE_UUID_TYPE_BLE},
{BLE_UUID_NUS_SERVICE, NUS_SERVICE_UUID_TYPE}
};
/**@brief Function for initializing services that will be used by the application.
*/
static void services_init(void)
{
uint32_t err_code;
nrf_ble_qwr_init_t qwr_init = {0};
ble_dfu_buttonless_init_t dfus_init = {0};
// 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 the async SVCI interface to bootloader.
err_code = ble_dfu_buttonless_async_svci_init();
APP_ERROR_CHECK(err_code);
dfus_init.evt_handler = ble_dfu_evt_handler;
err_code = ble_dfu_buttonless_init(&dfus_init);
APP_ERROR_CHECK(err_code);
// Initialize NUS.
ble_nus_init_t nus_init;
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);
}
/**@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;
init.advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
init.advdata.uuids_complete.p_uuids = m_adv_uuids;
init.config.ble_adv_fast_enabled = true;
init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
init.config.ble_adv_fast_timeout = APP_ADV_DURATION;
init.evt_handler = on_adv_evt;
err_code = ble_advertising_init(&m_advertising, &init);
APP_ERROR_CHECK(err_code);
ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);
}
No error occurs in the compling and linking procedure.
But the device does not advertise. When I debug it with Keil, it stops at advertising_init() -> ble_advertising_init() -> // Copy advertising data:.ble_advdata_encode() -> // Encode 'complete' uuid list: uuid_list_encode() -> // Encode 16 bit UUIDs.: uuid_list_sized_encode() -> // Find encoded uuid size.: sd_ble_uuid_encode().
Inside the for loop of sd_ble_uuid_encode(), the function encoded two ble_uuid into the advertising data: DIS and NUS service. During the first loop, encoding DIS service, everything seems to be fine. However, during the second loop, encoding NUS service, the return err_code = 0x07 (NRF_ERROR_INVALID_PARAM).
I have compared with ble_app_uart example. In NUS example, running to Line 265, the value of uuid is the same.
I do not know why the error occurs.
