Hi.
We need volume control for apple device. I've added parts of the HID kbd example to ANCS example. However I have problems adding the service to advertisement. I've put the BLE_UUID_HUMAN_INTERFACE_DEVICE_SERVICE & BLE_UUID_TYPE_BLE to advdata.uuids_complete -struct. It already has the ANCS as solicited UUID. Problem is that the ble_advertising_init returns code 7 (invalid parameter) after call. Isn't it possible to advertise both solicited and complete services?
Advetising init code: uint32_t err_code; ble_advdata_t advdata;
static ble_uuid_t m_adv_uuids[1]; /**< Solicitated UUID:s. */
static ble_uuid_t m_main_uuids[1]; /**< Implemented UUID:s. */
m_adv_uuids[0].uuid = ANCS_UUID_SERVICE;
m_adv_uuids[0].type = m_ancs_c.service.service.uuid.type;
m_main_uuids[0].uuid = BLE_UUID_HUMAN_INTERFACE_DEVICE_SERVICE;
m_main_uuids[0].uuid = BLE_UUID_TYPE_BLE;
// Build and set advertising data
memset(&advdata, 0, sizeof(advdata));
advdata.name_type = BLE_ADVDATA_FULL_NAME;
advdata.include_appearance = true;
advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
advdata.uuids_complete.uuid_cnt = sizeof(m_main_uuids) / sizeof(m_main_uuids[0]);
advdata.uuids_complete.p_uuids = m_main_uuids;
advdata.uuids_solicited.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
advdata.uuids_solicited.p_uuids = m_adv_uuids;
ble_adv_modes_config_t options = {0};
options.ble_adv_whitelist_enabled = BLE_ADV_WHITELIST_ENABLED;
options.ble_adv_fast_enabled = BLE_ADV_FAST_ENABLED;
options.ble_adv_fast_interval = APP_ADV_FAST_INTERVAL;
options.ble_adv_fast_timeout = APP_ADV_FAST_TIMEOUT;
options.ble_adv_slow_enabled = BLE_ADV_SLOW_ENABLED;
options.ble_adv_slow_interval = APP_ADV_SLOW_INTERVAL;
options.ble_adv_slow_timeout = APP_ADV_SLOW_TIMEOUT;
err_code = ble_advertising_init(&advdata, NULL, &options, on_adv_evt, NULL);
APP_ERROR_CHECK(err_code);
