Hi,
We're trying to add a custom service to the HID keyboard example. the service is initialized we can see the service when connected to the device from the nrfConnect app. but not in the adverting packet. we only see the HID service !
When using our phone app, in where we scan for a specific service UUID (custom service) the app can't find the device, but when scanning for hid service, the app can find it.
static ble_uuid_t m_adv_uuids[] = {
{BLE_UUID_HUMAN_INTERFACE_DEVICE_SERVICE, BLE_UUID_TYPE_BLE}
// {SM_SERVICE_UUID, BLE_UUID_TYPE_VENDOR_BEGIN}
};
using only the Custom service in the m_adv_uuids[], makes the ble_advertising_init(&m_advertising, &init); return and error ( INVALID PARAMETER ) .
/**@brief Function for initializing the Advertising functionality.
*/
static void advertising_init(void)
{
uint32_t err_code;
uint8_t adv_flags;
ble_advertising_init_t init;
memset(&init, 0, sizeof(init));
adv_flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
init.advdata.name_type = BLE_ADVDATA_FULL_NAME;
init.advdata.include_appearance = true;
init.advdata.flags = adv_flags;
init.advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
init.advdata.uuids_complete.p_uuids = m_adv_uuids;
//int8_t tx_power = -4;// Set Power Level
//init.advdata.p_tx_power_level = &tx_power;
init.config.ble_adv_whitelist_enabled = false;
init.config.ble_adv_directed_high_duty_enabled = true;
init.config.ble_adv_directed_enabled = false;
init.config.ble_adv_directed_interval = 0;
init.config.ble_adv_directed_timeout = 0;
init.config.ble_adv_fast_enabled = true;
init.config.ble_adv_fast_interval = APP_ADV_FAST_INTERVAL;
init.config.ble_adv_fast_timeout = APP_ADV_FAST_DURATION;
init.config.ble_adv_slow_enabled = false;
init.config.ble_adv_slow_interval = APP_ADV_SLOW_INTERVAL;
init.config.ble_adv_slow_timeout = APP_ADV_SLOW_DURATION;
init.evt_handler = on_adv_evt;
init.error_handler = ble_advertising_error_handler;
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);
}
note: we did set the NRF_SDH_BLE_VS_UUID_COUNT 1 , in the sdk_config file !
What we need to achieve, is to have that Custom service advertised. and not affecting the the HID service, meaning the host will still can see this device as a Hid device !
Thanks in advance,
best regards,
Abdelali
