Hi,
I'm developing a BLE application for the nRF52 and I wish to use directed advertising and the whitelist.
I initialise the Bluetooth advertising using the following code :
static void advertising_init(void)
{
// Build advertising data struct to pass into @ref ble_advertising_init.
memset(&m_advdata, 0, sizeof(m_advdata));
//Only set up adv_data. Options will be set depending on if advertising will be enabled or not.
m_advdata.name_type = BLE_ADVDATA_FULL_NAME;
m_advdata.include_appearance = false;
m_advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
m_advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
m_advdata.uuids_complete.p_uuids = m_adv_uuids;
}
And
advertising_init();
options.ble_adv_whitelist_enabled = false;
options.ble_adv_directed_enabled = false;
options.ble_adv_directed_slow_enabled = BLE_ADV_SLOW_DISABLED;
options.ble_adv_directed_slow_interval = APP_ADV_INTERVAL_SLOW;
options.ble_adv_directed_slow_timeout = APP_ADV_TIMEOUT_IN_SECONDS;
options.ble_adv_fast_enabled = BLE_ADV_FAST_ENABLED;
options.ble_adv_fast_interval = APP_ADV_INTERVAL_FAST;
options.ble_adv_fast_timeout = APP_ADV_TIMEOUT_IN_SECONDS;
options.ble_adv_slow_enabled = BLE_ADV_SLOW_ENABLED;
options.ble_adv_slow_interval = APP_ADV_INTERVAL_SLOW;
options.ble_adv_slow_timeout = 0;
err_code = ble_advertising_init(&m_advdata, NULL, &options, on_adv_evt, NULL);
APP_ERROR_CHECK(err_code);
Then on reception of a command via Bluetooth, I modify the bluetooth settings using the following :
options.ble_adv_whitelist_enabled = true;
options.ble_adv_directed_enabled = true;
options.ble_adv_directed_slow_enabled = true;
options.ble_adv_directed_slow_interval = APP_ADV_INTERVAL_SLOW;
options.ble_adv_directed_slow_timeout = APP_ADV_TIMEOUT_IN_SECONDS;
err_code = ble_advertising_init(&m_advdata, NULL, &options, on_adv_evt, NULL);
APP_ERROR_CHECK(err_code);
I recieve the message "Starting direct advertisement." via debug but on trying to connect I notice that the name of our device (it was "ESQ") has now changed to "N/A".
I looked at this post for guidance devzone.nordicsemi.com/.../
But after having placed some debug output functions within name_encode(), I note that it function is never sending the short name.
I've also tried changing the bluetooth device name to simply "E" but I still have the same problem.
Any ideas ? Thanks Lee
