SDK15 How to set scan data?

Question

Hi, 
 I have migrated from SDK14.1 to SDK15. 
 One thing is embarrassing me. 
 
 static test_params_t m_test_params =
{
 .att_mtu = NRF_SDH_BLE_GATT_MAX_MTU_SIZE,
 .conn_interval = CONN_INTERVAL_DEFAULT,
 .data_len_ext_enabled = true,
 .conn_evt_len_ext_enabled = true,
 // Only symmetric PHYs are supported.
#if defined(S140)
 .phys.tx_phys = BLE_GAP_PHY_2MBPS | BLE_GAP_PHY_1MBPS | BLE_GAP_PHY_CODED,
 .phys.rx_phys = BLE_GAP_PHY_2MBPS | BLE_GAP_PHY_1MBPS | BLE_GAP_PHY_CODED,
#else
 .phys.tx_phys = BLE_GAP_PHY_2MBPS | BLE_GAP_PHY_1MBPS,
 .phys.rx_phys = BLE_GAP_PHY_2MBPS | BLE_GAP_PHY_1MBPS,
#endif
}; 
 gatt_mtu_set(m_test_params.att_mtu);
data_len_ext_set(m_test_params.data_len_ext_enabled);
conn_evt_len_ext_set(m_test_params.conn_evt_len_ext_enabled);
preferred_phy_set(&m_test_params.phys); 
 I would like to modify the scan data as above, I do not know where I can fix it. 
 phy can be modified in the m_scan_params variable, I know that the MTU Size can be modified in the gatt_init () function. 
 Where can I modify data_len_ext_enabled and conn_evt_len_ext_enabled? Help me.

Hello, 
 
 Event length extension is set within the function nrf_sdh_ble_default_cfg_set(); which is typically called from main.c, and is defined in nrf_sdh_ble.c. 
 It uses the define NRF_SDH_BLE_GAP_EVENT_LENGTH from sdk_config.h, so that (sdk_config.h) is where you should modify your event length. 
 
 To update the data length extension, see the function sd_ble_gap_data_length_update(). It is also used in many of the examples. Documentation for the function is found on infocenter . 
 
 Best regards,
