BLE manual connect and Disconnect

[Murugan]

Dear Nordic Team, 

Thanks for supporting.

I am working in ble_app_uart_c example in this example is automatically connect with its peripheral. But i need to connect and disconnect manually like  nRF_UART android app. please support anyone.

My HW = DK52

SDK = SDK15.2.0

now scanning process ok. little error in ble_evt_handler i am just modified ble_gap_evt_adv_report_t const * p_adv_report to ble_gap_evt_adv_report_t const * p_adv_report= &p_gap_evt->params.adv_report.

then i will try connection process in case any issue i will come back. Thank you.

@Einar Thorsrud  as per your suggestion set init_scan.connect_if_match = false scan the device list then try to connect like below 

init_scan.connect_if_match = true;
init_scan.conn_cfg_tag = APP_BLE_CONN_CFG_TAG;

err_code = nrf_ble_scan_init(&m_scan, &init_scan, scan_evt_handler);
APP_ERROR_CHECK(err_code);

err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_ADDR_FILTER, &GI8u_Device_List[GI8u_Device_ID-1][0]); 
APP_ERROR_CHECK(err_code);

err_code = nrf_ble_scan_filters_enable(&m_scan, NRF_BLE_SCAN_ADDR_FILTER, false);
APP_ERROR_CHECK(err_code);

after calling this function the system goes to reset. I thing filter setting may be wrong ?. please help further process.

Hi,

If the system goes to reset that is typically due to an APP_ERROR_CHECK. If you build debug version of the project and use logging, you should see which file, line and error code triggered this.

i want to know filter settings are correct based on SCAN_ADDR_FILTER ?

It should be straight-forward. You can see how it is used in two examples in SDK 15.2:

• examples\ble_central\ble_app_gatts\main.c (around line 693)
• examples\ble_central\ble_app_hrs_c\main.c (around line 882)
