scan filters for custom uuid is not matching

hi attached code for below requirement:

command: scan on - scan devices

command: devices - display filtered devices .

Filters set are for : thermometer, NUS and custom service for nonin sensor.

but i could able to get only thermometer in peripheral device list.

please check and let me know what is wrong with the code.

i am using : SDK 15.02 nRF52832

ble_cus.hsdk_config.h\

i have modified ble_app_cli example code to achieve my requirements. attached files main.c, sdk_config.h, ble_cus.c(custom service), ble_cus.h

  • please debug the code if possible.i have attached all necessary files.

    Thanks,

    Rekha

  • Please send a project that I can compile. I don't understand the files that you have attached. Are they for the central (scanner) or the peripheral (advertiser)?

    your scanner/central. Have you tried to do some debugging? Turn off optimization, and see whether adv_uuid_compare() returns true and false. 

    How do you add the scan UUID filters?

    static void scan_init(void)
    {
        ret_code_t          err_code;
        nrf_ble_scan_init_t init_scan;
    
        memset(&init_scan, 0, sizeof(init_scan));
    
        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_UUID_FILTER, &m_nus_uuid);
        APP_ERROR_CHECK(err_code);
        err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_UUID_FILTER, &uuid2);
        APP_ERROR_CHECK(err_code);
        err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_UUID_FILTER, &uuid3);
        APP_ERROR_CHECK(err_code);
        err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_UUID_FILTER, &uuid4);
        APP_ERROR_CHECK(err_code);
    
        err_code = nrf_ble_scan_filters_enable(&m_scan, NRF_BLE_SCAN_UUID_FILTER, false);
        APP_ERROR_CHECK(err_code);
    }

    Like this?

    If you want me to test something, you must zip the project folder. If you are working on the ble_app_uart_c example, you must zip the folder:

    SDK\examples\ble_central\ble_app_uart_c.

    You are using SDK15.2.0, right?

  • yes i am using SDK15.2. sure i will zip and attach file

  • i am unable to attach complete folder getting error while uploading..

    You can test using SDK examples -> Peripheral -> ble_app_cli  project.

    only you need replace two files from that project folder :1 main.c 2. sdk_config.h these two files you replace from example code folder to my files which i have attached.

    and two files you need to add : ble_nus.c and ble_nus.h

    nothing else has been changed.

    let me know if you need any detailes.

    Thanks

    Rekha

  • So you mean the example:

    SDK15.2.0\examples\ble_peripheral\experimental\ble_app_cli? This example doesn't scan.

    I suggest you start with the ble_app_uart_c example found in

    SDK15.2.0\examples\ble_central\ble_app_uart_c
