I am currently trying to set up a filter to connect to a device based on its name. I will attach my scan init and scan start to show how I have this configured. I want to be able to connect to the device in the scan event handler when a match is found, but I am not hitting the breakpoint in that handler. I have set my target device to static char const target_device_name[] = "Bluetooth Pressure"; I have also attached the nRF Connect screen showing the device name. I am using sdk 17.0.2 as well.
static void scan_init(void)
{
ret_code_t err_code;
nrf_ble_scan_init_t init_scan;
memset(&init_scan, 0, sizeof(init_scan));
/**< Scan parameters requested for scanning and connection. */
init_scan.p_scan_param = &m_scan_param;
init_scan.connect_if_match = false;
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_NAME_FILTER, &target_device_name);
APP_ERROR_CHECK(err_code);
err_code = nrf_ble_scan_filters_enable(&m_scan, NRF_BLE_SCAN_NAME_FILTER, false);
APP_ERROR_CHECK(err_code);
}
