I'm using nRF52840 with nRF5_SDK_17.1.0_ddde560, using the ble_app_multirole_lesc example file.
When I set extended = 1
in scan_init
, the debug session jumps to NRF_BREAKPOINT_COND
with the message:// On assert, the system can only recover with a reset.
How can I correctly enable extended scanning?
Below is my scan_init
configuration:
static void scan_init(void) { ret_code_t err_code; ble_uuid_t target_uuid = { .uuid = BLE_UUID_HEART_RATE_SERVICE, .type = BLE_UUID_TYPE_BLE }; 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; ble_gap_scan_params_t const m_scan_params = { .extended = 0, // Whenever I enable extended packet scanning, unidentified issues arise during runtime. .active = 0, .interval = NRF_BLE_SCAN_SCAN_INTERVAL, .window = NRF_BLE_SCAN_SCAN_WINDOW, .timeout = NRF_BLE_SCAN_SCAN_DURATION, .scan_phys = BLE_GAP_PHY_1MBPS, .filter_policy = BLE_GAP_SCAN_FP_ACCEPT_ALL, }; init_scan.p_scan_param = &m_scan_params; err_code = nrf_ble_scan_init(&m_scan, &init_scan, scan_evt_handler); APP_ERROR_CHECK(err_code); if (strlen(m_target_periph_name) != 0) { err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_NAME_FILTER, m_target_periph_name); APP_ERROR_CHECK(err_code); } err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_UUID_FILTER, &target_uuid); APP_ERROR_CHECK(err_code); err_code = nrf_ble_scan_filters_enable(&m_scan, NRF_BLE_SCAN_NAME_FILTER | NRF_BLE_SCAN_UUID_FILTER, false); APP_ERROR_CHECK(err_code); }
