Help me please!!!
nRF52840 DK stops to scan after 3 hours working.
Project is based on central_nordic_uart_service.
Scan params
struct bt_le_scan_param scan_param = {
.type = BT_SCAN_TYPE_SCAN_ACTIVE,
.interval = 220,
.window = 80,
.options = BT_LE_SCAN_OPT_CODED | BT_LE_SCAN_OPT_NO_1M
};
struct bt_le_conn_param conn_param = {
.interval_min = 1000,
.interval_max = 1000,
.latency = 0,
.timeout = 2000,
};
struct bt_scan_init_param scan_init = {
.connect_if_match = 0,
.scan_param = &scan_param,
.conn_param = &conn_param
};
bt_scan_init(&scan_init);
bt_scan_cb_register(&scan_cb);
err = bt_scan_filter_add(BT_SCAN_FILTER_TYPE_UUID, BT_UUID_NUS_SERVICE);
if (err)
{
LOG_ERR("Scanning filters cannot be set (err %d)", err);
return err;
}
err = bt_scan_filter_enable(BT_SCAN_UUID_FILTER, false);
if (err)
{
LOG_ERR("Filters cannot be turned on (err %d)", err);
return err;
}
LOG_INF("Scan module initialized");
return err;
it works fine 3 hours and then BLE doesn`t able to scan any peripheral.
Connected devices are working fine until it disconected, and then they can not to connect - no any feedback on central side.
I tried to reinit, start, stop scan - nothing helped.
