NCS V2.02 Switch between ScanNoConect and ScanWithConnect

[DavidKaplan]

I have to switch between several different scanning modes.

I scan in passive mode to get all sensors' advertisements (no connection).

I scan in active mode to get a specific sensor's name (no connection).

I need also to scan and connect to a specific sensor.

Only in the bt_scan_init() function is the bt_scan.connect_if_match flag settable.

But I can't call the bt_scan_init() function twice in the program since there is a local static bt_le_scan_cb scan_cb variable which is never unregistered and no way to do so.

I have resolved this by adding an unregister statement before it registers as seen in my code snippet.

Is there a better way?

static struct bt_le_scan_cb scan_cb;
void bt_scan_init(const struct bt_scan_init_param *init)
{
	// ?!? below
	bt_le_scan_cb_unregister(&scan_cb);
    // ?!? above
	bt_le_scan_cb_register(&scan_cb);

	/* Disable all scanning filters. */
	memset(&bt_scan.scan_filters, 0, sizeof(bt_scan.scan_filters));

Thanks David

Hi, 

I think that's the way.

Is there a way to submit a change  request to the base code so I will not have to edit the code every new version?

Of course there may be a better way to achieve the same results.

Thanks David
