static struct wl_network_t* find_best_candidate ( struct cm *  cm )

static

This function can be modified to pick a network based on application specific criteria.

If the SSID can not be found in the scan list it will be assumed to be a hidden SSID and the wl_connect() command will be called to attempt to probe for the network and connect to it.

wl_err_t wl_cm_set_network	(	struct wl_ssid_t *	ssid,
		struct wl_mac_addr_t *	bssid
	)

Set the desired network which the connection manager should try to connect to.

The ssid and bssid of the desired network should be specified. The ssid and bssid will be matched against the networks found during scan. If any parameter is null, it will always match. If both parameters are null, the first found network will be chosen.

Parameters

ssid	The ssid of the desired network. If null, any ssid will match.
bssid	The bssid of the desired network. If null, any bssid will match.

Doesn't actually start the CM, just initializing.

CM will run whenever an valid ssid is set through wl_cm_set_network().
