◆ cyw43_wifi_scan_active()

static bool cyw43_wifi_scan_active ( cyw43_t self)
inlinestatic

Determine if a wifi scan is in progress.

This method tells you if the scan is still in progress

Parameters
selfthe driver state object. This should always be &cyw43_state
Returns

◆ cyw43_wifi_set_up()

void cyw43_wifi_set_up ( cyw43_t self,
int  itf,
bool  up,
uint32_t  country 
)

Set up and initialise wifi.

This method turns on wifi and sets the country for regulation purposes. The power management mode is initialised to CYW43_DEFAULT_PM For CYW43_ITF_AP, the access point is enabled. For CYW43_ITF_STA, the TCP/IP stack is reinitialised

Parameters
selfthe driver state object. This should always be &cyw43_state
itfthe interface to use either CYW43_ITF_STA or CYW43_ITF_AP
uptrue to enable the link. Set to false to disable AP mode. Setting the up parameter to false for CYW43_ITF_STA is ignored.
