◆ begin()

bool WifiEspNowBroadcastClass::begin	(	const char *	ssid,
		int	channel = `1`,
		int	scanFreq = `15000`
	)

Initialize ESP-NOW with pseudo broadcast.

Parameters

ssid	AP SSID to announce and find peers.
channel	AP channel, used if there is no STA connection.
scanFreq	how often to scan for peers (milliseconds).

void WifiEspNowBroadcastClass::end ( )

Stop ESP-NOW.

void WifiEspNowBroadcastClass::loop ( )

Refresh peers if scanning is due.

This should be invoked in Arduino sketch loop() function.

void WifiEspNowBroadcastClass::onReceive	(	WifiEspNowClass::RxCallback	cb,
		void *	arg
	)

inline

Set receive callback.

Parameters

cb	the callback.
arg	an arbitrary argument passed to the callback.

bool WifiEspNowBroadcastClass::send	(	const uint8_t *	buf,
		size_t	count
	)

inline

Broadcast a message.

Parameters

buf	payload.
count	payload size, must not exceed `WIFIESPNOW_MAXMSGLEN` .

bool WifiEspNowBroadcastClass::setKey	(	const uint8_t	primary[WIFIESPNOW_KEYLEN],
		const uint8_t	peer[WIFIESPNOW_KEYLEN] = `nullptr`
	)

Set encryption keys.

Parameters

primary	primary key, also known as KOK or PMK.
peer	peer key, also known as LMK; nullptr to disable encryption. The same peer key is applied to every discovered peer.
