◆ espSimpleNowBroadcastData()

uint8_t espSimpleNowBroadcastData	(	char *	data,
		uint16_t	len )

Simple binary data tx NB max size 250Byte pls use max 249 just to be sure

◆ espSimpleNowCallbackDataSent()

void espSimpleNowCallbackDataSent ( const bool success )

The callback you shall implement as to check if data has been send NB esp now do not guarantee if data is received in same order as you did tx - ifff you are heavily loading the system

void espSimpleNowCallbackDataSent(const bool success) { }

to check if data has been send to get data

void espSimpleNowGetMacAddr ( uint8_t mac[6] )

you can get current mac addr

Returns: 1: hej

◆ espSimpleNowInit()

uint8_t espSimpleNowInit ( uint8_t macAddrLastByte )

change last byte in MAC to To used for broadcast See esp now library NB parm must not n´edn on 1,3,5,7 (decimal) or just lsb bit must not be 1 return: -1 if macaddressbyte i odd - must be even (lsb bit0 ==0) rest of err codes comes from call to initESPNowMac 1: esp_wifi_sec_mac failed 2: esp_now_init failed 3: esp_wifi_set_protocol failed 4: esp_now_register_send_cb failed 5: esp_now_register_recv_cb failed 6: esp_now_add_peer failed

espNowSimpleErr (of type esp_err_t) holds the actual errorcode
