bool RF24::write	(	const void * 	buf,
uint8_t 	len 
)		
Be sure to call openWritingPipe() first to set the destination of where to write to.

This blocks until the message is successfully acknowledged by the receiver or the timeout/retransmit maxima are reached. In the current configuration, the max delay here is 60-70ms.

The maximum size of data written is the fixed payload size, see getPayloadSize(). However, you can write less, and the remainder will just be filled with zeroes.

TX/RX/RT interrupt flags will be cleared every time write is called

Parameters
buf	Pointer to the data to be sent
len	Number of bytes to be sent
radio.stopListening();
radio.write(&data,sizeof(data));
Returns
True if the payload was delivered successfully false if not
