size_t write (uint8_t byte)

Writes a single byte to the remote UDP server. This function must be placed after AdafruitUDP.beginPacket() and

before AdafruitUDP.endPacket(). The packet will not be sent until .endPacket is called!

Parameters:

byte: The single byte to write to the transmit buffer

Returns: The number of bytes written.

size_t write (const uint8_t *buffer, size_t size)

Writes the specified 'buffer' to the remote UDP server. This function must be placed after AdafruitUDP.beginPacket()

and before AdafruitUDP.endPacket(). The packet will not be sent until .endPacket is called!

Parameters:

buffer: The buffer where the data to transmit is stored

size: The number of bytes contained in 'buffer'

This function must be called AFTER AdafruitUDP.parsePacket()!
