Arduino for esp8266 Introduction to serial port function

Reference material ：https://arduino-esp8266.readthedocs.io/en/latest/reference.html#

A serial port

The object works in the same way as normal Arduino Work in much the same way . In addition to hardware FIFO（TX and RX by 128 byte ） outside , There is also an additional customizable 256 byte RX buffer . The size of this software buffer can be changed by the user . It is recommended to use larger capacity at higher receiving speed .NodeMcu There are two sets of serial ports ,Serial and Serial1.Serial Use UART0, The default corresponding pin is GPIO1（TX–D10） and GPIO3（RX–D9）

This method can be changed as needed RX Buffer size . This should be in Previous call .size The parameter should be at least large enough , In order to save all data received before reading .::setRxBufferSize(size_t size)::begin()
For transfer only operations &
