* The MySensors Arduino library handles the wireless radio link and protocol

/**
* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

*******************************
*
* DESCRIPTION
* The RS485 Gateway prints data received from sensors on the serial link.
* The gateway accepts input on seral which will be sent out on
* the RS485 link.
*
* Wire connections (OPTIONAL):
* - Inclusion button should be connected between digital pin 3 and GND
* - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
*
* LEDs (OPTIONAL):
* - To use the feature, uncomment MY_LEDS_BLINKING_FEATURE in MyConfig.h
* - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
* - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
* - ERR (red) - fast blink on error during transmission error or recieve crc error
*
* The gateway uses AltSoftSerial to handle two serial links
* on one Arduino. Use the following pins for RS485 link
*
* Board Transmit Receive PWM Unusable

* DESCRIPTION
* This is an example of sensors using RS485 as transport layer
