OK, what I did:
on one Arduino nano I have this sketch
https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/examples/GatewaySerialRS485/GatewaySerialRS485.ino
on second arduino nano I have conbined two sketches:
https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/examples/DistanceSensor/DistanceSensor.ino
and
https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/examples/MotionSensorRS485/MotionSensorRS485.ino
and the results is:
/**
* 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.

* REVISION HISTORY
* Version 1.0 - Henrik Ekblad
*
* DESCRIPTION
* This is an example of sensors using RS485 as transport layer
*
* Motion Sensor example using HC-SR501
* http://www.mysensors.org/build/motion
*
* The transport uses AltSoftSerial to handle two serial links
* on one Arduino. Use the following pins for RS485 link
*
* Board Transmit Receive PWM Unusable
* ----- -------- ------- ------------
* Teensy 3.0 & 3.1 21 20 22
* Teensy 2.0 9 10 (none)
* Teensy++ 2.0 25 4 26, 27
* Arduino Uno 9 8 10
* Arduino Leonardo 5 13 (none)
* Arduino Mega 46 48 44, 45
* Wiring-S 5 6 4

On serial port (/dev/ttyUSB0) Controller (first nano) I see:
0;255;3;0;9;Starting gateway (RSNGA-, 2.0.0-beta)
0;255;3;0;9;Radio init successful.
0;255;3;0;14;Gateway startup complete.
0;255;3;0;9;Init complete, id=0, parent=0, distance=0
on serial port(/dev/ttyUSB1) in node is see:
...
Ping: 33 cm
Ping: 34 cm
Ping: 34 cm
Ping: 33 cm
Ping: 33 cm
Ping: 33 cm
Ping: 5 cm
Ping: 91 cm
Ping: 88 cm
Ping: 89 cm
......
But I expect to see some message on controller. What can I check? Do you see and mistakes ?
