i am ready. after compiled and upload example node sketch i have on rs485 to usb convertor (/dev/ttyUSB0) output nice mysensors data:

@b0rmann The routing tables look messed up - maybe worthwhile sending a clear routing table command (using C_INTERNAL / I_CHILDREN / C) to all repeaters and observe how they are re-established.

problem solved after clearing routing via C_INTERNAL / I_DEBUG / E

no. rs485 must have LINEAR BUS topology.

Is it possible OTA from linux without MYSController?

yes, it's too hard

1. yes
2. gw nave not "sketch", it's raspberry pi port of gw

...

problem solved by using external power source on radio (instead 3v3 raspberry pi output)

@Reza

if you want use rpi /dev/ttyAMA0 for rs485 gateway -

1. remove string "console=serial0,115200" from /boot/cmdline.txt
2. add strings "enable_uart=1" and "dtoverlay=pi3-disable-bt" to /boot/config.txt (only on rpi3)
3. reboot raspi

@tekka

gateway has 5-10cm. node - on pcb

p.s. after clearing repeater node (#10) eeprom it looks better
