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

01 FF 00 58 07 02 FF FF - FF 02 03 07 FF 03 66 04
01 FF 00 58 07 02 FF FF - FF 02 03 07 FF 03 66 04

@tekka said:

@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
