rpi 3 ethernet gateway to serial rs485

[trentbliss]

Hi

I have set up my rpi 3 b+ with raspbian lite to the following page.

https://forum.mysensors.org/topic/6960/raspberry-pi-3-as-gateway-using-rs485

./configure --my-rs485-serial-port=/dev/serial0 --my-gateway=ethernet --my-port=5003 --my-transport=rs485 --my-rs485-baudrate=9600 --my-rs485-de-pin=37 --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18

pi@raspberrypi:~/MySensors $ sudo ./configure

pi@raspberrypi:~/MySensors $

When i run the code i get

pi@raspberrypi:~/MySensors $ sudo ./bin/mysgw
Sep 23 03:33:43 INFO  Starting gateway...

Sep 23 03:33:43 DEBUG MCO:BGN:STP
Sep 23 03:33:43 DEBUG MCO:BGN:INIT OK,TSP=1

then i use cas modbus scanner to send a command

then i get

Sep 23 03:33:51 DEBUG New connection from 192.168.6.66
Sep 23 03:33:51 DEBUG GWT:TSA:C=0,CONNECTED

But nothing else happens. I then manually disconnect CMS

Sep 23 05:25:11 DEBUG GWT:TSA:C=0,DISCONNECTED
Sep 23 05:25:11 DEBUG Ethernet client disconnected.

When i do a write command CMS says it was successful but it didn't send command to my device.

When i write a read holding register command it replies with unknown error.

Can anyone point me to where this is not working correctly.

Welcome to the MySensors forum @trentbliss

Could you explain what CMS is in this context?

What is a read holding register command?
