@rejoe2 Thank you. #define MY_SPLASH_SCREEN_DISABLED that was the missing line.
Okey i understand now. Thank you again.

Hi all,
I have a question about, How to use hardware serial on Arduino Uno (as a sensor) to communicate with gateway via RS485? I added #define MY_RS485_HWSERIAL Serial and it is only working when i turn on debugging (#define MY_DEBUG), how to use hardware serial without debugger ?

I bought second arduino uno.

And, first Arduino has example MotionSensorRS485,
second Arduino has example GetwaySerialRS485.

And i have got the same situation. So even Gateway on Arduino doesn't see MotionSensor.

Next test i made, i disconnected MAX485 converters, and i connected UART pins from first arduino to the second one (UART = Rx(8) <-> Tx(9), Tx(9)<->Rx(8)) and GND. And i have got the same result. Gateway doesn't see sensor.

@mfalkvidd Okey, sorry.

Hi all,

I want to launch gateway on RaspberryPi with a RS485 network.
I downloaded the software (MySensors Library v2.4.0-alpha).
And i made coniguration:
./configure --my-transport=rs485 --my-rs485-serial-port=/dev/ttyUSB0 --my-rs485-baudrate=9600 --my-gateway=serial --my-serial-is-pty --my-serial-port=/dev/ttyUSB20 -my-serial-baudrate=115200 -my-serial-groupname=tty

I have USB-RS485 (it uses FT232RL) converter connected to the /dev/ttyUSB0.
On the other side i have Arduino uno with UART-RS485 (MAX485) converter, and a MotionSensorRS485 example on it.

After i made the program (make), and type sudo ./bin/mysgw, i've got this:

I'm able to add the hardware in domoticz (serial gateway ttyYSB20, 115200), but it doesn't see nodes.

Please help.

I checked the frames. And when i coneccted USB-RS485 to the computer i've got this in Realterm:

And next in python script on Raspbeery Pi i've got this:

So, i think the communication beetwen Raspberry Pi and Arduino is working (through USB-RS485 converter).

How should looks the frame of presentation, and sendSketchInfo ?

Okey, i know more.

So, I programmed Arduino using MotionSensorRS485 example.
And using monitor COM tool, i see this in arduino logs:

And by using this command:
./configure --my-gateway=serial --my-serial-is-pty --my-serial-port=/dev/ttyUSB020
im saying RaspberryPi to create the gateway that commucnicates with controller using virtual serial port (/dev/ttyUSB020),

and i think that by editing file examples_linux/mygw.cpp i'm choosing serial port for RS485 network (sensors network).

After i add the hardware to the domoticz controller, i've got this:

but still node is unknown.
Please help.

Hi All,

I want to make my Raspberry Pi a gateway of MySensors RS485 networ and controller of home automation using Domoticz.

Hardware i've got:

1. Raspberry Pi 4 (2GB RAM)
2. Converter USB <-> RS485 (it uses FTDI FR232RL chip) connected to the RPI
3. Converter RS485 <-> UART (MAX485)
4. Arduino Uno

I was trying to use this tutorial: https://www.mysensors.org/build/raspberry

But i think, i'm making something wrong.

After i connect the USB converter to the RPI i've got this answers:

1. ls -l /dev/tty* (images -> attachment: RPI1)
2. ls -l /dev/serial* (images -> attachment: RPI2)
3. ls -l /dev/serial/by-id/ (images -> attachment: RPI3)

What parameters should i use to configure this system correctly ?
I tried:
./configure --my-transport=rs485 --my-gateway=serial --my-serial-is-pty --my-serial-port=/dev/ttyUSB0 --my-serial-baudrate=115200

And:
./configure --my-transport=rs485 --my-gateway=serial --my-serial-is-pty --my-serial-port=usb-FTDI_FT232R_USB_UART_A50285BI-if00-port0 --my-serial-baudrate=115200

And what should i type in examples_linux/mysgw.cpp file (preprocessor definitions)? (images -> attachment: RPI4)

I made (make command) both configurations, and i've got the same ./bin/mysgw logs messages. (images -> attachment: RPI5)

To the RS485 network, i connected RS485 node example (MotionSensorRS485)

And at the end, how to cofigure domoticz hardware, when i want to use raspberry pi gateway?
