💬 Building a Raspberry Pi Gateway

[marceloaqno]

@Reza Yes, you can use rs485 in the RPi.

./configure --my-transport=rs485 --my-rs485-serial-port=<YOUR_SERIAL_PORT>

For more options, run:

./configure -h

[marceloaqno]

@LaMB95 No, I meant the options you used when you ran ./configure

@tiana
"The Broadcom SoC has three independant SPI interfaces, however only one of these is brought out to the GPIO connector, and that one SPI interface has 2 Chip enable lines."

@marceloaqno from the docs I assume it is the gateway that has to open up port 5003 but I guess it does not because it can't connect to the ethernet (for some reason) or am I wrong?

[Reza]

@marceloaqno
i means that without arduino and usb port, similar to raspberry gateway ( raspberry +nrf24)
i means connect rs485 module to GPIO raspberry pi :) with domoticz

@marceloaqno

I m sorry I m new to using a raspberry pi and its for a project.
But if this is not what you asked for could you be a little more specific :$

[ericvdb]

use sudo ;)

[marceltrapman]

Oh and one other thing, when I set the gateway up for MQTT it works.

[marceloaqno]

@marceltrapman

If you use the --my-controller-ip-address= option, the gateway will act as a client and attempt to conect to the supplied ip and port. If you want the gateway to open port 5003, omit this option.

[marceloaqno]

@Reza You could connect the rs485 to the RPi UART and use the option --my-rs485-serial-port=/dev/ttyAMA0, but you need to turning off the UART functioning as a serial console.

Or, to make things easier:
rs485 <==> TTL/USB <==> RPi

[Reza]

@marceloaqno
i am beginner and i can not turning off the UART functioning. . . also on some board usb port after power off/on lost and i should disconnect/connect cable... i test your steps serial gateway with raspberry and GPIO with virtual usb serial . and i see this problem solve and after power off/on gateway is connect .
i suggest that you add this commands to page of rs485 gateway step by step and update this .
(https://www.mysensors.org/build/rs485)

I thank you for hard working and trying

@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

[marceltrapman]

@marceloaqno nice, working now :+1:

Thank you...

[Reza]

@b0rmann
thank you friend , but i am sorry i am very beginner in raspberry pi . because i use vera before and with raspberry and orange pi i use recently. so i need a full steps for a rs485 gateway(wiring and commands . . .) i dont know what is ttyAMA0 ! i use a serial gateway with usb port with raspberrypi 3 but i have some problem , but with a raspberrypi gateway and use a virtual serial port (ttyUSB020) all of my problem resolve. but i have problem with wireless. so i want have a wiring network. i want a full steps for setup a rs485 module with raspberrypi 3(wiring and steps for install...) thank you for help

[Anduril]

Do I read that correctly, does this gateway also gives a ethernet link to a serial-only controller? How do I have to configure ip and port? In the build section I see no option to set them.

@ericvdb

Okay what could be the problem? :3

[marceloaqno]

@Reza There are many guides on the web teaching how to connect and use rs485 with the RPi. I recommend you start with them and when you are sure it is working, you add MySensors to the equation.

ok thank you :(

@Anduril
you will get all the build options for the mysgw with the command

./configure -help

Here you can configure all options like serial and ethernet

[Anduril]

just cloned and read the --help, but still I don't know how to use.
To make it a litte less abstract: I have a ethernet gateway (ESP8266) running at 192.168.38.19 with port 5003 to connect to. I want to have this accessible by a serial-only controller on the raspberry.

I tried to do this config and make afterwards, but starting gave only FAILs...

./configure --my-gateway=ethernet --my-controller-ip-address=192.168.38.19 --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway

~/MySensors$ sudo ./bin/mysgw -d
mysgw: Starting gateway...

I think my config is wrong and it tries to connect to a nrf24 at the rpi. So what's the correct config for my case?

Thanks in advance.
