💬 Building a Raspberry Pi Gateway

[LaMB95]

ran sudo ./bin/mysgw -d
I keep getting mysgw: accept: Bad File Descriptor.
Any possible cause ?

[marceltrapman]

I am trying to get the raspi ethernet gateway running but on both my pi 3 (also running openHAB) and the pi B (pretty basic install).

Unfortunately I get the same error on both.

Any ideas what could be going on here?

I am running the latest gateway and the latest raspbian.

mysgw: Starting gateway...
mysgw: Protocol version - 2.1.0
mysgw: MCO:BGN:INIT GW,CP=RNNG---,VER=2.1.0

@marceltrapman

I am using a Rasp Pi 3 as well.
I can't even proceed further in the tutorial cause of this error cause nothing works after it.

@marceltrapman @LaMB95
Could you post the complete ./configure command used to configure the gateway?

[marceltrapman]

@marceloaqno Sure, forgot it :)

sudo ./configure \
    --my-gateway=ethernet \
    --my-controller-ip-address=192.168.1.xx \
    --my-port=5003 \
    --my-transport=nrf24

[marceloaqno]

@marceltrapman Are you sure it's not a problem with your controller?
Have you tried connecting to your controller using telnet?

telnet 192.168.1.x 5003

[LaMB95]

@marceloaqno !

Is this what you meant?

[marceltrapman]

@marceloaqno not sure no.

So, I downloaded telnet on the same raspi that I want to use as the gateway and the issue seems to be that port 5003 is not available.

Funny but how do I solve this.
It can't be an issue with the firewall because it allows all traffic on the internal network.

[marceltrapman]

@marceloaqno and the same from the controller to the gateway gives the same error on that port :(

[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."

[marceltrapman]

@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

[LaMB95]

@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 .

I thank you for hard working and trying
