Using mqttGateway2.pl for Serial to MQTT on RaspberryPI

[aaron832]

Try typing

"uname -m"

into your console (that hosts the gateway). If it does not say
"armv6l" or "armv7l" (edit: correction)
then the Makefile will not include -lrf24-bcm in the LDFLAGS (libraries include). If this is the problem then what hardware are you making the gateway on?

[Artur Maj]

@aaron832 It says armv7l. Please, note it is not armv71 the last character is small "L" not 1 (one). This is raspberry pi 2 with ubuntu mate 15.10. I am going to edit Makefile replacing armv71 with armv7l and see what's happening. Thanks again.

Hi, i tried to make the script work but i couldnt. did anybody make it work? I used the serial gateway option, installed all the libraries.

What does it means?
Thanks

@Yveaux Keep on getting this error

@cingolanifede said:

This path doesn't exist. Create it, or change the path.
All others are warnings, due to an incompatible perl version you're using.

@Yveaux ok. Thanks. I did it. But i am having a different problem now. I have serial gateway running fine. I installed mosquitto and try to follow different steps from the forum and I dont know how to make this work.K cant make the connection beetwen openhab--mosquitto-script--serial gateway. Can you help me ? Is there any post where this is done? Thanks in advance.

[Yveaux]

@cingolanifede I don't have a step by step description for your solution. Searching (and reading) the forum sounds like a good start. If you give us a clear description of what seems to be working and what not, or where you get stuck, it's easier to help.

@Yveaux 1) The script is running. It reads from serial port, this is what I get, then it crashes, and says broken pipe.

====2)On openhab log I get this========

On openhab.cfg i put this and i have the addons installed

mqtt:mysensor.url=tcp://192.168.1.109:1883
mqtt:mysensor.clientId=mys

A simple switch setting
Switch node2_sw1 "sw1" (node2,all) {mqtt=">[mysensor:MyMQTT/30/10/V_LIGHT:command:ON:1],>[mysensor:MyMQTT/30/10/V_LIGHT:command:OFF:0]"}

I think the problem is that i am not setting mosquitto well beetwen openhab and your script. I tested an example publishing and i get the message. Do I have to change conf.d file? or setting?

Thanks.

[cingolanifede]

@Yveaux I made improvement:
I am using mosquitto_sub to read what the script posted. Thats ok.

The thing is when I start openhab this happens, it crashes and i get this error. What could it be?

[Yveaux]

The script is running for months without issues on my place; both for serial and Ethernet gateway. I am not using the script in combination with a raspberry pi. Maybe there is an issue with the version of mosquitto and/or AnyEvent::MQTT.
I remember other people having issues in combination with raspberry pi - search the forum.

[cingolanifede]

@Yveaux Thanks again. I used a phyton script. Now is working.

[robosensor]

Not sure I'm doing this right way, but changing this line:

        fh => $serialDevice->{'HANDLE'},

to this line

        fh => new_from_fd IO::Handle ($serialDevice->{FD}, "w"),

Fixed Filehandle GEN0 opened only for input bug for me on RPi 2. Fix works because of $serialDevice->{'HANDLE'} is opened as read only in SerialDevice and should not be used for write:

    # a handle object for ioctls: read-only ok
    $self->{HANDLE} = new_from_fd IO::Handle ($self->{FD}, "r");
