Mosquitto+AirVatage+MqttClient on mangOH Green with wp7607?

gavinoimparato1 · April 12, 2021, 1:33pm

okay, I compiled and installed the file you say:

Now? On the guide i read it:

But I did not understand how to see something…

I have a problem: when I update the mqtt file I can’t find the CAN driver and when I update the generic update file I can’t see mqtt apps. So I think that it is not the correct way or not?

Now I have this problem:

error in the log:

didn’t you already make the CAN driver work before?

gavinoimparato1 · April 12, 2021, 2:05pm

yes I see them in if config (no problem ), but after these mqtt experiments, file can_iot.ko is not load…

jyijyi · April 12, 2021, 2:07pm

mqtt is just an application, no idea why it will affect the CAN driver.

how do you compile the mqtt sample?

how do you compile the mqtt sample?
using mkapp?

gavinoimparato1 · April 12, 2021, 2:11pm

I did it (mksys):

gavinoimparato1 · April 12, 2021, 2:19pm

okay I solved the problem of load module only with a powercycle

gavinoimparato1 · April 12, 2021, 3:38pm

I was able to see on two terminals that Mosquitto works: publishing on one terminal, I see the publication on the other. In your opinion, how can I do to set up a PC experiment - MangOH, or publish a message from the PC I see it then in ssh?

jyijyi · April 12, 2021, 3:50pm

no idea, I have never used Mosquitto before.

pinst · April 12, 2021, 5:11pm

I have set up a configuration with MQTT client on mangOH, mosquitto server on PC, mosquitto client on same PC. Can publish from mangOH client and receive on PC client.

It’s a Linux PC though. You have to set up the iptables on LInux to allow the mangOH to send to it. Not familiar with how you do it on Windows.

gavinoimparato1 · April 12, 2021, 5:58pm

I’m using Linux too

gavinoimparato1 · April 13, 2021, 7:04am

@pinst can you say me how you configured MQTT Client on mangOH and made Mosquitto on Ubuntu PC and mangOH in a communication pub/sub?

pinst · April 13, 2021, 6:16pm

I am not using Sierra Wireless’ MQTT Client, I am using the paho MQTT library within my application.

Here is the mosquitto server receiving a message from the paho standalone client program. Unfortunately I’m not set up to run my application on the SW at this time.

$ paho_c_pub -c localhost -t mytopic -m hello

gavinoimparato1 · April 14, 2021, 8:32am

I have errors…

gavinoimparato1 · April 14, 2021, 8:50am

@pinst Sorry for the question, but how can I do to use paho? Did you simply downloaded it? I don’t understand how to do it…for me is a good thing to have mosquitto broker and paho client

pinst · April 14, 2021, 6:22pm

Your error above is because there is already a server running. If you did an install of mosquitto the server will come up after boot. For my example I killed the existing server so I could start a new one and show the output.

The C iibrary source can be found under “MQTT Clients” on this page:
