After doing app start mqttPublisher and mqttSubscriber, I am not able to see the data
Jan 6 05:34:53 swi-mdm9x28-wp user.info Legato: INFO | supervisor[1101]/supervisor T=main | app.c app_Start() 3471 | Starting app ‘mqttPublisher’
I do see that the app runs successfully. Do I have to run any other commands other than specified in the legato-af/apps/sample/mqtt at 19.02-release · legatoproject/legato-af · GitHub ?

did you run the Mosquitto MQTT server on the Linux workstation
Yes, mosquitto MQTT is running on my linux system
I am able to publish messages via MQTT Explorer app and get the data using mosquitto_sub
do I have to run any other app to start seeing the data? i am not able to see LE_INFO logs as well. How can I see if the connection is established?
mosquitto_sub -t 355882100106097/messages/json

you can add some debug message in COMPONENT_INIT() function and see if you can see the message in LE_INFO().
Yes I already added that, in the publisher, but I couldnt see that logs as well.
The last line:
COMPONENT_INIT#if MQTT_SERVER_USE_SECURED_CONNECTION#else #endif
LE_INFO("Reached here, and starting");

this does not make sense.
I ran the publisher and subscriber seperately, using mkapp command, and updated the update packages, unlike given in the steps that asked me to use mksys command to run sdef file. I did not have the sdef file first and the downloaded one gave me error while running that. Do you think that it’s the issue?
And I can see INFO from hello world app.

then you can step by step port the testPublisher to the helloworld and see if the LE_INFO still works
Hi, as I was just debugging, I saw that all the other apps except mqttClient is running in the mangoh.
I can see modemService, dataHub apps running. If I need to install mqttClient app, which one I should install?
In mqttPublisher.adef
testPublisher.testPublisher.le_info -> modemService.le_info
testPublisher.testPublisher.io -> dataHub.io
testPublisher.testPublisher.query -> dataHub.query
testPublisher.testPublisher.admin -> dataHub.admin
}
