Configuration MQTT Simple

leo_

Hello,

I'm trying to establish a connection with my own MQTT brocker on MQTT Box. I change the config on the prj.conf  and on Kconfig file, like this :

But when i rebuild the solution and run the sample, it seems like it was always the previous configuration as if the changes had not been assimilated as you can see on the picture below

    Please provide full LTE Link Monitor output to verify the connection. 

    Have you verified the MQTT connection on your computer? As there is no errors, I can't see that there is an issue. Try adding CONFIG_MQTT_LOG_LEVEL_DBG=y to our project as well. This should give more information on regarding.

    Have you verified that your setup is configured for TSL? From MQTT.org: TCP/IP port 8883 is also registered, for using MQTT over SSL. Have you tried with port 1883?

    Yes i tried the MQTT connection on my computer :

    No I didn't configure the TLS function, should we just modify the concerned line in the <prj.conf> file :

    To save the changes made in the prj.conf file, should we just rebuild and run the solution?
