Hello Marte

I manage to make it work, using the MQTT HELPER library, and the same prj.conf file (except I included the CONFIG_MQTT_HELPER=y).

Hi,

I cannot see anything missing or wrong in prj.conf. Can you upload the entire project so I can test it on my side?

Best regards,
Marte

Hello

Yes, I have tried to connect to test.mosquitto.org without username and password and I have the same results.

Is something wrong with my prj.conf? How can I establish MQTT connection instead of TCP?

Thank you for the support

Hi,

Based on the state in your log, you have established TCP connection, but not MQTT connection (

/** TCP Connection successfully established. */
MQTT_STATE_TCP_CONNECTED = 0x00000002

/** MQTT Connection successful. */
MQTT_STATE_CONNECTED = 0x00000004

Have you tried connecting to a public MQTT broker (e.g. test.mosquitto.org or broker.hivemq.com) without MQTT username and password?

Best regards,
Marte
