Hi, 

Assume you are using example mqtt_simple.

You shall set the server name to config variable CONFIG_MQTT_BROKER_HOSTNAME in prj.conf. And make sure CONFIG_MQTT_BROKER_HOSTNAME is not commented in this file. 

Or you can set it to MQTT_BROKER_HOSTNAME in Kconfig.

Hi,

Can you provide more information about the example?

Where is it and which one?

Are you running one example from the nRF Connect SDK?

Thanks!

Hi,

You can set m_broker_addr to your mqtt server IP address. Please note that this is an IPv6 address format.

In function app_mqtt_connect(), you can see how mqtt is setup for client.
