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,

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.

Thankss
