Ignore my last post. It works, I had to remove the spaces around the equals sign in the definition.

Hi,

I now get this problem;

/Users/arjo/Documents/GitHub/ncs/nrf/samples/nrf9160/arjo_mqtt/prj.conf:54: warning: attempt to assign the value " "broker.hivemq.com"" to the undefined symbol NRF_CLOUD_HOST_NAME 

Thanks,

Juan

Hi,

Add this to your asset_tracker/prj.conf file to override the hostname:

CONFIG_NRF_CLOUD_HOST_NAME="Somehost.xyz"

Please note that the nrf_cloud library is subscribing/publishing on specific topics, which is very likely not what you want in your application:

https://github.com/NordicPlayground/fw-nrfconnect-nrf/blob/master/subsys/net/lib/nrf_cloud/src/nrf_cloud_transport.c#L56

A generic mqtt publisher/subscriber example is unfortunately not available at this time.

Best regards,

Håkon
