Hi gadavid, The XDK uses a Paho-derived MQTT client that is able to connect to MQTT 3.x brokers. Out-of-the-Box, the XDK should be able to connect using the MQTT application username+password+clientid authentication scheme. Else, the AWS client also uses the TLS-based authentication scheme (client certificate+server validation) which you could adapt. First, see what is the authentication/login scheme needed for the IBM cloud, then you can see what parts of the code need to be configured to success connecting and sending telemetry data.
