Hi,
You will find all the infos required by the MQTT module in your IBM Watson console.
Follow the tutorial here: https://cloud.ibm.com/docs/services/IoT?topic=iot-platform-getting-started#getting-started
In Step 2 Connect your device, it explains:
URL: org_id.messaging.internetofthings.ibmcloud.com
→ This is the Broker host
Port:
Device ID: d:_org_id:device_type:deviceid
→ The broker organisation
User name: use-token-auth
Password: Authentication token
Event topic format: iot-2/evt/_event_id/fmt/formatstring
→ Topic name
If you use the uncrypted port (1883) you can set the certificate options to ‘empty’.
For the timeout, set the value that suits you the best. If I’m correct, it is in seconds.
Hope it will help you!
