I was using Watson IoT platform to connect my IoT device to cloud. But now I do not know how to do it, because Watson IoT platform service was delete. So I want to know How to connect my IoT device to IBM cloud. I want to use MQTT comunication between my IoT gateway and IBM cloud service. Could you please give me some advice how to do it? I do not have any idea.
The Watson IoT platform was deprecated and withdrawn from IBM Cloud quite a while ago. There is no direct replacement so you will need to change your application depending on your use case. Check this page for more details Deprecation of IBM Watson IoT Platform on IBM Cloud
