TIDC-01002: Cannot connect my device to the cloud.

Part Number: TIDC-01002
Other Parts Discussed in Thread: SENSOR-TO-CLOUD


I'm follow the example "Sub-1 GHz Embedded Sensor to Cloud Industrial IoT Gateway Reference Design (Rev. A)" and I cannot connect my device to the cloud.

I'm not so sure if the information I provide in section step 17 are being saved properly and the same thing in section step 11. I fill up both forms and press "save changes" but in the last step I mentioned earlier, the Cloud led should turn green after saving the changes but the led never turns green, it stays red. I checked in the IBM Watson IoT Platform and the device I created stays as disconnected.

Has anyone experienced the same thing?


  • Hello Pablo,

    have you checked the output of the device on the uart terminal? 

    This will help in knowing where it can be failing.



  • Hello AB,

    Yes, I have checked the UART Terminal and this is the message that gives me after I try to enter the information in the Sensor-To-Cloud Local Dashboard.

    I did all the steps shown in the guide as slowly as possible to avoid making any mistakes.



  • I think Client ID is too long, try increasing the buffer allocated for client ID on the code or make the client ID shorter. This should fix the problem

  • Ok, I'll give it a try.

    Thank you
