WiFi ThingSpeak Write Block Unable to Upload Data to a ThingSpeak Channel


After the code is deployed successfully on the Arduino® board, the data is not uploaded to the ThingSpeak channel. On the ThingSpeak website, the chart is not updated with the new values.


Try these options sequentially until the data is uploaded:

  1. Make sure the Arduino board is connected to Internet.

  2. Make sure the values of the Channel ID and Write API Key block parameters match the values of Channel ID and Key on the ThingSpeak website.
