Hello all,
I am. Trying to store sensors data on ubidots using Esp8266 and arduino uno.
Arduino is able to send AT commands to esp8266 and esp8266 also were able to respond for this commands (I can see the response on serial monitor).
But the data I can not able to see on ubidots.
I am giving server name as industrial.ubidots.com, and port number 80.
And I have given default token number.
Please find the source code which I am using.
