Problem in using ESP8266 with Arduino uno and Ubidots


Hello Sir
I have connected my ESP8266 board properly with the arduino but it showing GMR error and CPIN Error…
Please give me solution for this.
Waiting for reply,


Hello @nirajkapase ,

At the moment we’re working on a new library to be able to use the ESP8266 with any board using the serial ports. By now, I recommend you follow the guide to use the ESP8266 as stand alone, you can reference to this article.

Also, you can use a ESP8266 NodeMCU, you can find many examples with it on our blogs, hackster, instructables.

I hope would help you😄,
Best Regards.
