Hi all
I want to connect my arduino mini pro to Cayenne via esp8266-01 for some IoT project
is it possible to use esp8266-01 as a WiFi shield to connect to Cayenne?
Thanks,
Lion
Hello Sir,
I am not sure if this is possible, but here is your must read post: Esp8266
Also @kreggly is the person that can answer best to your question.
Thank you.
Hi @lionlebron996 , welcome to the Cayenne Community.
You’ll be interested in this post as well, which has some example code for using the ESP8266 as a wifi shield for an Arduino.

Bumping this old thread to share that we’ve just provided support in our MQTT Arduino library for using ESP8266 as a shield We’ve done basic testing and works well. Give it a try for your project and let us know how it works out for you !
Here is the updated library on our github:
and the code can be found here:
/*
This sketch connects to the Cayenne server using an ESP8266 WiFi module as a shield connected via a hardware serial to an Arduino.
The CayenneMQTT Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager.
Steps:
1. Install the ESP8266SerialLibrary.zip library via the Arduino IDE (Sketch->Include Library->Add .ZIP Library) from the Cayenne extras/libraries
folder (e.g. My Documents\Arduino\libraries\CayenneMQTT\extras\libraries) to compile this example.
2. Connect the ESP8266 as a shield to your Arduino. This example uses the Serial1 hardware serial pins available on the Mega. You can also try
using a software serial, though it may be less stable.
3. Set the Cayenne authentication info to match the authentication info from the Dashboard.
4. Set the network name and password.
5. Compile and upload the sketch.
6. A temporary widget will be automatically generated in the Cayenne Dashboard. To make the widget permanent click the plus sign on the widget.
NOTE: This code requires ESP8266 firmware version 1.0.0 (AT v0.22) or later.
