Arduino Uno+ESP8266-07+Soft Serial


I try to use Arduino Uno with ESP8266-07 shield with Soft Serial connection. It’s work for blynk, but I can not find example for Cayene. I choose “Arduino Uno”, “WiFi Shield”, get code but at serial monitor see only “[14] WiFi shield not present”.


Thank You


Welcome to Cayenne!

There is a post here that explains how to set it up.


Thank You for answer. So, SoftSerial for Arduino Uno+ESP8266 does not work yet?



I wanted to share that we’ve just provided support in our MQTT Arduino library for using ESP8266 as a shield :slight_smile: 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:
