Hi, I am new to Cayenne, Arduino Mega and ESP8266. I am doing an IoT based project but I can’t seem to get the ESP8266 connected. The code below was used, that was generated from the Cayenne website and the baud rate is changed to 9600. But when serial monitor is opened the ESP is not responding message is printed. However I used my mobile hotspot for the ESP8266 and I can see that the ESP is connected to the hotspot.
Hope you guys can help. I have been stuck at this for weeks.
Thanks in advanced!
