Problem in connecting with cayenne dashboard i have check the telnet port its ok, and also by esp8266 get connected to network ssid through AT commands not by the program

On a uno right? Are you viewing the serial data via USB it looks like as I see a AT command 2nd line down? If you are, that’s one problem. On a uno you need to use a software serial and print the data to that so it doesn’t interrupt the esp rx/tx stream on serial.
