I’ve gone through every possible suggestion in this forum.
But i’m unable to fix the problem.
I made the connections of arduino UNO and ESP8266 as suggested in this forum.
After that as i open my serial monitor which showed me an error in opening serial port /dev/ttyACM0
I fixed this error by permitting ACM0 port by chmod command (again from the forum)
But now my serial monitor (on sending AT command) neither shows any error nor respond OK.
Please look into the issue asap as my project submission dates are nearer.
