ESP8266 Community Forum

Hi! I have the Arduino connected to the wifi ESP8266 module and when I run an empty code in the arduino it let me execute the AT commands in the serial monitor. Doing this all the AT commands are working (the module connects with the wifi modem). However, when I submit any Arduino code (other peoples code) that uses the ESP8266 to connect to the wifi modem (and thus the internet), it doesn’t work. I mean, the AT commands that the code sent are not doing anything, they are not even written in the serial monitor, neither the answers that should be received after executing them.

Any ideas?
